Foundation celebrates five additional members, new cyber reasoning sandbox project, and release of v1.0.0 Python Secure Coding Guide to support open source security globally
MINNEAPOLIS – OpenSSF Community Day North America – May 21, 2026 – The Open Source Security Foundation (OpenSSF), a cross-industry initiative of the Linux Foundation focused on sustainably securing open source software, today announced five new members have joined the foundation. The OpenSSF also notes additional technical resources for Python secure coding, the first cohort of OpenSSF Ambassadors, and new projects like OSS-CRS joining the foundation’s sandbox during OpenSSF Community Day North America in Minneapolis. OpenSSF’s efforts ensure that open source remains a trusted foundation for digital innovation by addressing the technical, legal, and human elements of modern cybersecurity.
These milestones address two main converging pressures in the software ecosystem: increasingly mandatory security standards and the need to unify organizations and countries behind those standards. By providing practical resources, the OpenSSF helps projects navigate complex requirements such as the CRA. The project continues to expand its global community as well, keeping all that benefit from open source software ahead of sophisticated risks and threats.
“As the threat landscape for software supply chains becomes more complex, the need for community driven security standards has never been more urgent,” said Steve Fernandez, General Manager of OpenSSF. “The growth we’re seeing in our membership and the arrival of projects like OSS-CRS show that security is an important priority for all. The OpenSSF is providing the practical tools and guidance developers need to build more resilient software.”
New OpenSSF members include ActiveState, Aikido, Minimus, and TuxCare, who join the Foundation as General Members. The FreeBSD Foundation also joins as an Associate Member. These organizations will contribute to working groups and technical initiatives to help drive the strategic direction of the OpenSSF. By collaborating within a neutral forum, these members support the long term sustainability of the open source ecosystem.
Foundation Updates and Milestones
In the second quarter of 2026, the OpenSSF achieved several milestones to secure and support more resilient software for all:

Intro Music (00:00:00)
Ejiro Oghenekome (00:01.366)
So I have embarked on a 100-day cybersecurity challenge where I post whatever I learn about cybersecurity in the open. I posted both on LinkedIn and on Twitter, currently known as X. I was told to learn publicly. It has really helped me to stay consistent and it has also helped me to stay disciplined.
Yesenia Yser (00:23.662)
Hello and welcome to What’s in the SOSS, OpenSSF’s podcast where we talk to interesting people throughout the open source ecosystem, sharing their journey, experience, and wisdom. So Yesenia, one of your hosts, and today I have the utmost pleasure of interviewing Jiro, who has been such a great part of the open source community and has done a lot for us already from part of the FAIR program.
writing a few blogs that we have seen out in the wild, and much more. don’t want to share details of the upcoming podcasts, but welcome, Ejiro. Please, you know, let’s start with you for listeners that are meeting you for the first time. Can you introduce yourself and share your journey into open source cybersecurity? Like what really pulled you into this space?
Ejiro Oghenekome (01:11.822)
Thank you very much for having me here. Hello everyone. My name is Ejiro Oghenekome. I’m a cybersecurity analyst. Currently I am contributing to the OpenSSA. So for how I got into this space and where I am at right now, I’d like to give a little backstory on myself so that I would better understand how I got to this particular phase of my career. I used to be a UI UX designer a couple of years.
But I think about 2024, I started to like not see myself doing UI UX in a long time. And as at that point, I was already interested in security. I was already curious to know how data is secured and a lot of other things about security. So I decided to dive in and take it as a career to learn about security. And the first course I took was the Google Cyber Security Certification course on
Coursera and it was a very interesting course. I took that. had other little courses that I took some on YouTube and other very, very not so prominent courses that I took that helped my career helped shape my career going forward. And something I didn’t have, I didn’t mention was the fact that I’ve always known about open source, even during my UI UX design time, but I really did not partake in open source contribution as at that point.
But I really, did not want my cybersecurity journey to be that way. So I was looking for every means to get into this space, to try to contribute to open source with my cybersecurity career. So fortunately for me during that time, I think about 2025, met a friend, told me, or I saw a post from a friend where she had an interview with someone that was talking about open source and open source security. I found that very interesting and I reached out to her.
I like to connect to the person so that they would share more light on contributing to open source, especially with my focus, which is cyber security. And she actually did that to me. She actually did that for me. And I connected with the person. The person was Sal. I a couple of meetings with Sal and she got to know where I was in my career, which led her to introduce me to the OpenSSF. And yeah, I am today trying to contribute to the OpenSSF in whichever way I can.
Yesenia Yser (03:39.854)
That’s such a great story how one friend, one webinar connected you to one individual that opened up the space of open source and it’s brought you to where you’re at today. Such a great story to hear. And one of the little birdies in the open source told me that they gave you a hundred days of cybersecurity challenge that you’ve been publicly documenting on LinkedIn. Like what inspired you to start that journey and
What do you hope would come from it?
Ejiro Oghenekome (04:10.67)
So I have embarked on a 100-day cybersecurity challenge where I post whatever I learn about cybersecurity in the open. I posted both on LinkedIn and on X. Twitter, currently known as X. So my journey can be documented. What’s made me do this was the advice I got from friends and loved ones. I was told to learn publicly. And that really has shaped me over time coming out.
because looking back, it has really helped me to stay consistent and it has also helped me to stay disciplined in terms that I feel so indebted to the cause of posting because I’ve seen a lot of people grow interest in what I have posted about my career, everything I do about cyber security. It has really been an interesting journey for me. Also, another reason why I embarked on the 100 day of cyber security challenge was because
I would say I got a rejection from an internship. I really did not get a feedback from them. So I would know, I don’t know if I should say that’s a rejection, but technically it is because I didn’t get the feedback. I really wanted to get a practical knowledge of what I was already learning. I’ve learned for a while and I wanted to get into the practical space. I wanted to get into the real world space to practice what I have been learning. Applied for the internship. Unfortunately.
I did not get it, so I had to take some step back and make a curriculum for myself where maybe I would be able to create something that feels really practical. The internship I applied for was a three-month internship, which is 90 days, if I would say technically. So I just had to do it, 90 days for an internship that I did not get. So I had to make it a 100-day for myself. Looking at all I have done, what I hope
to come out from this, which I am already saying is for people to know me for what I do. For people to know me for open source, for people to know me for open source security, for people to know me for cybersecurity, and for people to know me for preaching and being an enthusiast of open source. People should come into the open source space to contribute to open source and see the opportunity it comes with. And people to also know that
Ejiro Oghenekome (06:34.734)
I’m a cyber security analyst and I also give best practices. I also give basic knowledge of what cyber security is and all of that. Yeah, that is what I hope to get my 100 day challenge. And it has really been turning out well for me.
Yesenia Yser (06:49.836)
I love that because getting online and really just sharing what you’re learning, you know, on a cadence, whatever cadence that is for you is such an important way just for your own accountability and for others to connect to you, connect with you and learn what you’re learning, especially if you’re looking for jobs. I’m just curious right now it’s, you know, mid February. What day are you in for this challenge?
Ejiro Oghenekome (07:13.774)
Yeah, I think I’m in day 44. Nice. Yeah, day 44. It’s been a great journey. Yeah.
Yesenia Yser (07:22.574)
24 days. So when do you envision, it’s 100 days, so when do you envision this challenge ending?
Ejiro Oghenekome (07:29.39)
Let me try to do a rough calculation right now in my head. So we have a couple of these. So let’s see the beginning of around April. I’m not sure the dates for April. I’m not going to give an exact estimate, but yeah, by April I should be done with the 100 day cybersecurity challenge.
Yesenia Yser (07:50.85)
Very nice. Okay, so we’ll keep watching. you’re deep into this challenge. 44 days is a great time because that’s built in that habit to get it done and share out what you’ve learned. But I’m curious, what’s your biggest lesson that you’ve learned so far? And not just like technically, but like personally, like how have you changed how you see your learning, your discipline, or just like your community growth?
Ejiro Oghenekome (08:17.614)
Okay, that’s a very interesting question. I would really say if I’m going to put it short, I’ll say it has not been an easy journey. It’s not been easy because it’s not easy to stay consistent and trying to like, remodel my expectations of what I have to post, what I have to do. It is not easy. I’ve come to see that everything cannot go on the same pace every day.
I’ve had to stay consistent. I’ve had to understand what consistency and discipline means. I’ve come to get that. Consistency does not mean I have to be in the same place every day. I do not do the same thing every day. Some days I might not even feel motivated to want to partake in that particular challenge for that day. But have to stay disciplined. I have to stay consistent, which might make me cover less than what I covered the previous day.
Other days I might feel so motivated that I might cover more every other thing I’ve covered in the past. It just happens. One thing I’ve learned is staying consistent, what consistent really mean, being very disciplined in the space. Also it has given me a very good routine. In terms of community, I’ve come to understand that community is where I learn.
This learning can come by interacting with projects and interacting with people in the community that have more experience than I do. During my 100-day challenge, I’ve been able to have the opportunity to be part of the OpenSSF. This has gone hand in hand with the 100-day challenge that I’m doing. For the fact that I’m part of the OpenSSF and doing my 100-day challenge, I’ve seen the impact that the OpenSSF community has had on me. I’ll give a very simple example.
We had a blog post or we had a blog post that talks about a lot of things that we might go over eventually. Because of one research I did for one part of one series of the blog post, I a course on the OpenSSF and the Linux Foundation Education that I took in and I benefited from. That is the LFD121, that is developing secure software.
Ejiro Oghenekome (10:34.274)
want to understand from this journey that I’ve taken that I could learn from community, I could learn from interacting with people, want to understand what consistency and discipline mean.
Yesenia Yser (10:45.678)
That’s awesome. Yeah, I when you started being involved in the Bear Working Group, you and Saul were working on a blog series and I you just lightly mentioned it. It’s beginner to builder. What has that experience been like moving from learning to actually contributing publicly? And you know, this blog, it’s a big deal. It’s a three series blog. Like what does this authorship mean to you in the aspect of open source?
Ejiro Oghenekome (11:13.208)
Again, I would try to give an example to put what I have learned and how contributing to open source has been to me. During my design career, I’ve always known about open source, but I was not involved in open source contributions because as I did, I would say I did not know where to start. I did not know what to do. I did not know how to get into the space. I also felt most of the times that I did not know enough to be able to partake in open source contributions.
all of that and that’s feeling of mine is something I feel like a lot of other persons also do have. It was a problem for me and that problem I felt that a part of the blog post was able to solve it. One thing about me is if I experience a particular challenge or problem going forward in my career I try my best to solve it so that when people come behind me and they experience such problems they would not find it difficult to solve because they are
cases or maybe they are documentations that will help them go through this problem. That is one thing that I’ve been able to do with the blog posts and that is how, that is why the blog post publication was made public. And for me, Autorship in open source is more than just putting my name on the blog post or making contribution. It represents ownership of my learning and my voice. When I started my cyber security,
I was mostly consuming content. was reading documentations, watching tutorials and following experts. questions, I did all of that. But authorship changed the dynamics of everything for me. It shifted me from being just someone that consumed information to someone that is actively shaping the conversation, even if it was in small ways. Authorship made me feel responsible. I know that something I am going to write
is going to be published and the knowledge I share is going to be put out in the ecosystem. It would make me more focused. It would make me more thoughtful. It would make me more intentional about what I’m going to post. And this led me to call back, questions, ask people from the community to give me feedback on the blog post I wrote. I think you must have experienced that because
Ejiro Oghenekome (13:35.916)
During the first part, the second part and the third part, we were always very intentional to make sure that we got feedback from the community so that the best resources can be put out there to solve the actual problem we saw that we wanted to solve. And also, Authorship for me means visibility. As someone from Nigeria and someone who transitioned from design to cyber security, Autorship allows me to exist in a public space where people like me
are not highly represented. It shows that contributions does not have to fit a specific style or character. Also, it also makes me confident. It means that I am no longer waiting until I know everything before I can speak and before I can contribute in the open source space. Comfortable contributing while I am learning.
This is very powerful in the open source space because the open source space does not work with one person’s perfection, but it works with individuals putting together their efforts and their knowledge to try to make things work. The bear walking group and generally the OpenSSF community has really been helpful in this part. I’ve been encouraging, they’ve been friendly and they have pushed me to understand things. They have guided me each step of the way.
to understand what I am doing so that whatever resources we put out there will be the best quality for people that are going to have that.
Yesenia Yser (15:08.448)
It reminds me a lot of when I started, like just grabbing whatever kind of resources I could find and just learning. And when I realized that I was able to use my voice or my penmanship, so to speak, to share out information, I realized the power and the impact that I can have, you know, just not for my own credibility, but also you never know who’s going to read it down the line. Like I have articles that I wrote years ago or that I published that people still reference.
Nowadays that they’re like, this was an amazing article that you wrote. learned so much. So big kudos to you for that.
Ejiro Oghenekome (15:45.55)
Thank you.
Yesenia Yser (15:47.17)
Before we get into the rapid fire, I would love to know what impact you’ve seen in the community, either from your 100 day posts or your bear working group, like the work you’ve done with the blog. I know you mentioned a bit in this session, but I would love to learn, know a little bit more of looking at your journey so far. Like what impact have you seen?
Ejiro Oghenekome (16:08.634)
Genuinely speaking, I really did not think about impact when I started all of this. When I started my 100-day challenge, I was not thinking about the impact it was going to have on anyone. I just wanted to learn. When I started contributing to open source, I just wanted to learn. But over time, I started to notice little impact on people. I saw that for my 100-day challenge, people would message me saying things like, they started learning because they were following my post.
Some people asked me questions on the tools that I use and if I will be able to share resources with them. Other people said that made cyber security feel less intimidating because of course, a lot of cyber security posts we see online are from experts that would tell us in cyber security knowledge and try to express things in very technical terms for us, which could be very intimidating for beginners.
for people that are beginners that could relate to what I was saying, that could relate to very basic things in cyber security. It really felt nice. It really felt welcoming. It gave them confidence to say, okay, I could learn this. I could start somewhere. I could get some of this knowledge and get to that point of expertise where I would be able to have this opposed, intimidating knowledge also to myself. Also talking about the community.
The impact has been slightly different. I’ve been able to be part of so many decision-making. I’ve connected with experts that are very kind and friendly, and they want to see me grow. From publishing the blog series, this has made me more aware of my words, that my words could guide people that are just starting up, and this makes me feel so happy. I’m growing in the community in terms of
confidence and experience and also in transferable skills, in terms of receiving feedbacks and all of that growing. And I see that when resources are put out there, it’s really encouraging to me.
Yesenia Yser (18:22.126)
That’s awesome to hear the impacts from, I think he started maybe like a year or so ago into the organization. So it’s great to see and hear what has happened within a year.
So let’s go ahead and move on to the rapid part of the interviews. You gotta have fun with some of these parts. So I’m gonna ask you a series of this or that kind of questions or what’s your favorite X and then you just go ahead and respond. So first question, books or podcasts?
Ejiro Oghenekome (18:38.776)
FIRE!
Ejiro Oghenekome (19:02.117)
I don’t really like reading. I just have to read because I need to get those informations in my head.
Yesenia Yser (19:08.258)
Yeah, I get that. A favorite off-computer activity.
Ejiro Oghenekome (19:18.51)
enjoy cooking a lot. Yeah, enjoy cooking a lot.
Yesenia Yser (19:22.158)
What’s that one meal you cook often that you enjoy?
Ejiro Oghenekome (19:27.926)
I know if you would know, but I cook fried rice. I like seafood a lot. So I cook fried rice, prawns, salad.
That’s my favorite meal. That’s my favorite. Maybe one will see one of these days, I’ll make it and you will definitely testify to its greatness.
Yesenia Yser (19:48.086)
am ready for that. Next question. Best way to grow a project. it social media, conferences, or contributors?
Ejiro Oghenekome (19:57.44)
is social media yeah if I’m going to be very honest social media can do that
Yesenia Yser (20:03.726)
I feel like social media drives the other two. Next question, sweet or sour?
Ejiro Oghenekome (20:12.014)
No, sir, I don’t like sweets like that.
Yesenia Yser (20:16.366)
We had a quick, quick, quick change there.
Ejiro Oghenekome (20:19.575)
I just had to think about suits, so I really didn’t like suits.
Yesenia Yser (20:25.166)
I know we’re meeting early morning for you, so are you an early bird or a night owl?
Ejiro Oghenekome (20:32.386)
I I’m an early bird. I really do think I’m an early bird because I wake up very early and do things. I’m an early bird and I try to sleep very early.
Yesenia Yser (20:41.77)
I’m the opposite. just, at night I’m like a week. It’s so strange.
Ejiro Oghenekome (20:46.894)
I’m really not sleeping lot. So I just try to sleep at night. I stay awake very early in the morning. I get up very early in the morning and try to go on my day.
Yesenia Yser (20:57.464)
Yeah, I’ve adapted myself to it, but naturally I could stay up all night and sleep all day. Last question is your favorite treat or dessert?
Ejiro Oghenekome (21:10.702)
I’d say cakes.
Yesenia Yser (21:13.422)
That’s a good answer. There you had it. The rapid fire interview questions focused on food. So as we wrap things up, any advice for the next generation entering tech or security? What advice would you give them about using open source as a way to launch pad their career?
Ejiro Oghenekome (21:36.494)
Okay, well, I’ll give a disclaimer. would say I’m still part of the next generation. So whatever advice I’m going to say, I’m giving that to myself also. This is something I would have told myself earlier on in my career during design. Try to understand open source and the opportunity it provides. Also, open source is not just about coding. There are different things that someone can do in the open source space.
As a designer, could contribute to the open source space. As a writer, you could contribute to the open source space. As a community manager, you could contribute to the open source space. Obviously, very obvious ones. You could write codes. You could review codes. And you could do a whole lot of other things. Even joining calls, giving your suggestions on calls and decision making during the call is also a way to be part of the open source space.
get involved in the open source space. has a lot of opportunities for people. It’s a very welcoming space. I can testify to that from the community I am part of. It’s a very lovely community with lovely people. The OpenSSF has been a great space for me to learn and grow. And I strongly believe that this is how most, if not all of the open source communities are.
It’s a place where you can learn. It’s a place where you can build your confidence. It’s a place where you can grow. also open source is not about you being an expert. are with the knowledge you have. You could be part of an open source space. You could be part of, you could contribute into the open source. So commonly try to understand open source. is not as difficult as it might look from the outside. Trust me. in, learn.
be part of it and contribute. And I promise you it’s a very welcoming space to be part of. And talking about open source and advice I’ll give to people, have an article coming up that will be talking about contributing into the open source space generally. How to work for communities that you could contribute to, how to understand the communities, and maybe how to make it a first time contribution in a community.
Ejiro Oghenekome (23:54.668)
that you’re contributing to. This is not going to just be specifically about the open access, but open up source generally, how to be part of the space, how to try to understand the space and get into the space. Something else I would have, I would love to talk about is the opportunity for open source for us in Africa. I really don’t know that we, the idea of open source is not so widespread in Africa. That is why it has to be preached. It has to be introduced to a lot of people.
And I would love us to consider that, to try to make sure we introduce people in Africa to open source and the benefits it has on us, what it can do to us and the privileges it can give to us. Yes, that is the advice I would give to the next generation, also myself, the open source space.
Yesenia Yser (24:46.478)
Thank you so much for your time today, your impact, your contributions. I love that you have another article coming out to help those, know, explore the different open source communities and how to search. Thank you so much for everything you do within our community and all the hard work you’re putting together. I really appreciate your time and to our listeners, reach out to Jiro. She’s doing great work. Find her on LinkedIn and keep tracking on that 100 day challenge. Thank you so much everyone and we’ll catch you on the episode.
By Christopher (CRob) Robinson, OpenSSF
For the better part of two years, discussions surrounding the European Cyber Resilience Act (CRA) have been somewhat theoretical: mapping requirements, debating definitions, and analyzing how the requirements will impact our amazing ecosystem. But folks, it’s mid-2026, and the CRA is live. Theory is officially in the rearview mirror as implementation milestones roll out over the next two years.
I’ve just finished reviewing the finalized 2026 CRA Awareness and Readiness Report, a joint effort with LF Research experts, and to be blunt, the results are a sobering reality check. Despite tireless community work, the broader ecosystem is far from ready for CRA compliance.
The most disappointing finding is that awareness surrounding this regulation has decreased year-over-year. Today, 66% of respondents remain unfamiliar with the CRA, a slight increase from 62% in 2025. That means a growing portion of the software ecosystem is unaware of a regulation with global consequences and hefty fines.
The geographic disparity is even more alarming. In the United States and Canada, nearly 72% of respondents are unfamiliar with the regulation. It cannot be understated: if you are a North American company selling software products into the EU market, you are legally required to comply with the CRA. However, the majority of the neighborhood is still walking unprepared toward a September 2026 reporting deadline.
For years, organizations have treated open source like a free lunch: grabbing code and assuming the lights are being kept on by someone else. Under the CRA, that posture is no longer tenable. Manufacturers now bear the legal responsibility for the security of the components they integrate. For some (read: most) this is a stark wake up call.
Despite that, 51% of manufacturers still passively rely on upstream projects for security fixes. In the new world of the CRA, “passive” is a level 10 risk.
Many of you have tried to dodge the upstream journey by maintaining private forks, but inefficient code is still inefficient code, and now we have the bill to prove it. The report shows that maintaining private workarounds is a massive form of technical debt, costing organizations an average of $258,000 in labor every single release cycle. With some release cycles as short as a matter of hours, these costs can quickly get out of hand.
For large organizations (5,000+ employees), this burden exceeds 11,152 labor hours per cycle. Maintaining these divergent codebases is a giant bill for a strategy that actually makes supply chain transparency worse. Contributing fixes upstream isn’t just being a “good neighbor” – it’s the only financially rational path forward.
For the last several years, the OpenSSF community has observed traditional vulnerability disclosure systems buckling under the strain of volume of discoveries being reported through them. Data from the report points to a surge of 394% increase in Common Vulnerabilities and Exposures (CVEs) and an 811% spike in vulnerabilities that fall within the High+ severity categories in the first quarter of 2026. Several factors contribute to this trend:
Globally, regulations like the CRA are codifying long-standing security guidance into law. This shifts security from a “nice-to-have” recommendation to a legal requirement backed by heavy non-compliance fines.
On the bright-ish side the data reveals a clear correlation: organizational diversity is a strong predictor of a project’s security posture. When more organizations invest in a project, that project becomes more resilient, making upstream investment a direct catalyst for your own compliance posture. Organizations have an important role in their own security health through their participation in open source projects.
However, the participation of small and medium-sized enterprises (SMEs) is crucial to the entire ecosystem, they are the backbone of the industry. Currently, over half of European SMEs remain unfamiliar with the CRA, creating a significant gap in project diversity. Directed investment in SME engagement is essential to prevent compliance from becoming a structural barrier to innovation. By funding the support and tools these smaller players need to remain compliant, we ensure the entire upstream supply chain remains robust and competitive.
While we wait for the full 2026 report to drop, the tools to succeed already exist. Our previous research, Unaware and Uncertain: The Stark Realities of Cyber Resilience Act Readiness in Open Source, highlighted these same gaps a year ago. It’s time to start acting. The tools to succeed already exist and practitioners who find our resources rate them highly:
This ecosystem is rife with the talent and the collaborative instincts to meet this challenge. The December 2027 deadline is a forcing function, but it’s an opportunity to build a software supply chain that is actually secure by design.
Europe is leading the way in protecting consumers globally. Despite our geographic distance in the U.S., the oceans between us all do not provide isolation from this regulation any longer. Software and products with digital elements are built with hardware, software, and firmware created through international collaboration. That fact feeds the global economy and makes manufacturers globally responsible for CRA adherence. Events that happen “over there” DO truly affect everyone.
The results of the CRA research conducted with our peers in LF Europe is truly grave. A significant amount of work and collaboration has occurred across the ecosystem since CRA enforcement. It is shocking to look back at all this work done by both the OpenSSF and its partners and see that 39% of manufacturers, who have BILLIONS of euros at stake in potential non-compliance penalties, are still unaware and uncertain about their requirements.
The next stage in our shared journey together unfolds in September 2026 when the vulnerability reporting obligations are enforced. There is not much time to prepare. Organizations have a narrow window to audit their upstream dependencies and establish the processes needed to report and patch new vulnerabilities as they emerge. The more complex aspects of the CRA are currently a year out, coming due December 2027. Please, take action today to protect yourselves, your companies, the upstream maintainers on whom you depend, and your customers.
The OpenSSF encourages everyone that benefits from open source software to consider the beauty and complexity of the open software world. Every day in software repositories, chat channels, and mailing lists a talented cohort of developers co-engineer the tools you use and love. We ask that organizations and their leaders understand that free software is NOT free. Being a responsible consumer and participant in the ecosystem creates benefits for everyone. With CRA in our midst, there is ample opportunity to make this shared space better and more secure for everyone. My hope is that we can rise to that opportunity.

In 2023, DARPA announced a two-year long competition called the Artificial Intelligence Cyber Challenge (AIxCC) with the goal to safeguard open source software used in critical infrastructure throughout America. The intent is to hasten the development of open source AI tooling that can assist developers with finding and fixing bugs in live software with minimal cost. Open source is a drastically underfunded and underresourced form of infrastructure. It therefore presents an exciting, practical target, and opportunity for the research and development of AI in cybersecurity. Additionally, open source’s publicly observable code is ideal for competition and collaboration.
AIxCC was run in collaboration with ARPA-H and supported with contributions from Anthropic, Google, Microsoft, and OpenAI, with additional consulting around open source provided by the Linux Foundation and the Open Source Security Foundation (OpenSSF). This research was developed with funding from the Defense Advanced Research Projects Agency (DARPA). The competition consisted of two rounds, the Semifinal Competition (ASC) and the Final Competition (AFC), where cash prizes from a pot of $30,500,000 were distributed. For the ASC, 42 team submissions were accepted across two tracks; the Open Track and the Small Business Track, which required an additional technical paper submission. The top seven teams moved forward to the AFC which was set up to mimic a real world CI/CD pipeline. The scoring algorithm was also designed to highlight behaviors that would make the competing systems more useful to developers. At the conclusion of AFC, the top three teams were Team Atlanta, Trail of Bits, and Theori.
For the AIxCC competition, real open source projects were selected, and their code was forked and then modified to insert artificial bugs for the Cyber Reasoning Systems (CRS) to discover and fix. However, during the execution of the competition, the CRSs discovered several real potential bugs alongside the artificial ones. This introduced the issue of how to triage and manage resolution of fixes in the projects. OpenSSF engaged third party open source security organization Open Source Technology Improvement Fund (OSTIF) to get involved with the closing out of the bugs identified as a result of the AIxCC competition.
OSTIF selected the team at Ada Logics for their extensive experience working with open source fuzzing, bug verification, and disclosure. With a list of potential bugs identified through the course of the competition, Ada Logics was tasked with securely submitting verified issues, ensuring that anything reported to open source project maintainers was a proven bug. The Ada Logics team was able to reproduce and confirm twenty-seven issues after multiple rounds of testing and continued coordination between AIxCC competitors, collaborators, and contributors. CRS teams, including Team Atlanta, Team Buttercup, Team FuzzingBrain, Team Shellphish, Team Theori, Team 42-b3yond-6ug, and Team Lacrosse, working together with Kudu Dynamics and the OpenSSF, continued to collaborate and meet with OSTIF around the disclosures to ensure total accuracy of the reported issue’s testing and resulting decision around disclosure.
It was of utmost importance that any and all real bugs detected during the competition were verified before alerting the project maintainer to the issue. This is to differentiate how the competition reports issues to projects from the low-quality reports plaguing open source maintainers today. In several cases, CRS-generated patches were submitted alongside bugs, an offering to project maintainers looking to quickly resolve the finding. Additionally, feedback was sourced from the projects around their experience as a target in the competition as well as the disclosure procedure following.
Teams discovered twenty-seven candidate real-world issues during the competition and OSTIF engineers were ultimately able to replicate all of the draft bugs. The affected projects were cURL, shadowsocks-libev, healthcare-data-harmonization, hertzbeat, little-cms, and mongoose. Once identified, the hard work began of fixing those bugs, implementing CRS tooling to perform the second half of its double duty to find and fix security issues.
However, some of the findings did not meet a level of security concern for various reasons. Some issues were fixed by code changes in the projects during the time-period in between the competition and when engineers reproduced them. Others were outside of the threat model of the project and did not meet the criteria needed to incorporate into the project (for example, the Apache Poi project threat model states “Expect any type of Exception when processing documents,” making any exception-based findings non-issues). One issue had actually already been found by OSS-Fuzz, but the project hadn’t fixed it yet.
Ultimately, interesting findings were discovered and fixed by the Cyber Reasoning Systems in this competition, and the systems found a lot of valid issues. Further, some projects had introduced fixes before the bugs were reported. This is likely because the AIxCC teams submitted the fuzzing harnesses to the projects before triage had taken place, which re-discovered the same bugs before triage had completed. One significant lesson learned from this is that cyber reasoning systems may benefit from doing self-triage when discovering potential issues by checking against the project’s documentation and understanding the types of issues that the project accepts as security bugs that need to be addressed.
The AIxCC program was a massive undertaking by dozens of organizations, all working to contribute back to open source security in a meaningful way using novel AI tooling. The competition was mindfully designed and carried out, with attention given towards the open source projects and maintainers, the wide variety of competitors and interests, and the impact of the competition itself on the industry all the way down to the maintainers.
OpenSSF is the home for extended collaboration on these new open source tools through its newly formed Cyber Reasoning Systems Special Interest Group. OSS-CRS and FuzzingBrain, two open source projects that emerged from the competition, are now hosted at OpenSSF in the Linux Foundation. A third tool applied and was accepted to the OpenSSF, and has a few remaining steps before the official transition. The group aims to foster their development and adoption, and to establish best practices that help projects use CRSs effectively and responsibly.
This work is already producing real results. For example, FuzzingBrain has since turned its AI-assisted fuzzing system on the broader open source ecosystem, discovering sixty-two vulnerabilities across twenty-six projects, from CUPS and Apache Avro to Ghidra and OpenLDAP, with forty-three confirmed by maintainers and thirty-six already patched upstream. 42-b3yond-6ug has expanded its CRS to uncover twelve kernel-related vulnerabilities in the Linux kernel and related components, plus ten zero-day vulnerabilities in userspace projects including Eclipse Mosquitto and OpenLDAP. The team is also developing a platform to support more efficient model training and evaluation of models and agents, with a release expected soon. Using OSS-CRS, Team Atlanta discovered twenty-five vulnerabilities across sixteen projects spanning a broad range of software including PHP, U-Boot, memcached, and Apache Ignite 3. Of those, nine have been fixed and eight more have been confirmed with fixes in progress.
The future of AI assisting maintainers in finding and fixing security vulnerabilities is bright. The challenges raised by the AIxCC competition already have solutions being developed in open source, such as LLM-based tools that build threat models by looking at the data-flow of projects, and AI agents that triage findings against threat models and documentation before reporting issues. As these tools all continue to develop, they will harmonize into reliable solutions that maintainers can use to elevate their security with far less effort than today.
Our gratitude to the folks at Ada Logics for triaging the potential bugs and working hard to reproduce the issues so maintainers didn’t have to, OpenSSF for trusting us to bring together all of the stakeholders to work on the issues together, DARPA and ARPA-H for holding the AIxCC competition and sponsoring this work, the teams that built the Cyber Reasoning Systems for the competition, Kudu Dynamics for their support in confirming the findings, and all of the maintainers that worked with us to resolve the issues.
OpenSSF and OSTIF will continue to support this kind of work by serving as human connectors between CRS tools and open source communities. The goal is to help triage and validate vulnerability reports and proposed patches before they reach maintainers, ensuring findings are accurate, actionable, and respectful of maintainers’ time.
Organizing a competition of this scale on behalf of open source maintainers and its end users takes both enormous collaboration and individual effort. Understanding the communities involved, and building lightweight programs that shield maintainers from headaches while strengthening security is the best possible outcome for the ecosystem. It took everyone coming together to make this happen, and ongoing efforts will bring low-cost and low-maintenance tools to everyone that are valuable and make us all safer.
As AI moves forward at breakneck speed, innovative work like this highlights how you can move fast and build things together for a better tomorrow.

Host Sally Cooper is joined by Brandt Keller, a Staff Software Engineer at Defense Unicorns and Maintainer of the OpenSSF Sandbox Project, Zarf. Brandt discusses Zarf’s origins as a tool designed to reliably package, transfer, and deploy software components (like container images and Helm charts) specifically for critical, air-gapped environments that lack internet connectivity. The conversation explores Zarf’s evolution, highlighting its current role in introducing security gates, improving transparency, and consolidating various management and SBOM tools into a single, declarative workflow. Finally, Brandt explains how Zarf’s declarative manifest model is helping to secure open source software by reducing the cognitive burden on maintainers and giving integrators confidence in upstream artifacts.
00:01: Welcome and Introduction to Brandt Keller and Defense Unicorns
02:01: What is Zarf and its history: Solving the air-gapped use case
04:33: Zarf’s critical function today: Security, transparency, and packaging
09:18: How Zarf has evolved: From niche tool to agnostic distribution and GitOps integration
12:07: Zarf’s role in OpenSSF and securing open source software
16:05: Rapid Fire and Call to Action (Zarf.dev)
Sally Cooper (00:01.748)
Hello, hello, and welcome to What’s in the SOSS, where we talk to amazing people that make up the open source ecosystem. These are engineers, developers, maintainers, researchers, and all manner of contributors that make open source so great. I’m Sally, and today I’m really excited to be joined by Brandt Keller from Defense Unicorns. Brandt, thank you so much for being here.
And to get us started, can you tell our listeners a little bit about yourself, your role, and the kind of problems you focus on at Defense Unicorns?
Brandt Keller (00:35.742)
Absolutely. Thanks for having me. so yes, I’m Brandt Keller, primarily, a Staff Software Engineer at Defense Unicorns where I get to, know, I have the privilege of getting to focus on open source software, and maintaining that across both the open source software, projects that we have created as well as kind of the intersection of all of the things that we depend on as a company, we want to be able to be, you know,
appropriate stewards for not only consuming, but also trying to, you know, identify how we can contribute back. And so my role in particular is that of a maintainer for Zarf, which is an OpenSSF Sandbox Project. And outside of that, trying to be more of a, you know, kind of advocate in a few different spaces.
The software supply chain integrity group, working group under the OpenSSF. I try to be a contributor there, in the CNCF spaces. also contribute to, the security and compliance technical advisory group as a technical lead. And so kind of, you know, broad span, but have the definitive privilege of getting to kind of work with communities, build communities, and build technology.
Sally Cooper (02:01.972)
Oh, wow. This is so exciting to have you on the show, especially to talk about Zarf. So you mentioned Zarf. And I was just wondering if you could tell our listeners, I’m sure many of them know what Zarf is. But for those who don’t, what is Zarf and what’s its history?
Brandt Keller (02:19.02)
Yeah, for Zarf in particular, it’s, it’s evolved for sure. But I think kind of at the, at its cusp, it’s always been about trying to take this process of like, where does our software come from? and that the answer to that is varying and nuanced for everyone. but wherever it comes from, let’s try to find a way that we can package it up in a way that’s reliable and repeatable to make it secure. Ultimately, ultimately we really want to lean into that security posture.
and so what happens is software comes from many different places. people are running Kubernetes everywhere. and they have to collect all the disparate puzzle pieces in order for things to run. They have to collect their container images, their helm charts, every other file that they need to run an application. Maybe it’s their application. Maybe it’s an open source application, that their environment relies on. and we want to make that.
As easy as possible in such a way that it’s, you know, very transparent. You have everything you need. And when I say that, you know, you can maybe get to your environment and find out that you missed a piece and maybe that’s okay. But for Zarf in particular, we’ve always built for the air gapped use case, the most critical environments that don’t have connectivity back to any upstream internet connection. they have a pretty big problem here where there is no reaching back and grabbing that thing. You have to go back out and bring it back in. And that’s, been a lot of consternation for people who operate in these environments. so. Zarf really wants to make it. Let’s let’s package all that up into a single archive and make it so it’s easily transferable. It’s repeatable. So if somebody wants to take that same set of applications.
They can package it up and it’s declarative. The manifest really supports this. and in the end we have made it so that it’s, it’s a lot more repeatable to deploy to air-gapped environments where typically that has always been a lot of a juggling of many different artifacts and many different problems.
Sally Cooper (04:33.275)
Wow, yeah, that context is really helpful, especially for understanding where ZARF came from and what it was originally designed to solve. And from there, it kind of naturally leads to how ZARF is applied today. I was wondering if you could differentiate when trying to solve distinct critical environment problems.
Brandt Keller (04:53.442)
I think in the way that it’s kind of like well-postured to help people and its critical function today is to be more than its sole collection and transfer processes. We want to grab the things, we want to make sure that we have everything we need because we can’t easily reach back out. We have to go back out to the internet.
Grab more things if we don’t have them. so we want to make that process as easy to use. want to be able to kind of put those security constraints on the connected side so that we don’t bring anything that we shouldn’t bring with us to an environment that is, let’s say security critical. If you’re operating in those environments in every single piece of the, you know, software puzzle is scrutinized. we want to be very careful that nothing accidentally.
Sally Cooper (05:40.496)
Yeah.
Brandt Keller (05:51.936)
malicious or otherwise makes it into those environments. so there’s a, there’s a, you know, a wide opportunity here to introduce kind of like some security gates. how can we ensure that it’s going to be functional when it gets to the critical or secured environment? This air gapped environment in particular, is, know, first and foremost, where we, want to, you know, kind of help the community prosper. but on the outside of that is, one transparency.
If you’re pulling artifacts, where did you pull them from? What are they comprised of? And again, for those who may be operating this space, you can see, well, it’s like, well, I’m doing all those things today and that’s wonderful. but you’re probably doing them with a variety of tools. You have your, you know, container image management tool. have your Helm chart management tools. have your SBOM tooling that will then scan your.
Software artifacts. So you know what they’re comprised of know what that inventory looks like. And for Zarf, we really wanted to wrap all that up and more into a single process. You create this manifest. And after that manifest is created, you do as our package create, it’s going to grab all that stuff. We’re going to be creating SBOMS on the fly for those artifacts and putting them in the package so that again, we transfer this.
We still see things burned to CDs, as well as, that may seem. And, we want to make it so that when that artifact is in the environment, it’s very, it’s very transparent. You can look at it and be what, what am I about to install? and so there’s a, I think that’s the first layer of Zarf, which is what’s package and transfer it. there are other tools that do this and that’s wonderful. We like to kind of collaborate on solving this problem.
How do we make these artifacts more portable? but then Zarf’s kind of, you know, second, would say superpower is really to enable deployment of software. so how do you know what you deployed? Where did, where did, what are its pieces? how can you work with those pieces and kind of version control them so that the kind of parts and pieces can, you know,
be sustainable and sustainability is kind of a really big part of what we want to solve. but on the outside of that, how do we do all of that without that air gapped environment in particular, having to juggle a lot of disparate or possibly insecure infrastructure. in particular, the, problem that we most often see is that when you want to operate in an air, air gapped environment, you have to bring all this other infrastructure with you.
You have to kind of stand up a registry to pull images from and more often than not, those aren’t secured with TLS because we just want to get it up and running. We want to see that it works. and so for Zarf, we really took a step back and said, how can we bring the, everything we need for the environment to operate in such a way that we’re not going to be left with these disparate puzzle pieces of, infrastructure running that could be potentially insecure. That could be hard to maintain, hard to manage and again, leaning back into ultimately not very sustainable.
Sally Cooper (09:18.49)
One thing that stands out about Zarf is that as more teams use it in real world conditions, the project itself has continued to mature. I’m just wondering in your opinion, how has Zarf evolved?
Brandt Keller (09:34.062)
I think that it’s evolved in a variety of ways, um, kind of on the, on the cusp of in the kind of the very early days, was what’s all of a very niche use case to some. And we say that in such a way that it was like, it was very much a single, uh, Kubernetes distribution, um, air gap tool. And on its onset since then we’ve kind of seen that it really does.
prosper when we look into how can this be a, you know, a tool that is very agnostic of this underlying Kubernetes distribution model, right? Now we have cloud vendors that we want to operate with air gap in the cloud. Maybe not something people always think about, but it is very prevalent. firewalls as kind of the most basic use case of kind of isolating.
cloud infrastructure from the rest of the internet or the cloud. But then we’ve got, you know, the onset of many different new Kubernetes distributions being released, many different problems to solve where you just want to be able to transfer files and maintain, maintain state on those. And so we kind of see the evolution of, you know, taking what we’ve always wanted to solve, which is to make the transfer and deployment process easier, and then integrating the rest of the ecosystem around that.
people came to us and were requesting, you how do we integrate the GitOps ecosystem with Zarf? And how do we make it so that, you know, the mutation model, which I won’t go into unless people really want to hear about it, but how do we make it so that when some of the underlying magic is happening, that, you know, hey, that’s a really great thing, but that’s a cool pattern. Could we apply it to, let’s say, GitOps and Git?
And, you know, kind of stepping back and being like, yes, yes, we can, we can make it so that rather than it being, rather than it always being a process in the air gap where you have to transfer the artifacts and then change a bunch of references so that they point to the right place in your new environment. What’s, what’s kind of handle that for the user, let’s make it more of a, you know, nice and consolidated user experience. so it’s evolved in that way, as well as, know, kind of.
as it relates to the OpenSSF, trying to make open source software more secure.
Sally Cooper (12:21)
Love that. the mutation model, I do think we’re going to need a part two for that because now I’m super curious. But with the evolution, it’s especially interesting when you zoom out and you think about software supply chain security. You think about the broader ecosystem. Why is this a good fit for OpenSSF and how does Zarf help secure open source software?
Brandt Keller (12:30.52)
That is one of the most fun parts of my job is to really try to find new avenues, right? Zarf on again, stepping back a little bit to the early days, it’s been software integrators. They want to take software from its source. Usually these are open source projects and they want to package them up and take them to their environments.
But there’s a real like key opportunity that we’re seeing manifest here really within the last, I would say year and even last couple of months where like Zarf’s transparency models, Zarf’s packaging mechanism could be a key enabler for how software consumers look at open source projects and kind of deem, you know, how well are they doing software like supply chain security?
There’s going to be some of these like onset, I’d say issues where again, maintainers of projects, whether they’re sponsored by a company or whether they’re doing it out of their free time, because they love the technology. they only have so much time in the day. And, you know, I think supply chain security, it’s evolving quickly and it’s continuing to evolve. And most of the time that asks maintainers to do more things, right? Initially you were developing an application.
And you’re saying, Hey, it’s free for everyone to use. I’m not, I’m not asking anybody to pay me to do this. and that’s great. And then more people are like, Hey, for supply chain security, I really need to know what the SBOMs look like. Can you add SBOMs to your releases? Can you sign your releases? And you can kind of see each one of these layers is now a new cognitive burden for, maintainers to kind of normally manage, then
They have to manage the processes on top of like performing that activity. so, I kind of, see some like very distinct opportunities where. If the goal is to help secure open source software, we can really do that by using kind of like Zarf’s declarative manifest model in order for upstream projects to produce releases that consolidate all of that burden again into.
Brandt Keller (14:54.294)
A declarative manifest that they orchestrate in their pipeline, just one, one command, right? Hey, let’s do as our package create. And it’s going to create my, everything I need to run an application such as guac, for instance. we’re working with GUAC on kind of this problem statement. and it’s like, there’s some very fascinating opportunities where you’re going to have everything you need to run GUAC. You’re going to have the SBOMs for GUAC. You’re going to have.
You know, the ability to have that release artifacts signed. And so if you go back to that software integrator, they typically have wanted to deploy GUAC. would create their own Zarf package and pull all those artifacts. Well, now Zarf could just, the integrator could just do a Zarf package poll and they would have everything they would need. And they would know that it’s coming from the upstream source. They would have the confidence around it. They could check the signatures, review the SBOMs and kind of.
you know, kind of look at the posture of, Hey, everything I’ve needed now is kind of consolidated into a concise workflow.
Sally Cooper (16:05.62)
Alright, Brant, before we wrap, it’s time for Rapid, Rapid Fire. These are questions I’m going to ask you, you’re going to answer without any overthinking. No explanations, just your first instinct answers. Are you ready for Rapid, Rapid Fire?
Brandt Keller (16:32)
Let’s do it.
Sally Cooper (16:34)
Star Wars or Star Trek.
Brandt Keller (16:35)
Star Wars.
Sally Cooper (16:36)
Solid. Favorite retro video game?
Brandt Keller (16:41)
Oh, uh, Spyro.
Sally Cooper (16:46)
Ooh, nice. Marvel or DC?
Brandt Keller (16:49)
Marvel.
Sally Cooper (16:51)
Excellent. All right, and last one, favorite open source mascot?
Brandt Keller (16:56)
Oh, not counting Zarf?
Sally Cooper (16:59)
Zarf, of course, after Zarf?
Brandt Keller (17:03)
Um, probably Golang Gopher.
Sally Cooper (17:08)
Oh right, I have that one too. And Zarf is really cool. I love that. All right, perfect. No notes. As we wrap things up, what’s your call to action for our audience? If someone’s listening and wants to learn more about Zarf, try it out or to get involved, where should they start?
Brandt Keller (17:25)
They should start as a Zarf.dev, short and sweet and kind of take a look around and really what we’re trying to understand is, you know, what are the needs of users in different critical environments? I like to visit the public sector groups in a variety of different foundations to see kind of what problems they face, because most often than not, the most constrained regulatory environments are the hardest ones to solve for because they can’t rely on the internet or they have additional scrutiny and we really believe that Zarf is a a great avenue to evaluate and understand. And if it’s not, we’d love to hear from you. Like why, why not? And what are the things that we could do to improve?
Sally Cooper (18:10)
Brandt, thank you so much for joining us today and for all the work you’re doing to help secure how open source software is delivered into some of the most challenging environments. And to everyone listening, happy open sourcing and that’s a wrap.

Security teams in 2026 have no shortage of data, alerts, or findings. In 2025 alone, 48,185 Common Vulnerabilities and Exposures (CVEs) were published, a 20.6% increase over 2024’s already record-breaking total of 39,962. That works out to roughly 130 new vulnerabilities disclosed every single day, and for seven consecutive years, the annual count has hit a new record high.
The drivers are structural: the explosive growth of open source software, the complexity of transitive dependencies hidden deep in software supply chains, and an expanding CVE ecosystem that now encompasses nearly twice as many reporting organizations as it did five years ago. With 97% of commercial applications containing open source components, inherited risk has become a routine part of working with modern software.
While only 2% of all discovered vulnerabilities are ever exploited in the wild, of that small fraction, nearly 29% were exploited on or before the day their CVE was published. Attackers are selective, but once they identify a target, the window for defenders is very narrow. The window between vulnerability disclosure and confirmed exploitation is also shrinking. Whereas that timeline was over a year in 2020, it’s now shrunk to just hours.
The old model of scanning everything, triaging by Common Vulnerability Scoring System (CVSS) score, and working through a queue simply cannot keep pace with this reality. Something has to change.
The vast majority of what your vulnerability scanner finds will never actually be used against you. That means the core challenge facing security teams isn’t patching speed, but knowing where to focus. When a scanner returns thousands of findings ranked only by CVSS score, what looks like a workload problem is really a prioritization problem. Critical vulnerabilities in libraries that aren’t loaded at runtime, or in containers that haven’t run in months, crowd out the findings that genuinely matter, such as exploitable vulnerabilities in running, exposed workloads. The result is alert fatigue, missed priorities, and growing friction between security and development teams.
The OpenSSF Best Practices criteria reflect this directly. At the “Passing” level, projects must not contain unpatched vulnerabilities of medium or higher severity that have been known publicly for more than 60 days, and critical vulnerabilities should be fixed rapidly after they are reported. The emphasis here isn’t on the volume of findings processed, but on the speed and accuracy with which the most dangerous vulnerabilities are addressed, a distinction that gets lost when teams are buried in undifferentiated backlogs.
Static analysis is non-negotiable. The OpenSSF Best Practices criteria require it at the “Passing” level, and at “Silver,” projects must use tools that look for real vulnerabilities in code, not just style issues. Integrated into CI/CD pipelines, static analysis catches bugs early when they are cheapest to fix, and it remains a solid foundation of any security program. However, alone, it’s not enough.
The limitation is that static analysis sees everything, regardless of whether it matters in practice. It cannot tell you whether a vulnerable library is actually loaded in a running container, or whether that container ever receives external traffic. A CVSS 9.8 score looks identical whether the package is called thousands of times a day in a critical service or has never once been invoked in production. Runtime security fills that gap by observing what is actually executing in production. By tracking which processes are running, which packages are loaded, and which connections are being made, security teams gain much more precise intelligence about where risk actually lives.
Only 15% of critical and high-severity vulnerabilities with an available fix are in packages actually loaded at runtime. By isolating that subset, teams can reduce the scope of what needs immediate attention to a small fraction of their total backlog, in some cases by over 95%. That’s the practical difference between a list that overwhelms a development team and one they can actually act on. Static analysis provides breadth by catching everything possible during development, while runtime intelligence adds depth by showing what genuinely matters in production. Together, they give teams the context to make better decisions.
Runtime data also changes how security teams and developers talk to each other. Telling a developer “this CVE is rated 8.1” lands very differently than “this vulnerability is in a package actively loaded in your production authentication service.” The second statement connects a finding to a tangible business risk, and that context helps developers understand urgency in a way that a severity score on its own rarely does.
When security teams can bring developers a short, contextualized list of what needs attention and why, the conversation tends to shift from friction to collaboration. The OpenSSF Best Practices framework supports this kind of working relationship structurally, requiring documented vulnerability response processes, response times under 14 days, and release notes that explicitly identify runtime vulnerabilities fixed in each release. These aren’t bureaucratic requirements, but the scaffolding for the kind of consistent, trust-based communication that makes vulnerability management work in practice.
Neither team can do this work alone. Security engineers don’t always know which code paths are business-critical, and developers don’t always have visibility into what their software looks like from an attacker’s perspective. Runtime data helps bridge that gap by giving both sides a shared, evidence-based view of where the real risk lives.
Prioritization manages the vulnerability problem today, but reducing the attack surface is how you make the problem smaller tomorrow. Runtime intelligence supports two practical strategies that static scanning alone cannot.
The OpenSSF Best Practices criteria encourage minimizing the attack surface throughout, and the logic applies equally in production environments. The best vulnerability is the one that doesn’t exist because the vulnerable component was never there, and the next best outcome is knowing quickly when something unexpected is happening around the ones that remain.
The 2025 numbers make one thing very clear: the volume of vulnerabilities isn’t going down, and teams that try to treat every finding with equal urgency will continue to struggle. The more practical path is to use static analysis and runtime intelligence together, letting each do what it does best, and to use that shared context to build better working relationships between security and development teams. Finding the right vulnerabilities to fix, explaining why they matter, and making it straightforward for developers to act on them is where the real progress happens.

Over the past decade, the IT community has made significant progress in improving pre-deployment vulnerability detection. Static analysis, Software Composition Analysis (SCA), container scanning, and dependency analysis are now standard components of modern CI/CD pipelines. These tools help developers identify vulnerable libraries and insecure code before software is released.
However, security does not end at build time.
Every successful software attack ultimately exploits a vulnerability that exists in a running system. Attackers can and do target code repositories, CI pipelines, and developer environments; these supply chain attacks are serious threats. But vulnerabilities running in live production systems are among the most dangerous because, once exploited, they can directly lead to persistent backdoors, system compromise, lateral movement, and data breaches.
This reality exposes an important gap in how organizations manage vulnerabilities today. While significant attention is placed on detecting vulnerabilities before deployment, far fewer organizations have effective mechanisms for identifying newly disclosed CVEs that affect software already running in production.
Across the industry, most development teams today run some form of pre-deployment vulnerability scanning, yet relatively few maintain continuous visibility into vulnerabilities impacting deployed software after release. This imbalance creates a dangerous blind spot: the systems organizations rely on every day may become vulnerable long after the code has passed through security checks.
As the volume of vulnerability disclosures continues to increase, the industry must rethink how post-deployment vulnerabilities are detected and remediated.
Modern software systems depend heavily on open source components. A typical application may include hundreds, or even thousands, of transitive dependencies. While security scanning tools help identify vulnerabilities during development, they cannot predict vulnerabilities that have not yet been disclosed.
New CVEs are published daily across open source ecosystems. When a vulnerability is disclosed affecting a widely used package, thousands of deployed applications may suddenly become vulnerable, even if those applications passed every security check during their build process.
This creates a persistent challenge: software that was secure at release can become vulnerable later without any code changes.
In many organizations, the detection of these vulnerabilities relies on periodic rescanning of artifacts or manual monitoring of vulnerability feeds. These approaches introduce delays between vulnerability disclosure and detection, extending the window of exposure for deployed systems.
Because attackers actively monitor vulnerability disclosures and quickly develop exploits, this detection gap creates significant operational risk.
Organizations today use several methods to identify vulnerabilities affecting deployed software. While each approach has value, they are often costly and introduce operational complexity.
One common strategy involves rescanning previously built artifacts or container images stored in registries. Security teams periodically run vulnerability scanners against these artifacts to identify newly disclosed CVEs. Although this approach can detect vulnerabilities that were unknown at build time, the process cannot identify where the containers are running across system assets.
Another approach relies on host-based security agents or runtime inspection tools deployed on production infrastructure. These tools identify vulnerable libraries by inspecting installed packages or monitoring application behavior. In practice, these solutions are most commonly implemented in large enterprise environments where dedicated operations and security teams can manage the operational complexity. They often require significant infrastructure integration, deployment planning, and ongoing maintenance.
Agent-based approaches also struggle to support edge environments, embedded systems, air-gapped deployments, satellites, or high-performance computing clusters, where installing additional runtime software may not be feasible or permitted. Even in traditional cloud environments, deploying and maintaining agents across thousands of systems can be a substantial operational lift.
This complexity stands in sharp contrast to pre-deployment scanning tools, which can often be installed in CI/CD pipelines in just minutes. Integrating a software composition analysis scanner into a build pipeline typically requires only a small configuration change or plugin installation. Because these tools are easy to adopt and operate earlier in the development lifecycle, they have seen widespread adoption across organizations of all sizes.
Post-deployment solutions, by comparison, often require significantly more effort to deploy and maintain. As a result, far fewer organizations implement comprehensive post-deployment vulnerability monitoring. While most development teams today run some form of pre-deployment vulnerability scanning, relatively few maintain continuous visibility into vulnerabilities impacting software already running in production. This leaves a critical visibility gap in the environments where vulnerabilities are ultimately exploited: live operational systems.
A more efficient model for detecting post-deployment vulnerabilities already exists but is often underutilized.
Software Bill of Materials (SBOMs) provide a detailed inventory of the components included in a software release. When generated during the build process using standardized formats such as SPDX or CycloneDX, SBOMs capture critical metadata, including component names, versions, dependency relationships, and identifiers such as Package URLs.
SBOM adoption has accelerated in recent years due in part to initiatives such as Executive Order 14028 and ongoing work across the open source ecosystem. Organizations increasingly generate SBOMs as part of their software supply chain transparency efforts.
Yet in many environments, SBOMs are treated primarily as compliance documentation rather than operational security tools. Instead of being archived after release, SBOMs can serve as persistent inventories of the components running in deployed software systems.
When SBOMs are available and associated with deployed releases, detecting newly disclosed vulnerabilities becomes significantly simpler.
Vulnerability intelligence feeds, such as the OSV.dev database, the National Vulnerability Database (NVD), and other vendor advisories, identify the packages and versions affected by each CVE. By correlating this vulnerability information with stored SBOMs and release metadata, organizations can quickly determine whether a deployed asset includes an affected component.
Because the SBOM already describes the complete dependency graph, there is no need to reanalyze artifacts or rescan source code. Detection becomes a metadata correlation problem rather than a compute-intensive scanning process.
This model enables organizations to continuously monitor deployed software environments and identify newly disclosed vulnerabilities almost immediately after they are published.
To operationalize this approach at scale, organizations need systems capable of continuously tracking the relationship between software releases, deployed environments, and their associated SBOMs. One emerging concept is the creation of a software digital twin, a continuously updated model that represents the software components running across operational systems.
A digital twin maintains the relationship between deployed endpoints and the SBOMs that describe the software they run. By synchronizing these SBOM inventories with vulnerability intelligence sources such as OSV.dev or the NVD at regular intervals, organizations can automatically detect when newly disclosed CVEs impact running systems.
Rather than waiting for scheduled scans or relying on agents installed on production infrastructure, this model enables continuous vulnerability awareness through metadata synchronization.
Once an affected component is identified, remediation workflows can also be automated. Modern development platforms already rely on dependency manifests such as pom.xml, package.json, requirements.txt, or container Dockerfiles. By automatically updating these dependency files and generating pull requests with patched versions, organizations can rapidly move fixes back through their CI/CD pipelines.
This type of automation has the potential to reduce vulnerability remediation times from months to days, dramatically shrinking the window of exposure. And, it is easy to scale, giving developers more control and visibility into the production threat landscape.
Efforts across the Open Source Security Foundation (OpenSSF) ecosystem have helped establish the foundational infrastructure needed for this approach.
The OSV.dev vulnerability database provides high-quality vulnerability data tailored to open source ecosystems. Standards such as SPDX and CycloneDX enable consistent representation of SBOM data across tools and platforms. Projects like OpenVEX provide mechanisms for communicating vulnerability exploitability context, helping organizations determine which vulnerabilities require immediate attention.
Together, these initiatives create the building blocks for a more efficient and scalable vulnerability management model, one that relies on accurate software inventories and continuous vulnerability intelligence rather than repeated artifact scanning.
Pre-deployment security scanning will continue to play an important role in software development. Identifying vulnerabilities early in the development lifecycle reduces risk and improves software quality.
But the security landscape is evolving. As software ecosystems grow more complex and vulnerability disclosures increase, organizations must also strengthen their ability to detect vulnerabilities that appear after software has already been deployed.
Rethinking post-deployment vulnerability detection means shifting away from repeated artifact scanning and toward continuous monitoring of software composition.
SBOMs provide the foundation for this shift. When combined with digital twin models that track deployed software, continuous synchronization with vulnerability databases, and automated dependency remediation, organizations can dramatically improve their ability to defend operational systems.
One thing is certain: attackers ultimately focus on exploiting vulnerabilities running in live systems. Gaining clear visibility into the attack surface, understanding exactly what OSS packages are deployed, where they are running, and how quickly they can be remediated, is essential to securing live systems from cloud-native to the edge.
