Looking Back: Highlights from Last Year
At SOSS Community Day EU 2024, held on 19 September in Vienna, the OpenSSF community came together for a powerful day of discussion, collaboration, and learning. We saw inspiring keynotes from leaders at Intel, GitLab, CISA, Cisco, and more, covering topics from vulnerability disclosure to the future of secure AI. Tracks explored everything from software supply chain resilience and cryptographic model signing to gamified security training and national policy engagement.
Recordings are available — and we’d love for you to be part of the story this year.
