European Open Source Security Forum

The European Open Source Security Forum brings together leaders from the open source software (OSS) community, European governments, institutions and agencies and the private sector to advance impactful security initiatives, policy efforts, and cross-collaboration.

This year’s program will feature keynotes from European policymakers, panels on regulation and emerging technologies such as open source and quantum security, targeted discussions on lessons learned from legislation like the Cyber Resilience Act (CRA), and forward-looking conversations on how to ensure open source is well-represented in future policy frameworks, along with presentations, fireside chats, and opportunities for networking.

The Open Source Security Foundation (OpenSSF), a cross-industry initiative of the Linux Foundation dedicated to sustainably securing open source software, and the Centre for European Policy Studies (CEPS), a leading think tank and forum for debate on European affairs, are co-hosting the OS Security Forum.

We invite OSS stakeholders, security experts, commercial companies and policy makers across Europe to join the journey toward a more secure future by attending the Forum on 30 October 2025 in Brussels.
