seL4 News

The seL4 Foundation thanks Collins Aerospace for becoming a sponsor of the seL4 Summit 2025. Collins Aerospace has generously sponsored the seL4 summit every year since 2023.

Collins Aerospace, part of seL4 Foundation member RTX, has been a long-time core participant in the seL4 ecosystem. Collins was a prime contractor in the DARPA HACMS program which demonstrated the seL4-based incremental cyber retrofit of autonomous military vehicles. This was a major milestone in the growth of seL4, demonstrating that it protects against cyber attacks on real systems in operation. The same team also led the follow-on DARPA CASE program, aiming at designed-in cyber-resiliency, including the seL4-based framework for verified initialisation and configuration of systems architectures.

Collins Aerospace is now leading a team on the DARPA PROVERS program which has a goal of enhancing the security of defense and aerospace systems by dramatically improving the usability, flexibility, and accessibility of formal methods-based development and verification tools, and targeting seL4 as an implementation platform.

The seL4 Foundation is pleased to welcome Germany's Cyberagentur as Associate Member, coinciding with the launch of five projects in its research program on an “Ecosystem of formally verified IT — provable cybersecurity (EvIT)”.

Two of the projects include work enhancing seL4. The Cyberagentur is joining the seL4 Foundation to underline the importance of this approach for making both highly complex IT systems and critical infrastructures more secure and to attract further supporters. The Cyberagentur funds cybersecurity research projects with a high risk and a very high potential of disruption.
