The 30-day virtual Security Slam 2026 runs from October 5 to November 6, 2026 and invites any open source project to participate, offering resources, badges and awards at KubeCon NA
Engineers can adopt OpenSSF resources to meet security hygiene milestones and earn recognitions that demonstrate compliance with emerging standards such as the EU Cyber Resilience Act, while the expanded eligibility removes previous CNCF project restrictions and introduces new metrics for broader applicability

THE READ
What the cluster adds up to.
The change is the removal of the prior CNCF-only restriction, allowing every open source project to join the challenge and use the Slam Library resources to improve security posture
Adopting the resources requires time to register, follow the daily objectives and complete the prescribed security hygiene tasks, and projects must allocate maintainer attention to meet the milestones
The effort stops being optional only while the event window is open; after November 6 the structured support ends, and projects must continue their own security hygiene practices without the event-specific guidance
