Open Source SecurityCon (evolved from Cloud Native SecurityCon) returns for its second event, co-located with KubeCon + CloudNativeCon Europe 2026. The conference is dedicated to advancing innovation and collaboration across open source software security and cloud native security, bringing together creators, maintainers, operators, and consumers who are actively involved in securing the software ecosystem.
As open source continues to power modern infrastructure, the need to strengthen security practices across projects and production environments has never been more important. Open Source SecurityCon provides a focused space for the community to share insights, examine emerging challenges, and collectively improve the security posture of the cloud native ecosystem.
Who will get the most out of attending this event?
Open Source SecurityCon offers valuable insights for anyone, including those outside of a security practitioner role, who are involved in building, maintaining, or securing projects, platforms, or services. This includes open source maintainers, platform engineers, security practitioners, and operators running workloads in production.
Security is a shared responsibility across the entire software lifecycle—from development outputs to production deployments. Attendees will benefit from exploring ecosystem-wide challenges, identifying areas of weakness that may affect their own environments, and learning practical strategies to address them.
What is new and different this year?
This year’s program focuses on the latest advancements in security across policy, processes, and technology. The agenda spans topics from the implications of AI to foundational improvements in software supply chain security.
Attendees will gain insight into securing development outputs, strengthening existing systems, and addressing more complex, community-supported security challenges. The program reflects the evolving landscape of cloud native security and the growing importance of implementing secure practices at scale.
What will the day look like?
Open Source SecurityCon is designed as a single-stage event to encourage shared learning and broad participation. The day will feature a diverse lineup of deeply technical talks spanning topics from regulatory compliance to quantum cryptography, along with a high-profile panel and a series of lightning talks.
Sessions will explore advancements across security domains, offering perspectives that connect policy, engineering practices, and emerging technologies.
Should I do any homework first?
No specific prerequisites are required, but attendees are encouraged to approach security from a variety of perspectives, fueled by curiosity. Reviewing the schedule ahead of time can help you identify topics that genuinely interest you and see how they connect across different areas.
Security is often just one dimension of a broader technical focus. Thinking about how it intersects with your areas of interest will help you get the most out of the day.
Find your community!
Developing secure software in the open source domain at scale presents ongoing challenges, especially when feature development can move faster than security prioritization. Open Source SecurityCon brings the community together to highlight essential issues, share lessons learned, and foster collaboration across projects and organizations.
By creating space for open discussion and collective problem solving, the event helps strengthen the cloud native community and support the next wave of security leaders.
