KubeCon + CloudNativeCon Europe 2026 Co-located Event Deep Dive: Open Source SecurityCon

Who will get the most out of attending this event? What is new and different this year? What will the day look like? Should I do any homework first? Find your community! Posted on February 23, 2026 by Co-chairs Brandt Keller & Constanze Roedig 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. 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. 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.
