Open Security Conference

Welcome to the official account of the Open Security Conference (#osco), the people-centred international gathering for everyone interested in cybersecurity.

Osco presents a different concept of security conference - literally from the community, for the community! It offers a platform to ease the learning curve in cybersecurity and provides the opportunity to learn, discuss, and teach.

#osco26 awaits! Join us November 5-8, 2026 in Rückersbach, Germany. Visit our website to learn more, and follow to stay up-to-date.
