Cybersecurity matters more than ever. The ONE Conference inspires cross-border cooperation between cybersecurity professionals from business, science as well as government organisations. An exclusive yearly event, the ONE Conference is all about connection.

ONE Conference

The ONE Conference is Europe’s prime cybersecurity event. A leading platform for sharing knowledge, best practices and research results. This year’s edition will take place on 30 September & 1 October 2025. Both days will offer a plenary programme as well as optional breakout sessions in smaller groups.

A wide variety of topics will be addressed: from highly technical subjects such as malware detection, incident response, and law enforcement cases to less technical subjects, such as partnerships between the public and the private domain, governance and recent cybersecurity research.
