Locked Shields: united in cyber resilience

Locked Shields, the world’s largest live-fire cyber defence exercise, is where nations sharpen their cyber defence strategies in real time. Hosted annually by NATO’s Cooperative Cyber Defence Centre of Excellence in Tallinn, Estonia, this high-stakes event challenges 4,000 participants from 41 countries to defend critical infrastructure against evolving cyber threats.

This keynote will take you inside the 15th edition of Locked Shields, showcasing its unique approach to cybersecurity training. From technical specialists to strategic decision-makers, participants test their resilience in complex, high-pressure scenarios designed to reflect real-world attacks.

Want to be part of the action? Whether you're a student, a government cyber operator, or a company supporting cyber initiatives, this session will show you how to get involved in future editions.

Cyber threats are evolving—so must our defences. Discover why Locked Shields is the ultimate proving ground for international cyber resilience.
