Description

Preparing for the Next Cyber Crisis: Insights from Exercises Across Europe

This session explores how cyber crisis exercises can strengthen real‑world readiness across organisations and communities. You will hear practical insights from recent large‑scale exercises such as Cyberfortress and TALON, including lessons learned.

We also take a closer look at the structure and key quick wins from the TALON exercise, followed by a discussion on how these types of exercises can continue evolving within our community.
