    From Chaos to Resilience: Key Takeaways from the CLAW 2024 Crisis Exercise

    In the first week of December 2024, we participated in CLAW, GÉANT’s annual crisis exercise.

While our work in security product management and awareness rarely places us in the middle of a crisis, we were eager to gain a first-hand understanding of crisis handling and its broader implications for building organisational resilience.
