When the Eindhoven University of Technology was hit by a major cyberattack, the IT team faced a critical decision: fight the intruder or shut everything down. In this episode, host Koen speaks with Joost de Jong, CISO of TU/e, about what really happened that night. Joost takes us through the process from the first alarming alert to the bold decision to take the entire university network offline. Together they unpack the chaos, communication, and tough calls that define real-world crisis management in cybersecurity. Discover how trust, preparation, and clear priorities can make all the difference when every second counts.
