Technical Resilience Day
On Tuesday, 4 November 2025, SURF is organizing a themed event on Technical Resilience in education and research. This event is intended for both CISOs and operational security professionals, and is entirely focused on strengthening digital security, from testing approaches to red teaming, and from DNS security to joint future explorations.

- Congress building De Vereeniging, Mariaplaats 14, Utrecht.
During the programme:
- We’ll share insights on the approach “from Check to Hack”
- Introduce the ART-SURF red teaming framework
- Explore real-world examples from institutions
- Delve into topics such as DNSSEC and DNS firewalls
- Gather your input, ideas, and inspiration
And of course, we’ll round off with networking drinks.

This meeting is intended for both CISOs and operational security professionals. The sessions are in Dutch.
