👏 Thank you to everyone who showed up, shared, and contributed. And to @SURF for hosting us so well!

At #SecurityDays 2026, teams from NRENs across Europe and beyond took part in a Capture the Flag (CTF) competition hosted by RNP, the Brazilian NREN.

The winners? Dimitris Kolotouros and Marios Levogiannis from GRNET, who balanced quick wins with strategic problem-solving under pressure.

Beyond the rankings, the real value was in the shared experience: teams learning when to persist, when to pivot, and how to think collectively.
