Looking Back at ONE Conference 2025

What a 2-day congress it was! The ONE Conference 2025 brought together 2.400 unique visitors from all over the world with the aim to share knowledge and make new connections within the international cybersecurity community. The conference was opened by Jan van Zanen (Mayor of the Municipality of The Hague), Dick Schoof (Dutch Prime Minister), and Matthijs van Amelsfort (Director National Cyber Security Center of The Netherlands). They emphasised the need for strategic autonomy and collaboration.
