The Dutch Ministry of Justice and Security, together with the National Coordinator for Security and Counterterrorism (NCTV), faced the urgent challenge of strengthening national cybersecurity resilience. Cyber threats are cross-sectoral, fast-moving, and geopolitical by nature. Public and private organizations often struggled to share intelligence and coordinate effectively. The ambition of the Cyclotron Program is to create a structural information-sharing ecosystem between ministries, national security bodies and private cybersecurity actors.

Fronteer acted as strategic coalition-builder, co-designing the ecosystem architecture and governance for Cyclotron. We facilitated co-creation sessions with over 40 organizations, mapping interests, barriers, and shared goals. Together, we developed a blueprint and launched three operational collaboration centers. We also created a tailored co-creation toolkit, roadmaps for resilience products, participation criteria, and a joint code of conduct. Alongside this, we established use cases and testbeds for learning, experimenting, and scaling.

Cyclotron is a robust, trusted ecosystem that enables public and private actors to collaborate on cybersecurity challenges. The program now supports structural intelligence-sharing, joint product development, and aligned strategic priorities with Dutch and European cybersecurity agendas. Beyond infrastructure, Cyclotron has built long-term trust and ownership across stakeholders, providing the Netherlands with a future-proof model for public-private cyber resilience. It stands as a benchmark program, showing how coalition-building and co-creation can unlock national security innovation in a geopolitical context.

October 2025 marked a true milestone: the coalition ‘convenant’ was signed by 28 founding members.
