This COcyber white paper examines how cyber incidents increasingly spill across civilian and defence domains, showing where current responses fall short while outlining practical, coordinated measures to strengthen Europe’s ability to protect and recover the critical functions that depend on interconnected digital systems.

On 12 and 13 June, COcyber held two complementary events: an in-person session in Vilnius focused on critical infrastructure protection, and an online consultation dedicated to civil-defence cooperation. The events gathered experts, partners, and stakeholders to share insights, assess solutions, and contribute to advancing cross-sector cybersecurity practices.
