Europe’s critical infrastructure — spanning energy, transport, digital networks, and undersea cables — forms the backbone of its economy and security. Yet these systems are increasingly vulnerable to hybrid threats, ranging from cyberattacks and sabotage to the weaponisation of strategic dependencies. Recent incidents have shown that disruptions to energy flows or data connectivity can quickly escalate into broader economic and political crises, highlighting how infrastructure security is inseparable from Europe’s strategic autonomy.
Addressing these risks raises urgent questions of preparedness and resilience. The EU must combine infrastructure protection with a stronger capacity for coordination. This means improving collective threat detection and response capacities, tightening security standards across sectors, and fostering public–private cooperation to anticipate vulnerabilities.
Fundamentally, it is also about wider trust and reliance. The EU must urgently clarify which third-country software, equipment, or service providers can be safely integrated into its critical systems. Determining these boundaries is essential to mitigate vulnerabilities without unnecessarily fragmenting global cooperation and supply chains.
