European Court of Auditors warns poor data sharing undermines EU cyber defences
Summary
On September 21, the European Court of Auditors reported that poor data sharing among EU member states is significantly hindering the bloc's ability to combat cyberattacks. Despite the EU's increasing investment in cybersecurity, with €1.4 billion allocated in its current budget, the court emphasized that this lack of cooperation is the "Achilles heel of the entire system." The report highlighted a ransomware attack in September 2025 that disrupted major airports across several countries, pointing out that none of the affected nations notified the EU cybersecurity agency or their fellow members. This issue is compounded by national security legislation in individual EU countries, which obstructs timely information sharing during cross-border incidents. In response, the European Commission has launched legal proceedings against France, Ireland, the Netherlands, and Spain for their failure to align national laws with EU requirements concerning cybersecurity information sharing.
