EU auditors say weak incident data sharing is undermining European cyber defenses
The report argues that the problem is not only defensive technology but whether governments actually share useful incident information fast enough.
The European Court of Auditors said poor information sharing among member states is weakening the EU's collective cybersecurity defenses.
The auditors pointed to incidents where significant disruptions occurred without timely reporting to EU cybersecurity bodies and said national rules can hinder cross-border sharing.
Why it matters
Large cyber incidents routinely cross company and national boundaries. Defensive capability depends on rapid, actionable intelligence, not merely spending on tools. Fragmented reporting can prevent other organizations from recognizing an attack pattern while it is still spreading.
