Europe has invested heavily in cybersecurity, but a new report from the European Court of Auditors highlights a persistent weakness: information about cyber incidents is not always shared quickly enough across member states.

The auditors found that inadequate information sharing is undermining the effectiveness of EU cybersecurity cooperation.

What is the problem?

Cyberattacks rarely respect national borders.

An attack on one organization can affect suppliers, customers and infrastructure in several countries.

Yet national security rules and different reporting practices can make cross-border information sharing difficult.

The European Court of Auditors noted that even serious incidents have not always been reported to EU cybersecurity authorities in a timely and actionable way.

Why does this matter for AI?

AI is making cybersecurity more automated.

AI agents can discover vulnerabilities, execute actions and interact with multiple systems at high speed.

That means incident response also needs to become faster.

If one organization identifies a new AI-enabled attack pattern, sharing that information could help other organizations defend themselves.

What businesses can learn

Enterprises should treat cybersecurity information as an operational asset.

Incident response plans should define:

What qualifies as a reportable incident

Who receives the alert

What technical information is captured

How quickly information is shared

Which external authorities must be notified

This becomes even more important for organizations operating across multiple European countries.

The bigger picture

Cybersecurity is increasingly a collective problem.

No organization sees every threat.

No government sees every attack.

And AI-enabled threats can evolve faster than traditional reporting processes.

The European Court of Auditors' findings therefore reinforce a simple principle: strong cybersecurity requires not just better defenses, but better information flow between the organizations responsible for those defenses.
