Brief Overview
- Efforts for cyber defence in the European Union are hindered by insufficient data exchange among member nations.
- The EU has allocated €1.4 billion ($2.25 billion) towards enhancing cybersecurity.
- The deficit in information exchange is referred to as the “Achilles heel” of EU cybersecurity.
- A major ransomware incident in 2025 went unreported by the impacted countries.
- National security regulations are obstructing cross-border information exchange.
- No significant cybersecurity event has been documented since 2016.
- France, Ireland, the Netherlands, and Spain are facing legal measures due to non-adherence to EU information-sharing regulations.
EU’s Cybersecurity Funding and Obstacles
The European Union is making substantial investments in its cybersecurity framework, with a current budget of €1.4 billion aimed at bolstering its cyber defences. Nevertheless, a report from the European Court of Auditors indicates that these initiatives are being weakened by a pronounced lack of information sharing among the member states.
The Critical Weakness: Insufficient Information Exchange
The report points out that poor data sharing is the “Achilles heel” of the EU’s cybersecurity framework. A prompt and actionable flow of information is essential for an effective response to cyber threats, which is currently lacking. This shortcoming diminishes the overall effectiveness of the EU’s cybersecurity systems and protocols.
Unreported Cyber Events
In September 2025, a ransomware attack struck a technology provider servicing the aviation sector, disrupting major airports throughout Europe, such as those in London, Brussels, Berlin, and Dublin. Alarmingly, none of the impacted nations informed the EU cybersecurity agency or other member states, showcasing the gaping hole in information exchange.
Obstacles to Information Exchange
Legislation pertaining to national security in individual nations is identified as a major hindrance to effective cross-border information sharing. This legal backdrop frequently obstructs the necessary communication between countries when incidents arise.
Legal Proceedings and Non-compliance
In spite of EU regulations demanding information sharing, no EU country has reported a “large-scale” cybersecurity event since 2016. The European Commission has recently referred France, Ireland, the Netherlands, and Spain to the EU Court of Justice for not aligning their national legislation with EU directives regarding cybersecurity information sharing.
Conclusion
The European Union’s commitment to cybersecurity is laudable, yet ineffective information exchange among member states undermines its cyber defences. The absence of timely and actionable information jeopardizes the EU’s capacity to address cyber threats, presenting a significant danger to its collective security.
Reader questions
Frequently asked questions

Why is exchanging information essential for EU cybersecurity?
Information exchange is crucial as it enables timely reactions to cyber challenges, thereby improving the overall efficiency of cybersecurity strategies.
What are the repercussions of failing to share information about cyber events?
The lack of information sharing can result in disjointed responses, heightened vulnerability, and extended recovery from cyber issues.
In what way are national security laws impacting information sharing?
National security laws frequently limit the flow of information across borders, obstructing collaborative efforts to counter cyber threats.
What measures is the EU implementing against non-compliant member nations?
The EU has initiated legal actions against states that have not modified their legislation to align with EU directives on cybersecurity information sharing.
Have there been any enhancements in EU cybersecurity measures?
Although significant investments and some improvement in cooperation have been made, the lack of information sharing continues to be a pressing concern.
What was the consequence of the ransomware incident in 2025?
The incident caused disruptions at major European airports, underlining the repercussions of insufficient information sharing.
