Cyber Europe 2026 tests EU response to large-scale cyber crises

More than 5,000 participants took part, with the EU Cybersecurity Reserve and updated crisis response Blueprint tested for the first time.

Cyber Europe 2026 tested the EU’s ability to respond to large-scale cyberattacks

The EU Agency for Cybersecurity has led Cyber Europe 2026, a two-day exercise testing Europe’s response to large-scale cyberattacks on rail and maritime transport networks.

The exercise, held on 10 and 11 June, brought together more than 5,000 participants from national cybersecurity agencies, EU and EFTA public and private sector organisations, the EU entities and industry. It was designed to strengthen cyber preparedness and test the continuity of essential services during a major crisis affecting interconnected transport systems.

The scenario simulated coordinated attacks on critical maritime and railway infrastructure across Europe. Port logistics and navigation systems were compromised, cargo movements were halted, and safety risks emerged. Railway networks were also disrupted, with cross-border trains frozen and passengers and supplies delayed.

Participants also had to respond to ransomware attacks affecting transport authorities and ticketing services, as well as exposure of sensitive passenger and emergency information. ENISA said the scenario required information-sharing and coordination at technical, operational and political levels.

Cyber Europe 2026 also tested the EU Cybersecurity Blueprint, revised in 2025 to strengthen crisis management for large-scale incidents. For the first time, the EU Cybersecurity Reserve was tested under Cyber Europe, using a scenario that required participants to follow ENISA procedures for activating incident response support under the mechanism.

ENISA said findings from the exercise will be analysed in after-action reports to identify weaknesses and improve Europe’s preparedness and response processes.

Why does it matter?

The exercise shows how cyber incidents affecting transport infrastructure can quickly move beyond technical disruption into broader economic, safety and crisis-management risks. Ports, railways, logistics systems, ticketing platforms and navigation tools are increasingly interconnected, often combining legacy operational technology with modern digital systems. Testing EU-level coordination matters because attacks on transport networks can affect trade, military mobility, emergency response and public trust across borders.
