Summary

• Cyber Europe 2026 simulated attacks on rail and maritime networks across Europe.
• The exercise tested the EU Cyber Blueprint and Cybersecurity Reserve, with the UK, Norway, Switzerland, and Ukraine also involved.
• Transport cyber resilience now sits directly inside trade, logistics, military mobility, and emergency response.

The European Commission has used a large-scale cyber exercise to test how Europe would respond to attacks on rail and maritime networks, bringing together around 5,000 experts from public authorities, private operators, EU institutions, and partner countries.

Cyber Europe 2026, organised by the European Union Agency for Cybersecurity, ran on 10 and 11 June and simulated a serious attack on critical transport infrastructure. The scenario covered disruption across rail and maritime networks before escalating into a wider cybersecurity crisis.

The United Kingdom, Norway, Switzerland, and Ukraine also took part, widening the exercise beyond the EU’s internal machinery. That cross-border design reflects the way transport systems work in practice, with ports, rail freight, passenger services, logistics platforms, shipping data, and public authorities all dependent on systems that do not stop neatly at national borders.

The Commission said the exercise was the first EU-wide test of the 2025 EU Cyber Blueprint, which sets out roles and responsibilities during a cyber crisis. It also tested the Cybersecurity Reserve created under the Cyber Solidarity Act, a mechanism designed to support responses to serious incidents.

Transport is a demanding test case for cyber planning because disruption moves quickly from systems to services. A compromised port system can slow trade, delay industrial inputs, and create problems for customs, insurers, hauliers, and shippers. A rail incident can affect passengers, freight, emergency planning, and public confidence, while also raising questions about how quickly operators can work manually if digital systems fail.

Cyber exercises are often described as technical rehearsals, although their value is usually organisational. A serious incident forces decisions about operational continuity, communications, law enforcement, insurance, public warnings, contractual liability, and escalation between national and European bodies. The weakness exposed in a drill may be a missing process, a slow reporting route, or an unclear decision owner rather than a firewall rule.

Including policymakers and industry alongside security specialists gives the exercise more practical weight. Critical infrastructure operators need to know who decides when a simulated disruption becomes a live crisis. Regulators need to understand whether reporting routes are workable under pressure. Governments need to test whether national procedures can mesh with EU-level structures quickly enough to be useful.

The exercise also lands as Europe tightens its cyber regime through NIS2, the Cyber Resilience Act, and other resilience measures. Transport operators and suppliers are being pulled into a more formal environment where cyber preparedness is connected to compliance, procurement, and operational licensing.

The next useful marker will be what changes after the exercise. Clearer escalation paths, better information-sharing, and more realistic assumptions about manual fallback would all make Europe’s transport systems less brittle. Rail and maritime infrastructure are not sectors sitting beside the digital economy; they are the physical routes through which the economy keeps moving.
