2026 ANNUAL RESEARCH REPORT

TRANSPORT EDITION

 

More than half of Europe’s transport organisations have already experienced cyber incidents linked to legacy systems

 

New 2026 research reveals why legacy OT remains a growing cybersecurity challenge across transport environments and how organisations are responding.

Legacy Windows systems are becoming a growing operational and cybersecurity challenge for transport organisations

 

Across transport environments, legacy Windows systems continue to support critical operations, from signalling controllers and depot management systems to passenger information platforms and operational infrastructure.

 

But while these systems remain essential, they are also becoming increasingly difficult to secure.

 

For many organisations, replacing legacy systems is not a realistic short-term option. The challenge is finding practical ways to reduce risk while keeping operations running.

Transport organisations face a difficult balancing act:

Managing growing cybersecurity risks

Maintaining operational continuity

Supporting ageing infrastructure

Modernising without disrupting critical services

Legacy systems aren’t going away. But the risks are increasing.

 
56%
of transport organisations experienced cybersecurity incidents involving legacy Windows systems in the past year
53%
say compatibility with legacy equipment is the biggest barrier to replacing legacy Windows systems
64%
are planning to invest in dedicated protection for legacy Windows environments

Transport organisations are caught between cybersecurity risk and operational reality.
