PHARMA EDITION
More than half of Europe’s pharmaceuticals organisations have already experienced cyber incidents involving legacy systems
New 2026 research reveals why legacy OT remains a growing cybersecurity challenge across pharmaceutical manufacturing environments and how organisations are responding.


Legacy Windows systems are becoming a growing operational, cybersecurity, and compliance challenge for pharmaceutical organisations
Across pharmaceutical production environments, legacy Windows systems continue to support critical operations, from batch controllers and cleanroom monitoring systems to serialisation stations and manufacturing execution systems.
But while these systems remain essential, they are also becoming increasingly difficult to secure.
Pharmaceutical organisations face a difficult balancing act between managing growing cybersecurity risks, maintaining GMP-compliant operations, supporting validated production systems, and modernising without disrupting manufacturing processes.
For many organisations, replacing legacy systems is not a realistic short-term option. The challenge is finding practical ways to reduce risk while maintaining operational continuity and regulatory compliance.
Legacy systems aren’t going away. But the risks are increasing.
Pharmaceutical manufacturers are balancing cybersecurity risk, operational continuity, and regulatory requirements.
