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

 

Across manufacturing environments, legacy Windows systems continue to support critical operations, from machine controls and robotic systems to testing stations, packaging lines, and plant-floor automation.

 

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

 

Manufacturing organisations face a difficult balancing act between managing growing cybersecurity risks, maintaining operational continuity, supporting ageing production infrastructure, 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 production uptime and operational resilience.

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

 
47%
of manufacturing organisations experienced cybersecurity incidents involving legacy Windows systems in the past year
58%
say compatibility with legacy equipment is the biggest barrier to replacing legacy Windows systems
62%
are planning to invest in dedicated protection for legacy Windows environments

Manufacturers are balancing cybersecurity risk, operational resilience, and production continuity.
