Regulations
Business Context
Many industrial facilities continue operating legacy controllers and
operating systems because they remain reliable and support critical
production processes.
The Contradiction
Long equipment life maximizes operational value.
Modern cybersecurity requires supported and secure platforms.
Why It Exists
Legacy systems often cannot support current security updates or
authentication mechanisms while remaining essential for production.
Direction
Protect legacy assets through network isolation, application
whitelisting, virtual patching, and phased modernization programs.
