Problem
Legacy Control Systems
Industrial sites often rely on older PLCs, SCADA platforms, unmanaged switches, unsupported operating systems, and vendor-specific communications.
Typical impact
What this can affect
- unsupported software exposure
- insecure remote access
- limited patching options
- poor documentation
- operational dependency on ageing assets
Engineering response
Identify the dependencies and failure consequences around each legacy asset, then select compensating controls, recovery measures or a managed replacement path.
