OT Vulnerability Management Program Development

A patch-and-vuln program the plant can actually live with — prioritized by production impact and compensating controls, not a thousand-line CVSS spreadsheet nobody actions.

Most OT vulnerability programs got copied from IT and bolted on. The scanner runs across the IDMZ once a quarter and produces a thousand-line spreadsheet. Plants ignore it because patching a PLC at 0200 is not a thing, and the CVSS-9 list sits on the CISO’s desk while the real exposure goes untouched.

This service builds a program the plant can live with. We prioritize by production impact and exploitability in context, define compensating controls where patching is not an option, and set a remediation cadence operations will actually run.

You get vulnerability management that reduces risk instead of generating reports, with every item tracked to closure in Resilion.

Frequently asked questions

How does OT vulnerability management differ from IT?
You often cannot patch a PLC at 0200, so a CVSS-ranked spreadsheet is useless. An OT program prioritizes by production impact and exploitability in context, leans on compensating controls when patching is not feasible, and runs on a cadence operations can actually sustain.
What do you build?
The full program: asset and vulnerability sources, a prioritization model tied to plant impact, compensating-control playbooks, and a closure cadence — wired into Resilion so remediation is tracked, not lost in a spreadsheet.
