OT Vulnerability Management for Industrial Equipment Makers
Your customers schedule downtime months in advance, and an unplanned outage costs more than the vulnerability. Finite State helps you tell them precisely which builds are affected, which exposure is reachable, and what to do about it.
The Challenge
Industrial Products Outlive the Tooling Built for Them
A controller designed today may still be running in a substation twenty years from now, in a configuration nobody remembers choosing. Vulnerability management built for software releases assumes none of that.
Variant sprawl
One product ships in dozens of configurations, each with a different component set.
Decade-long support
Firmware in the field needs answers long after the engineering team moved on.
Patch windows are rare
Asset owners schedule downtime months out, so precision matters more than volume.
Evidence expected
IEC 62443 and customer contracts both ask how you handle vulnerabilities, in writing.
Our Approach
Track Exposure Per Build, Not Per Product
The Product Security OS analyzes each firmware build you ship and maintains a component inventory for every one. Vulnerability status is tracked against those builds, so an answer about a specific configuration in a specific plant is already there when someone asks.
Variants and Lifecycles
Every Configuration Answered Separately
Different builds of the same controller can carry different libraries, different kernels, and different exposure. Finite State keeps a ground truth software inventory for each one and holds it across the product's life in the field.
One Record for Every Configuration Shipped
Per build
Maintain a component inventory per build, not per product line
Compare builds to see what changed between firmware releases
Flag components reaching end of life or losing upstream support
Keep records intact for products still deployed years after release
Prioritization
Precision Is Worth More Than Coverage Here
When a fix requires scheduled downtime, telling a customer to patch something unreachable costs real money. Reachability-driven prioritization determines whether a vulnerable function can actually be reached in the shipped build before anything gets escalated.
Reachable in This Build, or Not
Before escalation
of detected CVEs analyzed for reachability
Reachability results returned in under an hour
- Prioritize by reachability, exploit availability, and exposure in the specific build
- Weigh CISA KEV listings and exploit prediction alongside severity
- Re-evaluate automatically as new disclosures land against components already shipped
- Record every not-affected determination as a VEX decision with its analysis
Response Options
Not Every Finding Ends in a Patch
OT teams often can't update immediately, so a defensible program has to support several response paths and keep the reasoning behind each one.
Patch
Update or replace the affected component when a validated fix is available.
Mitigate
Reduce exposure through configuration, architecture, or access restriction.
Monitor
Track exploitation and change conditions against documented review criteria.
Accept
Record a time-bound risk decision with ownership and rationale.
Investigate
Hold the finding under review while presence, reachability, or impact stays uncertain.
Whichever path you take
- Generate VEX decisions covering affected and not-affected builds
- Export component and vulnerability detail for customer security questionnaires
- Keep the determination attached to the build, the owner, and the evidence
- Re-open the decision automatically when the software or the threat picture changes
Operational Impact
Finite State Removes What Was Never Exploitable
Most of what a scanner reports was never reachable in the build that shipped. Finite State proves which findings those are, so your engineers work a list that reflects real exposure.
Scale and Precision
Unreachable findings removed in two years
Reduction in vulnerability noise
Vulnerability triage cycle
Scans automated every month
What Changes for Your Team
One answer per build. Configuration-specific exposure instead of a product-level guess.
Records that survive turnover. Determinations stay attached to the build that shipped.
Evidence for IEC 62443. Vulnerability handling gets documented as it happens.
