OT Vulnerability Management
Evaluate vulnerability exposure with operational context
In OT, the question is rarely just whether a vulnerability exists. It is whether it applies, whether it is reachable, what happens if it is exploited and what can realistically be done before the next maintenance window.

In short
OT vulnerability management is the process of identifying which published vulnerabilities affect your industrial assets, assessing their real exposure and operational impact, and deciding whether to patch, mitigate or accept them — with the decision documented.
The challenge
Vendor advisories and vulnerability databases publish a steady stream of issues affecting industrial products. Many are not applicable to a given installation; others are applicable but cannot be patched until a planned outage or vendor qualification.
Without a structured process, teams either ignore advisories or chase every one equally.
Scope and activities
The service reviews your process and current exposure:
Asset and software version information
Whether versions are known well enough to match advisories.
Vendor advisories and vulnerability records
Sources monitored, such as vendor PSIRTs and national CERT advisories.
Applicability verification
Confirming whether affected products, versions and features are present.
Operational impact
What exploitation could mean for the process and safety.
Patch feasibility and maintenance constraints
Vendor approval, testing, outage windows and dependencies.
Compensating controls
Segmentation, access restriction, disabling features or monitoring as interim measures.
Tracking and reporting
How decisions, deadlines and residual exposure are recorded.
Potential deliverables
Final deliverables depend on the agreed engagement.
- Process reviewStrengths and gaps in your current vulnerability handling.
- Applicability and exposure reviewAssessment of a defined set of advisories against your assets.
- Prioritized mitigation planPatch, mitigate or accept decisions with rationale.
- Procedure recommendationsImprovements to keep the process running.
Engagement approach
Baseline
Review asset version data and the current advisory process.
Match
Compare an agreed set of advisories against your asset information.
Assess
Verify applicability and evaluate exposure and impact.
Decide
Recommend patching, compensating controls or documented acceptance.
Embed
Improve the procedure and tracking so the work continues.
Assumptions and limitations
- This is an advisory service based on available asset and advisory information.
- It does not include continuous advisory monitoring, automated vulnerability matching, a live vulnerability database or network scanning unless separately agreed.
- Patches and configuration changes are implemented by your teams or vendors through your change process.
What helps us get started
- Asset inventory with firmware and software versions
- Current list of tracked advisories or vulnerabilities
- Maintenance schedules and vendor support arrangements
Sensitive material is exchanged only after an engagement is agreed, using a method we agree with you — never through the website form.
Questions about OT Vulnerability Management
Why can't OT systems just be patched?
Patches may need vendor qualification, can require a process shutdown and may affect certified or validated configurations. That is why applicability checks and compensating controls matter.
What is a compensating control?
A measure that reduces the risk of a vulnerability when the primary fix cannot yet be applied, for example blocking the affected service at a firewall or restricting who can reach the device.
Do you provide vulnerability scanning?
No, not as part of this service. Active scanning of OT networks requires careful planning; this service works from asset data and published advisories.
