AI is arriving in OT security tools quickly. Used well, it removes repetitive work from small teams. Used carelessly, it introduces new risks into environments where mistakes have physical consequences.
Where AI genuinely helps
The best uses today are assistive and reversible: AI prepares, a person decides.
- Explaining requirements. Turning a dense control requirement into plain language for an engineer.
- Drafting findings. Converting assessment notes into a consistent finding with observation, evidence and recommendation, ready for review.
- Triaging advisories. Summarizing a vendor advisory and highlighting which product versions are affected, so an analyst can confirm applicability against the asset inventory.
- Summarizing posture. Producing a first draft of a management summary from structured assessment data.
These save hours without touching a control system.
Where AI needs strict guardrails
- Anything that changes the process. Configuration changes, firewall rules or setpoints must go through change control and human approval.
- Data leaving the site. Architecture drawings and asset lists are sensitive. Know where an AI service processes and stores data.
- Confident but wrong answers. Language models can produce plausible errors. Answers should be grounded in your own records and cite their source.
- New attack surface. AI features connected to OT data become targets themselves and belong in your risk assessment.
A simple policy for OT teams
- AI may draft, summarize and explain; it may not execute changes in OT.
- Every AI-generated finding or recommendation is reviewed by a named person.
- Sensitive OT data is only processed by approved services with known data handling.
- AI features are included in the OT risk assessment and policies.
Regulation is catching up
The EU AI Act and frameworks such as NIST's AI Risk Management Framework are shaping expectations for how AI is governed. For OT teams, the practical message is consistent: keep humans accountable and document how AI is used.
Our approach
The Vista AI Assistant, in development, follows these principles: it drafts and explains from your own records, and people make every decision.
