AI-assisted IEC 62443 assessment & assurance

Align your OT estate to IEC 62443.
Prove it with evidence.

Enter your assets, zones and conduits once. ZeroGapOT generates the architecture and turns IEC 62443-4-2 assessment results into dashboards, alignment insights and report outputs—from one asset to a whole system. Use AI assistance or manual review, with less time spent assembling the results.

Deployment & scope

Your infrastructure.
An explicit assessment basis.

ZeroGapOT is self-hosted. Deterministic assessment supports disconnected operation. Optional AI review depends on entitlements, the deployment policy and configured provider. External providers may receive assessment evidence when enabled.

The current platform records risk criteria, references and security targets. Use your approved engineering process for scenario analysis, risk scoring and residual-risk acceptance. Report approval is not certification.
