IEC 62443, made manageable
One difficult process.
One connected workspace.
From zones and conduits to component assessment, technical gaps and reviewable evidence. Choose a stage to see why it matters and how ZeroGapOT helps.
IEC 62443, connected in one workspace
ZeroGapOT brings modelling, asset assessment, human review, gap tracking and exports into one workflow.
Define your zones and conduits
Build zones and conduits, place assets, record permitted flows and generate the architecture diagram from the same records.
Turn the model into requirements
Generate a draft CRS from recorded scope, architecture and targets. Review missing information and control the resulting document.
Connect risk decisions to security targets
Record your approved risk references, rationale and target profiles alongside zones and conduits. Scenario analysis and risk acceptance stay within your engineering process.
Assess assets against IEC 62443-4-2
Assess component requirements using configured AI assistance and manual review. Keep evidence, ratings, reviewer decisions and open actions connected to the asset.
Understand alignment and technical gaps
Compare component contributions with recorded targets. Use readiness views and dashboard metrics to trace gaps, dependencies and the evidence still needed.
Turn architecture context into security boundaries
Document zones, assets and permitted connections explicitly, then keep the diagram and assessment records together as the model changes.
Keep evidence ready for review
Centralise evidence and reviewer decisions, track actions and export governed data and reports. Outputs support assurance; they do not automatically establish compliance or certification.
