Auditor-grade evidence

Every closed plan
becomes an audit artifact.

Out of the box: TSA SD 1580-21-01, NIST CSF 2.0, NIST 800-82r3, IEC 62443, SOX, HIPAA, PCI DSS v4. Each closed remediation plan and OT compensating-control record is mapped to one or more control IDs and exported as both a machine-readable bundle and an auditor-ready PDF.

Industrial control systems standards

NIST SP 800-82r3

§5.1 ICS Risk Management — OT Safety Officer veto + compensating controls + reasoning traces.

§5.4 Zones & conduits — IEC 62443-style zone tagging enforced on every asset.

§6.2 Patch management for ICS — Maintenance-window enforcement · dual approval · canary peer · tested rollback.

§6.3.2 Identity controls — Inventory Insights identity_hygiene recommendations.

IEC 62443

2-1 Program management — Captured in Policy Studio · OPA bundles versioned.

2-3 Patch management — Enforced by policy gate · vendor advisories consumed · compensating controls deployed.

2-4 Service-provider requirements — Integrations health · scanner connector telemetry.

3-2 Security risk assessment — Captured in ChangeRiskScore + BusinessImpactProfile.

3-3 System security (incl. IAC-1) — OPA bundles · policy gate · audit log.

SOX · HIPAA · PCI & how evidence is produced

SOX §404

Change management evidence — every plan has approvals, rollback, executor identity, verifier record. Suitable for IT general controls testing.

HIPAA Security Rule

Where tenants carry PHI-adjacent systems. Same evidence pipeline tagged to §164.308 / §164.312 controls.

PCI DSS v4

For transit-payment systems (rail PCI environments). Maps to 6.3, 6.4, 11.3, 12.10.

Machine-readable bundle

JSON Lines with one record per evidence unit. Suitable for ingestion into GRC platforms (Archer, MetricStream, ServiceNow IRM).

Auditor-ready PDF

Generated by Compliance Reporter via ReportLab. Watermarked SIMULATED on demo tenants; clean on production. Control-by-control, with reasoning-trace excerpts and signed message IDs.
