The industrial automation and control systems security standard family — the OT equivalent of ISO 27001.
Asset owners, system integrators, and product suppliers in OT/ICS environments.
Continuous evidence pipeline available; audit support included for all customers.
These are the obligations a regulated entity owes — the things an assessor or supervisor will ask about.
Security Levels (SL-1 through SL-4) per zone and conduit.
Component-level security requirements (62443-4-2).
Development lifecycle security (62443-4-1).
Each requirement above is bound to live telemetry — not screenshots. The mapping below is what your auditor or regulator sees.
OT asset inventory with zone/conduit classification.
Component-level security requirement evidence.
Each evidence artifact is signed and timestamped. Auditors can verify integrity without trusting Safeguard.
Zone/conduit diagram with SL targets.
62443-4-1 lifecycle evidence.
These frameworks share substantial control overlap with IEC 62443. Customers running one assessment typically satisfy the others with the same evidence base.
Bring the framework. We'll walk the controls with you — section by section, evidence packet by evidence packet, with the regulators you actually have to answer to.
