Who it applies to

Asset owners, system integrators, and product suppliers in OT/ICS environments.

Audit / certification status

Continuous evidence pipeline available; audit support included for all customers.

What it requires

What IEC 62443 actually requires.

These are the obligations a regulated entity owes — the things an assessor or supervisor will ask about.

01

Security Levels (SL-1 through SL-4) per zone and conduit.

02

Component-level security requirements (62443-4-2).

03

Development lifecycle security (62443-4-1).

How Safeguard maps to it

Pre-mapped controls. Continuous evidence.

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.

Evidence we produce

Artifacts your auditor accepts.

Each evidence artifact is signed and timestamped. Auditors can verify integrity without trusting Safeguard.

Related frameworks

One evidence base. Many regulators.

These frameworks share substantial control overlap with IEC 62443. Customers running one assessment typically satisfy the others with the same evidence base.
