Reach IEC_62443 readiness without rebuilding your policy programme
IEC 62443 (formerly ISA-99) is the leading international cybersecurity standard for Industrial Automation and Control Systems (IACS). Multi-part series covering general concepts, policies + procedures, system requirements + component requirements. Risk-based zone + conduit model + Security Levels (SL 1-4). Used by OT product vendors (62443-4-1/4-2) + asset owners (62443-2-1/3-2/3-3). Increasingly required in OT procurement; certifiable by IECEE. NIST SP 800-82 + ENISA + national CSIRTs align with 62443. Quick Policy maps IEC_62443 into the policy families, controls, and evidence your team needs — and keeps it current between audits.

Why IEC_62443 matters for your operating model
IEC_62443 doesn't just dictate document templates — it shapes which controls auditors test, what evidence they ask for, and which gaps surface first during diligence. Getting it wrong creates renewal slippage, audit findings, and stalled customer deals.
- • Issued by International Electrotechnical Commission with global recognition.
- • Directly shapes policy families including Information Security, Operational Technology — these are the artefacts assessors open first.
- • Common artifacts include Policy.
- • Obligation model: Voluntary — meaning you need defensible reasoning for in-scope vs out-of-scope decisions, not just signed policies.
How Quick Policy helps you stand up IEC_62443
The platform turns IEC_62443 from a PDF of requirements into a live operating model — policies, training, evidence, and audit-export packs that update in lock-step when the standard or your business changes.
- • Adopt IEC_62443 once and Quick Policy seeds the right policy families (Information Security, Operational Technology) with applicability rationale your auditor can follow.
- • Common artifacts include Policy.
- • Review cadence is enforced at ~365 days so policies don't silently expire ahead of recertification.
- • Standard updates (IEC_62443 revisions, errata, regulator guidance) trigger an applicability re-check across your active policies — not a full rewrite.
