Why IEC 62443 — Industrial Automation + Control Systems Security matters for your operating model

IEC 62443 — Industrial Automation + Control Systems Security 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.
