IEC 62443 is the internationally recognised security standard for industrial automation and control systems.

For organisations operating OT environments in EMEA, it has become the foundational framework against which compliance posture is increasingly assessed.

This eBook provides a practical guide to the standard, covering the zone and conduit model, security levels, and the specific requirements that apply to asset owners operating industrial networks. It addresses the challenges that make IEC 62443 compliance difficult in practice; legacy infrastructure, industrial protocol complexity, and the gap between IT security tooling and OT operational realities and sets out how organisations are building a structured, auditable approach to compliance without disrupting the environments they are trying to secure.

Download the eBook for a practical, compliance-ready guide to IEC 62443 and how to build a structured approach to OT security that stands up to audit.
