What is IEC 62443?
IEC 62443 is an international series of standards focused on cybersecurity in industrial automation and control systems (IACS), providing a risk-based framework that has become the technical baseline for EU NIS2 compliance.
Technical Definition: An international series of standards focused on cybersecurity in industrial automation and control systems (IACS). IEC 62443 defines security requirements at different levels: from security management processes to specific technical requirements for components, systems and network architectures.
Why it matters: With NIS2 making OT cybersecurity a legal requirement across the EU, IEC 62443 has become the technical baseline for compliance. It provides a structured, risk-based approach to securing building and industrial systems.
HubMind’s view: We use IEC 62443 as the technical specification for OT security in every project. Security designed around this standard provides both legal compliance and genuine operational protection.
