IEC 62443 – Industrial Automation and Control System Cybersecurity Essentials Training by Tonex

Across modern plants and critical infrastructure, digitalization has fused IT and OT into a single, high-stakes environment. This course immerses participants in the practical language and structure of IEC 62443, translating standards into day-to-day engineering and governance actions. You’ll learn how to scope zones and conduits, specify security requirements, and verify compliance without slowing operations. Cybersecurity is central: you’ll map threats to IEC 62443 controls, close gaps in vendor chains, and embed defense-in-depth across industrial assets. Expect clear methods for risk assessment, secure integration, and lifecycle assurance so that safety, reliability, and cyber resilience advance together in the plant.
