IEC 62443 Industrial Control System Security Study 2026

Are you planning to certify an industrial control system, and not sure where to begin? IEC 62443 certification is a multi-phase process that demands precise preparation at every step. A missing document, an overlooked prerequisite, or an undocumented security test can stall your entire project before the evaluation even begins. This study was built by CCLab's evaluators to give you a clear, structured starting point, so you know exactly what's ahead before the clock starts ticking. This publication was updated in 2026 to reflect the latest EU regulatory deadlines, including the Cyber Resilience Act (CRA) full application date and the EU Machinery Regulation enforcement requirements.

In this IEC 62443 Industrial Control System Security Study, you’ll learn:

• How IEC 62443 fits into the EU regulatory landscape. From the Cyber Resilience Act to the EU Machinery Regulation, understand which rules apply to your products and when.
• The exact sequence of certification phases. Development, self-assessment, evaluation, certification—what happens in each phase and what you must prepare before moving forward.
• The role your organization plays in the standard. Whether you are an asset owner, system integrator, or product manufacturer, your responsibilities differ significantly.
• Why built-in security is no longer optional. Products can no longer rely on external countermeasures. Discover what independent security capability means for your design process.
• What evaluators audit on-site. The specific artifacts, documentation, and process evidence that must be ready before a CCLab evaluator walks through your facility.
• How to achieve international market access. Learn how IECEE CB Scheme certificates issued after evaluation open doors beyond the EU, and what that means for your certification strategy.

Why Download This IEC 62443 Study?

IEC 62443 certification is not a single test, it's a structured process with hard prerequisites and mandatory documentation at every stage. This study is the shortcut that turns a complex standard into a clear action plan.

• Built on real evaluation experience. Compiled by CCLab's certified evaluators, the same team that has guided 140+ clients and completed 200+ successful certification projects.
• Covers what the standard text doesn't spell out. The prerequisite dependencies, documentation requirements, and on-site audit expectations that first-time applicants consistently underestimate.
• Updated for 2026 EU deadlines. The Cyber Resilience Act, the Radio Equipment Directive, and the EU Machinery Regulation are already in motion. Know exactly how much time you have, and what compliance means for your product.
• Applicable across all three stakeholder roles. Whether you build, integrate, or operate industrial control systems, this study maps out your specific responsibilities under the standard.
