IEC 62443


Achieve certification to IEC 62443  

As industrial systems become increasingly interconnected and digitised, the need for robust cybersecurity measures becomes ever more important. Industrial control systems are particularly vulnerable to cyber threats, considering their critical role in managing essential and often critical operations.  

To support organisations to identify and minimise threats, the International Electrotechnical Commission (IEC) introduced the IEC 62443 series of standards. Our specialist certification team is on hand to help you achieve and maintain certification to IEC 62443.   

What is IEC 62443?

As the digitalisation of industrial processes accelerates, so do the cybersecurity risks to industrial control systems. The cyber integrity of industrial environments and Operational Technology (OT) has therefore become a top priority for governments and asset owners across the world.  

IEC 62443 is a comprehensive series of international standards designed specifically for industrial automation and control systems security. It provides a systematic approach to identifying and mitigating cybersecurity risks throughout the entire lifecycle of industrial control systems. These standards are applicable to various industries, including manufacturing, energy, transportation and more. 

The set of standards takes a holistic approach to industrial cybersecurity, taking into account both technical and organisational aspects. It covers a wide range of security measures including risk assessment, security policies, security development, system integration, ongoing maintenance and in the near future entire locations. By adopting a comprehensive framework, IEC 62443 aims to address vulnerabilities at every stage of the industrial control system's lifecycle. Like many global standards, it provides a roadmap to success and certification helps minimise the risk of cyber attacks on industrial control systems.
