[OT Sec] ISA/IEC 62443 Certification Program: A Global Standard and Training Program for Industrial Cybersecurity Experts

Overview of the ISA/IEC 62443 Certification Program

The ISA/IEC 62443 certification program is an internationally recognized comprehensive training initiative designed to develop professionals with the knowledge and skills necessary to ensure the security of Industrial Automation and Control Systems (IACS). Based on the ISA/IEC 62443 standards—an internationally agreed-upon series of standards focusing on automation cybersecurity—the program addresses all phases of the system lifecycle, including assessment, design, implementation, and maintenance. It is closely aligned with global cybersecurity frameworks and forms an integral part of governmental and industrial efforts to mitigate cyber threats in operational environments.

This program is particularly beneficial for professionals in IT and control system security roles who need to understand the terminology, concepts, and methodologies of industrial cybersecurity. Participants who successfully complete the training courses and pass the associated exams receive certifications that validate their expertise in key areas of IACS cybersecurity. Furthermore, those who complete all certifications are awarded the prestigious title of ISA/IEC 62443 Cybersecurity Expert.
