IEC 62443: The international cyber security standard for Industry 4.0
Industrial plants are increasingly vulnerable to cyberattacks, with hackers exploiting weak points to disrupt operations. To address these risks, EU laws such as the NIS 2.0 Directive, Radio Equipment Directive (01.08.25) or Cyber Resilience Act (11.12.27) mandate the implementation of Cyber Security best practices and security certifications especially for critical infrastructures. The globally recognized IEC 62443 standard provides already now a framework for protecting Industrial Automation and Control Systems (IACS), helping operators, integrators, and manufacturers enhance the availability, integrity, and confidentiality of their systems and components and fulfilling most parts of the laws.
TÜV Informationstechnik (TÜV NORD GROUP) supports organizations in achieving compliance with IEC 62443 through services such as scoping, audits, supplier evaluations, and certification. These services help companies strengthen their cybersecurity posture, ensuring their systems are resilient against threats and aligned with the requirements for secure Industry 4.0 solutions
