Energy cybersecurity solutions for utilities

IEC 62443 cybersecurity: proven industry standard support

IEC 62443 series is globally recognized as a standard for industrial automation and control systems cybersecurity. zenon is developed in accordance with the IEC 62443-4-1 standard and includes secure component interconnection, user authentication, and lifecycle management functionality. By adopting the IEC 62443 principles, zenon offers assurance that new infrastructure—and, where specifically validated, legacy systems—meets or aligns with international best practices, which is especially important for public utilities around the world. *Note that official certification to IEC 62443-4-1 applies to zenon versions developed since 2018, and alignment with IEC 62443-4-2 is present in zenon 15 and later.

NIS2 cybersecurity solutions: meeting European compliance

From a cybersecurity perspective, the NIS2 Directive of Europe raises the cybersecurity obligations on critical infrastructures such as the energy sector. zenon supports NIS2 compliance by delivering incident logging, automated alerting, and workflow-driven response capabilities. With enhanced monitoring and reporting features, zenon helps European utilities demonstrate compliance with NIS2 and maintain business resilience in a changing threat environment.

NIST cybersecurity frameworks: USA standards for critical infrastructure

The most notable security frameworks offered by the U.S. NIST agency are the NIST SP 800-53 (security controls) and the NIST SP 800-82 (OT/ICS security), which are widely adopted. The capabilities of zenon—configurable user access permissions, strong security logging, and the ability to install a hardened version of the zenon Software Platform—are designed to help utilities support their cybersecurity programs and meet these widely accepted U.S. standards. While zenon provides ample functionality to align compliance with NIST standards, full compliance is best achieved through careful configuration and integration with company policies.

Secure power system communication with IEC 62351

IEC 62351 defines security requirements for power system communications to ensure that data exchanged between control systems remains confidential and authentic. zenon’s integrated support for secure communication protocols, encryption, and digital signature validation enables utilities to deploy IEC 62351-compliant architectures from the substation to the control center.
