TÜV Rheinland has officially certified the CIP Security specification for meeting the rigorous IEC 62443-4-2 cybersecurity requirements. This certification validates the technology for manufacturers developing EtherNet/IP products.
Why it matters
This certification simplifies the compliance path for manufacturers while addressing essential secure-by-design requirements under the European Union's Cyber Resilience Act. It ensures that industrial systems can better defend against attackers with moderate resources and IACS-specific skills.
The certification grants a Security Level 3 rating, which protects against intentional violations by attackers with moderate resources. The standard utilizes TLS and DTLS encryption to provide data integrity, authentication, and confidentiality.
The players
TÜV Rheinland
This global testing, inspection, and certification organization provides technical safety and quality evaluations for products and systems.
ODVA
This international trade and standards development organization oversees the specifications and ecosystem for EtherNet/IP technologies.
The details
CIP Security functions as an application-layer network extension for EtherNet/IP environments. By meeting international standards, it provides a unified framework for data confidentiality in industrial automation.
Timeline
October 30, 2026: The achievement of this certification was announced by ODVA.
The Tech Race
This development aligns industrial communication protocols with the security mandates established by the European Union's Cyber Resilience Act. It marks a significant shift toward standardized, secure-by-design architecture in a sector previously fragmented by diverse vendor-specific security approaches.
Manufacturers can now leverage this certified specification to expedite compliance with new regulatory security mandates. This standardization reduces the technical burden on developers while increasing the baseline protection for industrial automation networks.
The takeaway
Achieving this certification helps bridge the gap between legacy industrial design and modern, secure digital infrastructures. Manufacturers should prioritize these updated specifications to ensure future compatibility with global cybersecurity regulations.
