IEC 62443-4-2 Certified Industrial Ethernet Switches for Secure Industrial Networks
EtherWAN's industrial Ethernet switches are certified to IEC 62443-4-2 and developed in accordance with the IEC 62443-4-1 Security Development Lifecycle (SDL). Designed for energy, transportation, manufacturing, and critical infrastructure applications, these secure-by-design networking solutions help organizations build resilient industrial networks while preparing for evolving cybersecurity regulations such as the Cyber Resilience Act (CRA).
As Industry 4.0 and the Industrial Internet of Things (IIoT) continue to accelerate, the boundary between industrial control systems (IACS) and IT networks is becoming increasingly blurred. Industrial Ethernet switches are no longer simply communication devices—they have become a critical foundation for system reliability, operational continuity, and cybersecurity. Today, organizations are looking beyond performance and functionality, placing greater emphasis on products with verifiable, standards-based security capabilities.
IEC 62443-4-2 Certified Industrial Ethernet Switches from EtherWAN
Cybersecurity has been integrated into EtherWAN's product development process from the outset. Following the IEC 62443-4-1 Security Development Lifecycle (SDL), security requirements are incorporated throughout planning, design, testing, and maintenance to ensure products continue to evolve alongside emerging threats.
EtherWAN has achieved IEC 62443-4-2 certification or project-specific validation for multiple industrial Ethernet switch families, including:
Why Industrial Cybersecurity Is Becoming a Core Requirement
Driven by regulations such as the European Union's Cyber Resilience Act (CRA), cybersecurity is rapidly evolving from a value-added feature into a fundamental requirement for industrial networking equipment. Organizations operating in energy, transportation, manufacturing, and critical infrastructure sectors increasingly require products with verifiable and traceable cybersecurity capabilities to meet compliance, procurement, and operational demands.
Three Key Cybersecurity Challenges Facing Industrial Networks
During system deployment and long-term operation, asset owners and system integrators commonly face three challenges:
- Ensuring devices are built with security by design rather than relying solely on feature claims.
- Providing independent third-party validation to support procurement, project acceptance, and regulatory audits.
- Maintaining cybersecurity resilience throughout the product lifecycle as new threats continue to emerge.
As industrial environments become increasingly interconnected and complex, standardized cybersecurity capabilities have become essential for reducing risk and improving network reliability.
Benefits of IEC 62443-4-2 Certified Industrial Ethernet Switches
IEC 62443-4-2 is a component-level cybersecurity standard within the IEC 62443 framework for industrial automation and control systems. Certification is independently validated by an accredited third-party certification body (CB), DEKRA (DEKRA Certification B.V.), Third-party certification verifies that devices meet security requirements for authentication, access control, system integrity, data confidentiality, and secure communications.
IEC 62443-4-2 certified products help organizations:
- Reduce evaluation and deployment costs.
- Provide trusted third-party validation for procurement, acceptance, and compliance audits.
- Establish predictable and consistent security behavior across industrial networks.
- Improve operational reliability and reduce lifecycle cybersecurity risks.
- Prepare for future regulatory requirements, including the Cyber Resilience Act (CRA).
Building Industrial Networks with IEC 62443 Security Foundations
IEC 62443-4-2 certification represents more than product compliance. It demonstrates that cybersecurity has been considered throughout the entire lifecycle—from design and validation to maintenance and continuous improvement.
As digital transformation accelerates across smart manufacturing, IIoT, and critical infrastructure, IEC 62443-certified industrial Ethernet switches are becoming a key building block for reducing cybersecurity, operational, and regulatory risks while enabling secure and resilient industrial networks.
