An IEC 62443-4-2 certified Ethernet switch is an industrial network device designed to meet international cybersecurity requirements for secure OT communication. It helps protect critical infrastructure by supporting security functions such as user authentication, access control, secure configuration, event logging, and vulnerability management. For industrial automation, transportation, energy, and utility networks, IEC 62443-4-2 switches provide a stronger foundation for resilient, compliant, and secure Ethernet connectivity.
EtherWAN offers IEC 62443-4-2 certified industrial Ethernet switches for demanding OT environments where cybersecurity, uptime, and long-term network reliability are essential. These switches are built for industrial automation, transportation, energy, utilities, and other critical infrastructure networks that require secure and resilient connectivity.
IEC 62443-4-2 for Secure OT Networks
IEC 62443-4-1 vs IEC 62443-4-2: What's the Difference?
IEC 62443-4-1 and IEC 62443-4-2 are both part of the IEC 62443 cybersecurity standards for industrial automation and control systems, but they address different areas. IEC 62443-4-1 focuses on the supplier's secure product development lifecycle, while IEC 62443-4-2 defines the technical security requirements that individual IACS components, such as industrial Ethernet switches, should provide.| Standard | Focus | What It Means |
|---|---|---|
| IEC 62443-4-1 | Secure development lifecycle | Defines how products are securely designed, developed, tested, released, maintained, updated, and supported throughout the product lifecycle. |
| IEC 62443-4-2 | Technical security requirements for components | Defines the cybersecurity capabilities built into the switch itself, such as authentication, access control, system integrity, data confidentiality, event response, and resource availability. |
Why Choose IEC 62443-4-2 Certified Ethernet Switches?
Industrial Ethernet switches are critical connection points in OT networks. A misconfigured or unauthorized switch can affect production lines, transportation systems, energy facilities, and other mission-critical operations.
IEC 62443-4-2 certification helps system integrators and asset owners verify that network components support essential security functions, making it easier to specify secure, compliant, and resilient OT infrastructure.
| Requirement Area | Why It Matters for OT Networks |
|---|---|
| Access Control | Helps reduce unauthorized access to industrial network devices. |
| System Integrity | Supports secure configuration, firmware management, and reliable device operation. |
| Event Visibility | Helps operators identify abnormal activity or configuration changes. |
| Network Resilience | Supports stable communication for production, energy, transportation, and critical infrastructure networks. |
| Compliance Support | Helps system integrators and asset owners specify certified components for cybersecurity-sensitive OT projects. |
