IEC 62443-4-2 SL2 Certified Networking

Browse IEC 62443-4-2 SL2 certified networking devices designed to support stronger cybersecurity at the component level across industrial Ethernet networks. IEC 62443-4-2 defines technical security requirements for IACS components, including network components, and Security Level 2 is generally associated with protection against intentional violation using simple means, low resources, generic skills, and low motivation. Our range includes certified networking products such as Ethernet switches and other industrial network devices for applications where cybersecurity, reliability, and industrial deployment suitability are all important.

Learn More About IEC 62443-4-2 SL2 Networking Devices

IEC 62443-4-2 is the part of the IEC 62443 series that sets out technical security requirements for industrial automation and control system components, including embedded devices, host devices, software applications, and network components. It is used to assess whether individual products meet defined cybersecurity requirements at the component level.

Within the IEC 62443 framework, Security Level 2 is generally understood as a level intended to protect against intentional violation using simple means with low resources, generic skills, and low motivation. For buyers, that makes SL2 certification a useful indicator that a device has been assessed against a recognised baseline of industrial cybersecurity requirements beyond basic product claims alone.

These products are typically chosen when industrial network security is an important part of system design and product selection. Certification can help provide added confidence that a device has been assessed against recognised technical security requirements, making it relevant for projects where secure network infrastructure, policy alignment, or cybersecurity-focused procurement are key considerations.

No. IEC 62443-4-1 and IEC 62443-4-2 are related but different. IEC 62443-4-1 focuses on secure product development lifecycle requirements, while IEC 62443-4-2 focuses on the technical security requirements of the component itself. They are not interchangeable.
