Learn More About IEC 62443-4-2 Certified Computers

IEC 62443-4-2 is the part of the IEC 62443 series that focuses on technical security requirements for industrial automation and control system components. When applied to an industrial computer, it indicates that the product has been assessed against recognised component-level cybersecurity requirements, helping show that security has been considered as part of the device itself rather than only around it.

A certified computer can be a strong option where cybersecurity forms part of the wider specification, approval process, or end-user requirement. Certification helps provide added confidence that the device has been independently assessed against recognised technical security criteria, making it relevant for industrial applications where secure connectivity, long-term resilience, and stronger product-level assurance all matter.

Start by matching the platform to the application itself, including processor performance, I/O, network connectivity, expansion needs, mounting style, temperature range, and power requirements. From there, confirm that the specific certified model also fits the cybersecurity expectations of the project. The right choice is usually the system that balances practical deployment needs with the level of product-level security assurance required.

In most industrial systems, cybersecurity depends on more than one device type. A certified computer can help strengthen the compute or control layer, while certified switches, routers, and other networking products can help support the wider communications infrastructure around it. Looking at both together can help create a more consistent approach across the overall system. You can also explore our IEC 62443-4-2 networking devices here.
