Verified security architecture

This milestone marks a significant shift from a single certified product to establishing a consistent security baseline for an entire product line, wherein our customers benefit from a verified security architecture across both data gateways and 5G edge-computing platforms.

Moxa successfully launched the world's first IEC 62443-4-2 certified host device, the UC-8200 Series Arm-based computers, in 2023. Building on this accomplishment, the entire UC Series 64-bit Arm-based computer portfolio is now certified to offer our customers a trusted operational technology (OT) computing platform based on a strong and secure foundation.

From voluntary best practice to mandatory gatekeeping

Currently, multiple regulatory timelines are simultaneously in effect across regions for cyber security compliance. The EU Cyber Resilience Act (CRA) is expected to be fully implemented by the end of 2027, while Japan launched JC-STAR IoT Security Labeling Scheme in 2025. Although these regulations vary in name and the applicable region, their technical core is closely based on the IEC 62443 standards.

In today’s market, customers face increasing global scrutiny, not only regarding the machines or systems they purchase but also concerning the cyber security maturity of the entire supply chain. An IEC 62443-4-2 certified computer, for example, helps equipment manufacturers and system integrators demonstrate that cyber security is integrated into the platform from the beginning, thereby reducing project risk, speeding up the qualification processes, enhancing customer trust, and improving readiness for regulatory requirements and critical infrastructure needs. The certification was conducted by DEKRA, the world’s largest independent, non-listed expert organisation in the field of testing, inspection, and certification, under the IECEE CB Scheme.

“IEC 62443-4-2 provides a clear and internationally recognised framework for verifying the cyber security capabilities of industrial automation and control system components,” said Maxi Tsai, general manager of DEKRA APAC DTS and onward security. “Moxa’s UC Series 64-bit Arm-based computers have achieved IEC 62443-4-2 Security Level 2 certification, demonstrating that the products have been assessed against defined international cyber security requirements. We are honoured to have supported Moxa through this certification process and will continue helping industrial equipment manufacturers strengthen product cyber resilience and market trust through our trusted certification services.”

Secure-by-design focus

As factories, energy, and oil and gas facilities become increasingly software-defined and interconnected, operators require a secure foundation for deploying applications, virtualising payloads, and leveraging edge intelligence. With the IEC 62443-4-2 SL2 certified UC Series, featuring the MIL Secure OS, customers choose a computer without compliance risks. The computers provide industrial-grade cyber security with secure-by-design features, hardening guides, and diagnostic tools. In addition, a 10-year security commitment ensures long-term security maintenance and reduces life cycle risks, helping operators simplify ongoing operations and minimise unplanned security-related costs.

“With an IEC 62443-4-2 SL2 certified computer, our customers can start their projects with a pre-validated cyber security foundation, allowing engineering teams to focus on application deployment and operational resilience,” said Casper Yang, vice president, product business group at Moxa. "Our standardised, secure-by-design platform provides customers with a consistent security baseline backed by a 10-year OS support, be it for compact gateway to high-performance 5G edge platforms. With our certified UC Series portfolio, customers should never have to compromise on specifications to stay compliant, or risk compliance to get the specifications they need. We enable them to reduce the effort required for security design, validation, and compliance, and instead focus their resources on accelerating solution development and time-to-market.”
