TAIPEI, Taiwan, July 22, 2026 — Moxa Inc., a leader in industrial communications and networking, proudly announced ISA/IEC-62443-4-2 Security Level 2 (SL2) certification under the International Electrotechnical Commission for Electrical Equipment (IECEE) Certification Body Scheme for its UC Series 64-bit Arm-based computers that run Moxa Industrial Linux 4 (MIL4) Secure OS. 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 cybersecurity 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 cybersecurity maturity of the entire supply chain. An IEC 62443-4-2 certified computer, for example, helps equipment manufacturers and system integrators demonstrate that cybersecurity 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 organization in the field of testing, inspection and certification, under the IECEE CB Scheme.
“ISA/IEC 62443-4-2 provides a clear and internationally recognized framework for verifying the cybersecurity 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 cybersecurity requirements. We are honored 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.”
ISA/IEC 62443-4-2 certification demonstrates secure-by-design focus at product development
As factories, energy and oil & gas facilities become increasingly software-defined and interconnected, operators require a secure foundation for deploying applications, virtualizing 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 cybersecurity 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 minimize unplanned security-related costs.
“With an ISA/IEC 62443-4-2 SL2 certified computer, our customers can start their projects with a pre-validated cybersecurity foundation, allowing engineering teams to focus on application deployment and operational resilience,” said Casper Yang, vice president, Product Business Group at Moxa. "Our standardized, 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.”
Our ISA/IEC 62443-4-2 SL2 certified UC Series computers offer a secure-by-design foundation with MIL Secure OS. They also feature hardware root-of-trust authentication and Secure Boot to prevent system tampering and cyberattacks, and auto-recovery and dual-system for maximum uptime, alongside network protection to minimize the attack surface.
