Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed a new operational technology (OT) security solution for industrial equipment, leveraging the world-class OT cybersecurity technologies of Nozomi Networks, Inc., a U.S.-based company that became a wholly owned subsidiary of Mitsubishi Electric in January 2026. The solution will enable industrial equipment manufacturers to implement stronger cybersecurity measures and end users to operate facilities and equipment more safely, securely and reliably. The solution will launch commercially as an extension of Nozomi Arc™ during the fiscal year ending in March 2028.
In recent years, as IoT adoption and digital transformation have accelerated in the manufacturing and critical infrastructure sectors, OT cybersecurity has become increasingly important for ensuring business continuity. In addition, compliance with regulations and standards, such as the European Cyber Resilience Act, is driving increased demand for stronger cybersecurity measures in industrial equipment and the systems in which such equipment is deployed. However, OT environments typically consist of diverse equipment and devices, making it difficult to monitor the status of individual assets, their communications, and abnormal behavior. As a result, addressing cyber threats originating from industrial equipment has become a significant challenge.
The new solution addresses these challenges by integrating Nozomi Arc’s monitoring capabilities directly into industrial equipment, including Mitsubishi Electric’s controller products, to provide USB monitoring, malware detection, quarantine and removal, and software management.
