Nozomi Networks Inc. announced the OT and IoT security sensor that runs embedded in Mitsubishi Electric programmable logic controllers (PLCs). With Arc Embedded, security and operations teams gain previously unavailable visibility at the process level of their industrial automation equipment and field assets as well as the ability to analyze and deter process level threats and malicious user activity without impacting current resources or disrupting mission critical networks. As a result, organizations benefit from greater operational resilience and uptime, reduced cyber risk, and better compliance.

Arc Embedded transforms existing industrial control systems into secure-by-design assets, offering a fully integrated security layer from an independent vendor that delivers robust, comprehensive protection for today’s in-production systems. The newest component in Nozomi Networks’ AI-powered OT/IoT security platform, Nozomi Arc Embedded in Mitsubishi Electric PLCs makes it possible for organizations to monitor east-west activity in order to detect and respond to cyber incidents at the PLC level before they can do harm or escalate across the entire industrial operations environment. This proactive approach strengthens operational resilience, reduces downtime, protects critical infrastructure, and maintains process integrity. Arc Embedded on Mitsubishi Electric PLCs delivers:
Real-time visibility and security from the network endpoint to the manufacturing floor to enhance data integrity, more accurately detect PLC anomalies, and detect unauthorized access (intrusions).
AI-powered protection to provide continuous monitoring for real-time learning, faster responses to security incidents and more robust detection of known and unknown vulnerabilities.
Innovative visibility and protection for devices connected to the PLC “backplane” to understand module health and status, normal and abnormal communications patterns, all configuration changes, and firmware integrity.
Arc Embedded is available now for Mitsubishi Electric iQ-R series PLCs via a subscription-based model, available from Mitsubishi Electric, Nozomi Networks, and an extensive global network of Nozomi Networks channel partners.
