Nozomi Networks, a provider of OT and IoT security, has unveiled the industry’s first OT and IoT security sensor embedded within Mitsubishi Electric programmable logic controllers (PLCs).
The introduction of Arc Embedded grants security and operations teams unprecedented visibility at the process level of their industrial automation equipment and field assets. This capability allows for the analysis and mitigation of process-level threats and malicious activity without affecting existing resources or disrupting crucial networks. Consequently, organisations experience enhanced operational resilience and uptime, reduced cyber risk, and improved compliance.
“We’re honoured to partner with innovator and industry leader Mitsubishi Electric to bring Arc Embedded to their PLCs,” said Andrea Carcano, Co-Founder and CPO, Nozomi Networks. “Arc Embedded can transform how CISOs manage and protect critical infrastructure, extending security to and through industrial control systems, down to the field assets they manage.”
“Mitsubishi Electric is the perfect partner for this initiative, thanks to its passion for innovation and an unmatched understanding of automation,” added Carcano. “Through our joint work, customers in a variety of industries can feel confident deploying Arc Embedded in Mitsubishi Electric PLCs, strengthening security all the way to the physical process. This is a revolutionary approach that makes it possible to extend in-depth real-time monitoring of assets, network traffic, anomaly detection, and threat identification directly to process controls. Ultimately, it improves the safety, security, and reliability of the automation processes we depend upon and sparks the imagination for what’s possible when advanced security is embedded at the device level.”
“Solutions that provide robust OT security and continuous system operation are a priority in Mitsubishi Electric’s ongoing digital transformation,” said Kunihiko Kaga, Mitsubishi Electric’s Representative Executive Officer and Industry & Mobility Business Area Owner. “Combining Mitsubishi Electric’s manufacturing-control and information-system security technologies with Nozomi Networks’ visualisation and intrusion-detection technologies, allows us both to contribute to a safer, more secure and more sustainable society.”
A PLC is an industrial digital computer designed to automate manufacturing processes, ensuring high reliability and ease of programming. PLCs are widely used across various industries, enhancing operational efficiency through real-time processing and control in challenging environments. Mitsubishi Electric’s MELSEC iQ-R series PLCs, among the most advanced globally, facilitated the development of this new embedded security solution.
The PLC market is projected to reach $22 billion by 2030 as more industries adopt and expand automation, driving the need for enhanced control-level cybersecurity. Recent advisories from the Cybersecurity and Infrastructure Security Agency (CISA) on attempted PLC exploits highlight the potential risks, including production shutdowns or public safety crises.
Arc Embedded transforms existing industrial control systems into secure-by-design assets, offering a fully integrated security layer from an independent vendor. This robust protection is now part of Nozomi Networks’ award-winning, AI-powered OT/IoT security platform. For the first time, organisations can monitor east-west activity to detect and respond to cyber incidents at the PLC level before they cause harm or escalate across industrial operations. This proactive approach strengthens operational resilience, reduces downtime, protects critical infrastructure, and maintains process integrity.
