Mitsubishi Electric to Acquire Nozomi Networks to Improve Industrial Cyber Defenses
Strategic Acquisition Accelerates Industrial Automation Security
Mitsubishi Electric Corporation has signed a definitive agreement to acquire Nozomi Networks, a global leader in OT, IoT, and CPS cybersecurity. Therefore, this move signals a deeper commitment to securing industrial automation, PLC, DCS, and control systems worldwide. After closing, Nozomi Networks will operate as a wholly owned subsidiary while retaining operational independence.
Building on an Established Partnership in OT and IoT Security
This acquisition builds on a strong existing relationship. In March 2024, Mitsubishi Electric joined Nozomi Networks’ USD 100 million Series E funding round. Moreover, both companies have already collaborated on technology development and go-to-market initiatives, reducing integration risks and strengthening execution confidence.
Expanding AI-Powered, Cloud-First Cybersecurity Capabilities
Nozomi Networks brings an AI-driven, cloud-first cybersecurity software platform with proven scalability. As a result, Mitsubishi Electric gains advanced threat detection, network visibility, and contextual analytics tailored for industrial control systems. These capabilities align closely with modern factory automation and critical infrastructure protection needs.
Leveraging Deep Industrial Automation Experience
Mitsubishi Electric contributes more than a century of expertise in industrial automation, energy systems, transportation, and building technologies. In addition, its global presence enhances Nozomi’s ability to scale cybersecurity solutions across diverse OT environments, including legacy PLC and DCS architectures.
Shared Vision for Data-Driven Cyber Defense
Both companies emphasize the value of OT and IoT data combined with artificial intelligence. However, the real strength lies in context-aware security. By understanding industrial processes, control logic, and operational baselines, cybersecurity tools can deliver more accurate detection and faster incident response.
Commitment to Customers, Partners, and Open Ecosystems
Nozomi Networks will maintain its brand, leadership team, and partner-first business model. Therefore, customers can expect continuity across product roadmaps, integrations, and third-party ecosystem support. This approach is critical for heterogeneous industrial environments where multi-vendor compatibility remains essential.
Leadership Perspectives on Digital Transformation and Resilience
Mitsubishi Electric leadership highlights the opportunity to co-create new digital services that improve security, efficiency, and operational resilience. Similarly, Nozomi Networks’ executive team stresses that daily customer engagement will remain unchanged, reinforcing trust during the transition.
Closing Timeline and Global Operations Continuity
The transaction is expected to close in the fourth quarter of 2025. Upon completion, Nozomi Networks will keep its headquarters in San Francisco, with research and development continuing in Mendrisio, Switzerland. As a result, global innovation pipelines and customer support structures remain stable.
Industry Analysis: Why This Deal Matters for Control Systems
From an industry perspective, this acquisition reflects a broader trend. Industrial automation vendors increasingly integrate cybersecurity directly into control systems. In practice, tighter alignment between automation engineering and security operations reduces downtime, improves compliance with standards like IEC 62443, and strengthens cyber resilience.
Practical Applications and Solution Scenarios
In real-world deployments, manufacturers can combine Mitsubishi Electric automation platforms with Nozomi’s OT security to monitor PLC traffic, detect anomalous control commands, and protect DCS networks. Utilities can apply the same approach to secure substations and grid control systems, while transportation operators can improve visibility across signaling and control networks.
