Mitsubishi Electric is moving to acquire Nozomi Networks in a deal that strengthens its industrial cybersecurity capabilities and expands its role in digital transformation. The Japanese technology giant announced plans to complete the acquisition in Q4 2025, with Nozomi set to operate as an independent, wholly owned subsidiary. Nozomi will continue to support its global customer base without changes to its roadmap, operations, or partnerships.
The acquisition builds on Mitsubishi Electric’s March 2024 participation in Nozomi’s $100 million Series E funding round. Mitsubishi brings a century of industrial expertise across factory automation, energy systems, and infrastructure, while Nozomi delivers AI-driven security for operational technology (OT), IoT, and cyber-physical systems (CPS). Together, the companies aim to create integrated services that enhance resilience and efficiency in critical infrastructure sectors.
Nozomi Networks was founded in 2013 in Mendrisio, Switzerland, by Andrea Carcano and Moreno Carullo, as cyberattacks like Stuxnet and Industroyer exposed vulnerabilities in industrial control systems (ICS). The company developed a platform for real-time visibility across IT and OT environments, helping enterprises detect anomalies, prevent intrusions, and mitigate operational risk.
• Mitsubishi Electric will acquire Nozomi Networks in Q4 2025
• Nozomi will remain an independent subsidiary post-acquisition
• Nozomi specializes in OT, IoT, and CPS cybersecurity with an AI-driven platform
• Mitsubishi previously invested in Nozomi’s $100M Series E round in March 2024
• Founded in 2013, Nozomi emerged in response to rising ICS cyber threats like Stuxnet and Industroyer
“By combining Nozomi’s strengths with Mitsubishi Electric’s extensive OT capabilities, we can create powerful new services to enhance security, efficiency, and resilience for customers,” said Satoshi Takeda, Senior Vice President and Chief Digital Officer at Mitsubishi Electric.
🌐 Analysis: Mitsubishi Electric’s acquisition underscores a broader industry trend of industrial conglomerates deepening their cybersecurity portfolios to safeguard digital transformation initiatives. Siemens, Honeywell, and Schneider Electric have all invested heavily in OT security as factories, energy systems, and transportation networks become increasingly connected. Nozomi’s independent structure within Mitsubishi suggests a strategy to preserve agility while scaling globally under a larger industrial brand.
