The Tokyo-based electronic equipment manufacturer will tap San Francisco-based Nozomi’s capabilities in OT, IoT and cyber-physical system security to enhance visibility, threat detection and efficiency in industrial systems. Mitsubishi will integrate Nozomi’s AI-powered cybersecurity technology into its broader Serendie digital platform to transform industrial operations through secure data and analytics.
“We are excited to welcome Nozomi to the Mitsubishi Electric family. Their cutting-edge OT security technology and rapid development philosophy have earned them a strong reputation,” Mitsubishi Electric Senior Vice President Satoshi Takeda said in a statement. “By combining Nozomi’s strengths with Mitsubishi Electric’s extensive expertise and capabilities in OT, I believe we can achieve even more.”
Nozomi Networks, founded in 2016, employs 315 people and raised $266 million in outside funding, having most recently completed a $100 million Series E round in March 2024 co-led by Mitsubishi and Schneider Electric. As a result, Mitsubishi Electric already owns a 7% stake in Nozomi. Nozomi’s sales climbed to $74.7 million in 2024, up 19.4% from $62.6 million in 2023. The deal is set to close in 2025 (see: Schneider Electric and Mitsubishi Give Nozomi Networks $100M).
CEO Edgard Capdevielle said becoming a wholly owned subsidiary under Mitsubishi Electric will enable Nozomi to scale its operations, accelerate its pace of innovation and access new global markets all while preserving culture, brand and customer relationships. Nozomi’s revenue has been growing at a CAGR of 33%, with gross margins above 70%. The deal will reinforce its commercial strength and innovation.
“By becoming part of Mitsubishi Electric, we will combine our strengths to drive the next generation of industrial security and innovation,” Capdevielle said in a statement. “Nothing will change in our day-to-day engagement with Nozomi customers and partners. They will continue to receive the same support and service, and the same cutting-edge OT and IoT cybersecurity platform they have come to trust.”
Why Mitsubishi Electric, Nozomi Are Better Together
Becoming part of Mitsubishi Electric will help Nozomi scale its innovation globally, with the firm’s platform aligning well with modern industrial needs and complementing Mitsubishi’s OT strengths. With Mitsubishi’s global infrastructure and legacy in industrial operations, Nozomi’s technology will be deployed in more environments, protecting critical assets and systems across borders, Capdevielle said.
“The OT and IoT cybersecurity landscape is ripe with opportunities for us to lead with first-to-market solutions,” Capdevielle told Information Security Media Group in March 2024. “Customers rely on us being able to have industry firsts.”
Mitsubishi Electric plans to use Nozomi’s software, AI models and cloud infrastructure to enhance digital service offerings, particularly in data collection, threat detection, predictive maintenance and autonomous control. Nozomi’s ability to monitor networks, detect intrusions and visualize operational health aligns perfectly with Mitsubishi’s mission to optimize operations through data, the company said.
“Nozomi’s extensive implementation experience and customer touchpoints in manufacturing, buildings and infrastructure accelerates global business expansion,” Mitsubishi Electric wrote in a presentation.
The complexity and volume of operational data generated in modern OT/IoT environments require intelligent systems that can automatically detect anomalies, prioritize risks and provide actionable insights, Nozomi said. The company’s tools will serve as the cybersecurity and analytics layer within Mitsubishi’s Serendie platform, helping transform operational data into actionable insights.
“By combining Mitsubishi Electric’s century of global industrial expertise with Nozomi Networks’ innovations in data science, AI/ML and industrial cybersecurity, we have a unique opportunity to create a new generation of AI-powered solutions that will strengthen cyber and operations,” Nozomi co-founder and Chief Product Officer Andrea Carcano Takeda said in a statement.
Nozomi’s headquarters will remain in San Francisco, its R&D center in Mendrisio, Switzerland, will continue its operations and its “brand, leadership, teams and operations” will be maintained. The deal continues a trend of manufacturers buying their way into security, with Rockwell Automation acquiring industrial cybersecurity vendor Verve and Honeywell purchasing OT security firm SCADAfence in 2023.
“Nozomi Networks is committed to serving all its customers and partners by maintaining its brand, leadership, teams and operations,” the company’s press release said. “There will be no disruptions to current operations, road maps or partnerships. Nozomi’s teams, offices and points of contact remain unchanged, ensuring a seamless experience for all its stakeholders.”
