Mitsubishi Electric to Acquire Nozomi Networks – Security MEA
Mitsubishi Electric Corporation has signed a definitive agreement to acquire Nozomi Networks, a move that will place the industrial cybersecurity specialist as a wholly owned subsidiary while continuing to operate independently. The deal is positioned to fast-track innovation in operational technology (OT) and Internet of Things (IoT) security, with Nozomi retaining its vendor-agnostic approach for customers and partners.
The two companies aren’t strangers. Mitsubishi Electric participated in Nozomi’s $100 million Series E round announced in March 2024, and the partners have already been jointly advancing product development and go-to-market initiatives. That groundwork laid the path for this acquisition, which both sides frame as a way to scale proven technology and strengthen global delivery.
Why Mitsubishi Electric is Buying Nozomi Networks
- An AI-first OT/IoT security platform: Nozomi brings an established, cloud-focused cybersecurity stack built for industrial environments, recognized for its scalability and speed of iteration.
- Deep bench strength: Nozomi’s leadership and engineering teams have a track record of delivering market-shaping features while building a healthy, growing business.
- Global industrial reach: Backed by Mitsubishi Electric’s century of OT expertise, the combined group aims to elevate cyber resilience for critical infrastructure and industrial customers worldwide.
Mitsubishi Electric views the acquisition as a way to pair the contextual insights of OT/IoT data with advanced AI to better detect, respond to, and prevent threats—while improving operational outcomes. Both organizations emphasize a partner-first business model, customer success as a core metric, and a people-centric culture.
No Changes for Customers—And a Bigger Innovation Engine
Nozomi Networks will keep its brand, leadership, teams, and day-to-day operations intact. Existing product roadmaps, support channels, and partner programs remain in place. Offices and points of contact are unchanged, ensuring that current deployments and projects proceed without interruption.
Executives from both companies describe the deal as an accelerant rather than a reset. Mitsubishi Electric underscores the fit between Nozomi’s rapid development philosophy and its own OT capabilities, pointing to new co-created services that can lift security, efficiency, and resilience for industrial operators. Nozomi’s leadership echoes that message, noting that the combined reach and resources will supercharge product innovation while preserving the customer experience that users rely on.
Shared Vision: Data, Context, and AI at Industrial Scale
Modern industrial defense depends on understanding process behavior and context. Nozomi’s platform ingests and correlates telemetry across OT and IoT assets, then applies data science and AI/ML to identify anomalies and risks. With Mitsubishi Electric’s global footprint and domain expertise, that approach can be deployed more broadly and adapted to diverse use cases across energy, manufacturing, transportation, utilities, and other critical sectors.
The companies are aligned on accelerating digital transformation for industrial organizations. That means not only sharpening threat detection and response, but also surfacing insights that improve uptime, safety, and performance—areas where security and operations increasingly converge.
Timeline and Footprint
- Expected close: fourth calendar quarter of 2025.
- Post-close structure: Nozomi Networks will operate as an independent, wholly owned subsidiary.
- Headquarters: San Francisco, California.
- R&D hub: Mendrisio, Switzerland.
What It Means for the Market
The deal reflects a broader consolidation trend in industrial cybersecurity, where deep OT expertise and scalable AI-driven platforms are becoming table stakes. For customers, the near-term impact should be continuity: same teams, same roadmaps, same points of contact. Longer term, expect faster feature velocity, tighter integration with industrial systems, and expanded service offerings—especially for organizations looking to align security initiatives with their digital transformation agendas.
In short, Mitsubishi Electric gains a proven OT/IoT security engine, while Nozomi Networks gains the global scale to push its AI-powered capabilities into more plants, substations, and facilities. If executed as promised, the acquisition could set a new pace for industrial cyber resilience without forcing customers to rethink how they already work with Nozomi’s platform and partners.
