Japanese firm Mitsubishi Electric has completed its acquisition of Nozomi Networks, a specialist in OT, IoT and cyber-physical system security.

Originally announced in September, the transaction marks the start of a new phase of growth for California-based Nozomi Networks while preserving the company’s independent operations, vendor‑neutral technology roadmap and established go-to-market partnerships. As a wholly owned subsidiary, Nozomi will continue to support the OT and ICS ecosystem with the same open, multi-vendor approach for critical infrastructure operators worldwide.

The company recently surpassed $100m in annual revenue and now serves many of the world’s largest enterprises, including five of the top ten oil and gas companies, seven of the top ten pharmaceutical manufacturers, seven of the top ten utilities and four of the top ten mining operations.

In 2025 it achieved new and expanded partnerships with Schneider Electric, Hitachi Cyber, Nvidia, Dispel and Xona.

“Mitsubishi Electric acquired Nozomi Networks for the same reasons our customers trust us every day,” said Nozomi Networks CEO Edgard Capdevielle. “We have a proven track record of innovation and industry leadership and a unique vendor-agnostic approach that is a critical ingredient to our success. We will continue to advance the highest levels of quality and excellence in our platform and relationships that we always have moving forward as an independent subsidiary of Mitsubishi Electric, and we’re excited about the opportunities this brings.”

The Nozomi Networks platform delivers asset visibility, defends all attack surfaces, and helps enterprises evolve to a risk-based cyber-security management posture. Most notably, the firm has embedded AI since its inception to push the boundaries of how this technology can transform OT and IoT cyber security. It made several enhancements to its platform in 2025, including the release of its latest version of Arc for safely automating threat response in operational environments, and the Vantage IQ AI assistant (iotm2mcouncil.org/iot-library/news/iot-newsdesk/nozomi-ai-assistant-helps-iot-security-teams/) for OT and IoT security teams.

“This acquisition brings us into a new era of innovation,” said Nozomi Networks (www.nozominetworks.com) chief product officer Andrea Carcano. “It positions us to better serve our customers globally and meet the needs of an early majority market and the challenges of a rapidly evolving OT and IoT cyber-security landscape. Nozomi is solidly positioned to extend its stature as the leader in OT and IoT cyber security. There is much more ahead for us, with game changing new innovations coming in 2026.”

Nozomi’s teams, offices and points of contact remain unchanged to ensure a seamless experience for stakeholders. Mitsubishi Electric (www.mitsubishielectric.com) is based in Tokyo and recorded a revenue of ¥5522bn for the year to March 2025.
