Mitsubishi Electric’s acquisition of Nozomi Networks is designed to strengthen its Serendie-related business, which includes OT security. Serendie is a digital platform designed to foster serendipitous data, human and technology encounters. Its name is coined from the combination of serendipity and digital engineering.
“We’ll be implementing Nozomi’s business assets, such as SaaS products, cloud-service platform and AI technology to strengthen Serendie business quality,” says Satoshi Takeda, Mitsubishi Electric senior vice president, CDO, chief information officer and board member. “We will place Nozomi’s OT security technology into our components, as well. An example is in the sequencer, equipped with intrusion detection sensor, which was launched in September 2024 to enforce edge security.”
Mitsubishi Electric’s MELSEC iQ-R programmable logic controllers (PLCs), as well as the field assets these PLCs control, down to levels 1 and 0 in the Purdue Model, include Nozomi Arc Embedded, which provides real-time visibility of internal operations. The data collected by Arc Embedded enhances anomaly and threat detection.
“The biggest aim will be co-creating new services by utilizing data,” added Takeda. “Nozomi’s solution does not just strengthen security, but will enable data collection in the overall OT arena. This is an area where various components from different vendors operate in data collection. Origins or meanings of the data were often missing. There were issues at the time of analysis and utilization of data. By using Nozomi data collection technology, we’ll be able to get rich data from the site. Through our Serendie, we will fully utilize this data to create a new service, along with our customers.”

Nozomi technology is being used in 75 countries with a customer base of 1,000 companies, not just in manufacturing, but in building and infrastructure, said Takeda.
In the industrial automation area, multiple suppliers have collaborated with Nozomi. Yokogawa began offering Nozomi’s OT visibility and threat detection to its OpreX Managed Services customers in 2024, and in 2025 Nozomi announced its Arc Embedded was embedded in Schneider Electric’s SCADAPack 47xi smart remote terminal units (RTUs).
The acquisition of Nozomi Networks brings an AI-powered, cloud-first cybersecurity software business with scalability to Mitsubishi Electric.
How will the Nozomi technology in other suppliers’ components be supported, and how will the fruits of these serendipitous data encounters be shared? Stay tuned. Exciting times are ahead, as AI and cybersecurity move deeper into the manufacturing space.
