Nozomi Networks provides passive and active network sensors, plus a cloud SaaS layer (Vantage), that monitor OT and IoT networks for anomalies, misconfigurations and threats in industrial environments such as utilities, manufacturing and transportation. The platform builds a live asset inventory and behavioral baseline of ICS traffic, then flags deviations that could indicate intrusion, misconfiguration or equipment failure.
Founded in 2013 and headquartered in San Francisco, Nozomi has built strategic OEM relationships with industrial equipment makers including Mitsubishi Electric and Schneider Electric, which embed Nozomi’s sensor technology into their own product lines — a distribution channel most pure-play OT security vendors lack. The company has raised roughly $266 million in total funding, including a $100 million Series E in 2021.
Nozomi is consistently ranked among the Leaders in Gartner’s Magic Quadrant for Cyber-Physical Systems Protection Platforms, placing second on Ability to Execute behind Claroty, alongside competitors Dragos and Armis.
Innovation Matrix Assessment
Long, steady track record of protocol-support and detection expansion since 2013, but no major recent product-line leap found in public reporting.
Gives OT security teams continuous visibility and anomaly detection across industrial networks that traditionally ran with little to no monitoring.
Independently verified OEM partnerships with Mitsubishi Electric and Schneider Electric and a $100M Series E, though the company's most recent public mega-round dates to 2021, making momentum evidence less current than top peers. Recognized in Cyber Defense Media Group's 2026 Global InfoSec Awards (1 award), independently juried industry validation of market traction.
A credible, well-established player in OT monitoring, but shares the category with Claroty, Dragos and Armis rather than defining it alone. However, Nozomi Networks is being acquired by Mitsubishi Electric in a deal valuing the company at approximately $1B, expected to close Q4 2025 (per cyberscoop.com), which is the scale of an established incumbent rather than an emerging category disruptor, so this dimension is scored more conservatively.
Consistently ranked a Leader in Gartner's CPS Protection Platforms Magic Quadrant, including second place on Ability to Execute, a credible independent signal.
OT/IoT monitoring remains a durable need as industrial environments connect further, though the category is maturing and competitive.
Why CISOs Should Care
Provides continuous OT/IoT network visibility and anomaly detection in environments that historically had no monitoring at all, and does so through embedded OEM relationships with major industrial vendors.
What Makes It Different
Distribution through OEM embedding in Mitsubishi Electric and Schneider Electric products, rather than relying solely on direct enterprise sales.
The Matrix Verdict
67/100 — INCREMENTAL INNOVATOR
An Incremental Innovator: Nozomi is a real, independently ranked OT security leader with valuable OEM distribution, but its funding and momentum signals are less recent and smaller than category peers Claroty and Dragos.
Editorial Note: Claims vs. Verified Findings
OEM partnership scope and platform capabilities are drawn from company and press reporting; no independent efficacy benchmark or breach-response case study was found in this research.
