Nozomi Networks, founded in 2013, develops cybersecurity solutions for operational technology (OT) and IoT environments, with a focus on critical infrastructure. The company was built on the premise that conventional IT security tools were poorly suited to industrial control systems and OT networks, and has focused exclusively on that problem since its inception.
Its core platform combines network and endpoint visibility with AI-powered threat detection and analysis, designed to support incident response in complex industrial environments. The Guardian sensor technology operates through passive network monitoring, identifying threats and anomalies across OT and IoT environments without disrupting the underlying processes - a key constraint in industrial settings. Together, these tools give operators a unified view across OT, IoT, and IT assets.
The company's deployment footprint spans more than 12,000 installations worldwide, monitoring over 115 million OT, IoT, and IT devices. Its customers operate across energy, manufacturing, transportation, healthcare, and government sectors. Nozomi Networks reports 100% customer retention across its installed base.
The technical domains the company works across include industrial protocols, industrial control systems (ICS), passive network monitoring, endpoint visibility, and AI-driven analysis - making it a focused environment for engineers and security researchers working at the intersection of industrial systems and cybersecurity.
