Who is Nozomi Networks?
Nozomi Networks is a cybersecurity vendor that provides Operational technology (OT), industrial control system (ICS), and Internet of Things (IoT) network visibility and threat detection platforms for critical infrastructure and industrial enterprises.
- OT and ICS network monitoring and asset visibility platforms for industrial and critical infrastructure environments (industrial cybersecurity)
- Threat detection, anomaly detection, and intrusion detection for Supervisory Control and Data Acquisition (SCADA), Distributed Control System (DCS), and other control system networks (network security)
- Security monitoring and risk management for IoT and cyber-physical systems across distributed sites (IoT security)
- Deployment options for on-premises (on-prem), data center, and cloud-connected monitoring of industrial networks (hybrid security architecture)
- Integration with Security Information and Event Management (SIEM), SOC workflows, and Security Operations (SecOps) tools for centralized incident response (security operations)

More About Nozomi Networks
Nozomi Networks focuses on cybersecurity for OT, industrial control systems (ICS), and IoT environments used in sectors such as energy, manufacturing, transportation, and other critical infrastructure domains. Its platforms monitor network traffic and assets across SCADA, DCS, and other industrial automation systems to provide visibility into devices, communications, and security posture. The company’s offerings are positioned for organizations that operate cyber-physical systems where availability, safety, and regulatory compliance are central concerns.
The Nozomi Networks portfolio centers on OT and IoT network monitoring and threat detection (industrial cybersecurity). Its technology typically uses passive network traffic inspection and deep packet analysis to build an inventory of assets, map communication patterns, and detect anomalies or potential threats. Support for industrial protocols such as Modbus, DNP3, Indirect Evaporative Cooling (IEC) 60870-5-104, OPC, and others is a core technical element, allowing inspection of control system traffic that is not addressed by conventional IT security tools. These capabilities are designed to coexist with PLCs, RTUs, HMIs, and other ICS components without interfering with their operation.
From an architectural perspective, Nozomi Networks solutions are deployed as sensors across OT and IoT networks, feeding data into centralized management and analytics components (network security, security analytics). This architecture supports segmentation between OT and IT domains while still enabling centralized visibility. The platforms integrate with SIEM systems, ticketing tools, and SecOps center (SOC) workflows, so OT security alerts can be correlated with broader enterprise security events.
Nozomi Networks is typically categorized in directories under OT security, ICS security, industrial cybersecurity, and IoT security. Its tools provide asset discovery, vulnerability context, threat and anomaly detection, and incident forensics for industrial environments. Compared with traditional IT-focused network security solutions, Nozomi Networks emphasizes support for industrial protocols, legacy systems, and deterministic control traffic patterns. This orientation aligns its products with infrastructure protection and safety objectives as well as cybersecurity risk management.
Enterprises and institutions use Nozomi Networks to gain a structured view of their OT and IoT environments, assess exposure, and operationalize monitoring of industrial networks. The platforms can support use cases such as compliance reporting, baseline behavior analysis for critical processes, and early detection of malware or misconfigurations that affect control systems. In multi-vendor environments, Nozomi Networks operates alongside firewalls, endpoint protection, and other security tools, contributing OT-specific context to enterprise security architectures.
