About
Nozomi Networks delivers comprehensive cybersecurity for operational technology (OT), IoT, and IT environments — from individual endpoints to enterprise-wide cloud management. The platform combines continuous network monitoring with AI-powered analysis to give security teams real-time asset intelligence, vulnerability management, and actionable threat detection without the noise of false positives. The platform centers on several core products: Vantage (cloud-based central management), Guardian (network sensors for wired environments), Guardian Air (wireless monitoring), and Arc (endpoint agents including embedded variants). Vantage IQ adds an AI intelligence layer for deeper insights, while integrations with Threat Intelligence and Mandiant-powered data packs keep defenses current against evolving threats. Nozomi Networks is purpose-built for industries where downtime is not an option — including electric utilities, oil and gas, manufacturing, healthcare, transportation, maritime, water treatment, and government. It supports major compliance frameworks including ISA/IEC 62443, NERC CIP, NIS2, and TSA Security Directives. With over 102 million OT, IoT, and IT devices monitored globally, a 100% customer retention rate, and recognition as a Leader in the 2026 Gartner Magic Quadrant for CPS Protection Platforms, Nozomi Networks is the trusted choice for organizations seeking resilient, scalable, and intelligent industrial cybersecurity.
Key Features
- Real-Time Asset Intelligence: Automatically discovers and profiles every OT, IoT, and IT asset on your network — including normal behavior baselines — forming the foundation for risk management.
- AI-Powered Threat Detection: Vantage IQ uses machine learning to detect security threats and process anomalies, dramatically reducing alert fatigue by surfacing only what matters.
- Continuous Network Monitoring: Guardian and Guardian Air sensors provide 24/7 passive monitoring across wired and wireless industrial networks without disrupting live operations.
- Endpoint Visibility with Arc: Arc endpoint agents — including embedded variants — extend visibility and threat detection capabilities directly to devices, from the endpoint to the cloud.
- Compliance & Vulnerability Management: Built-in support for ISA/IEC 62443, NERC CIP, NIS2, and TSA Security Directives helps organizations identify vulnerabilities and maintain regulatory compliance.
Use Cases
- Securing industrial control systems (ICS/SCADA) in manufacturing plants against ransomware and lateral movement attacks.
- Protecting electric utility infrastructure to meet NERC CIP compliance requirements and detect grid-level cyber threats in real time.
- Monitoring and securing IoT devices across smart city deployments, building automation systems, and stadiums.
- Providing healthcare organizations with OT and medical device visibility to prevent cyberattacks that could disrupt patient care.
- Enabling oil and gas operators to continuously monitor offshore and onshore environments for process anomalies and security threats.
Pros
- Unmatched OT/IoT Coverage: Monitors over 102 million devices across 11,000+ installations, covering the broadest range of industrial protocols and device types in the market.
- AI-Driven Efficiency: Vantage IQ's AI analysis reduces manual investigation time by correlating and prioritizing threats, so security teams focus on what actually needs attention.
- Proven Enterprise Trust: 100% customer retention rate and back-to-back Gartner Magic Quadrant Leader recognition reflect strong reliability and customer satisfaction.
- Flexible Deployment Options: Supports cloud (Vantage), on-premises, and hybrid deployments, adapting to the diverse infrastructure needs of industrial organizations.
Cons
- Enterprise Pricing Only: No free tier or self-serve pricing is available; the platform is designed for enterprise procurement cycles, making it inaccessible for smaller organizations.
- Complex Initial Deployment: Large or heterogeneous OT environments may require professional services engagement to achieve full deployment and integration, adding time and cost.
- Specialized Use Case: The platform is purpose-built for industrial and critical infrastructure environments; it is not suited for general IT-only cybersecurity needs.
