Nozomi Networks Platform

Overview

Nozomi Networks Platform is an OT and IoT security platform for organizations protecting industrial networks, commercial sites and critical infrastructure. It suits teams that need asset context and security workflows tailored to operational technology; its breadth is a strength, while the pay-as-you-grow OnePass subscription is priced by assets protected.

Founded in 2013 and headquartered in San Francisco, Nozomi can send Guardian sensor data to an on-premises Central Management Console or cloud Vantage. That choice gives organizations flexibility over where they manage security data, but it also makes deployment planning part of the buying decision.

Key features

Asset discovery and response

Continuous discovery maps wired and wireless assets, communications, vulnerabilities and behavioral anomalies. Passive monitoring and OT asset discovery are supported, with protocols including Modbus, IEC 61850-8-1 (MMS), EtherNet/IP, PROFINET and BACnet. This depth is valuable for teams that need to understand industrial traffic; the platform's emphasis is on OT and IoT rather than a general-purpose endpoint security workflow.

OT- and IoT-specific threat intelligence supports high-fidelity detections, response playbooks and prioritized remediation guidance. That pairing helps teams move from identifying a suspicious event to deciding what to address first.

Analytics and risk

Neural networks, clustering and time-series analysis correlate behavior across assets, traffic and time to support root-cause analysis. Dynamic risk scores can be weighted for vulnerabilities, alerts, communications, device characteristics, asset criticality and compensating controls. Custom weighting can help reflect operational priorities, though teams must decide which factors matter most in their environment.

AI assistant and integrations

Vantage IQ uses an LLM grounded in OT-native intelligence and can be configured for roles including SOC analyst, OT engineer and CISO. The role-based approach fits organizations with different security and operations audiences; no additional performance or outcome claims are warranted.

Integrations include AWS, Microsoft Azure, ServiceNow, Splunk, IBM QRadar, ArcSight, Active Directory, LDAP, Cisco ISE, email and SMS. OpenAPI integration and export capabilities let teams send data to other applications for analysis and reporting, a practical advantage where security information already flows through established tools.

Deployment and scale

Guardian sensors can run as hardware appliances, virtual machines, embedded devices or containers. Large-enterprise configurations support up to 500,000 nodes and maximum throughput of 3–6 Gbps, giving the platform a stated ceiling for sizable deployments. The platform provides encryption using approved algorithms such as AES and SHA-256, aligned with NIST SP 800-131a; Nozomi also performs continuous dynamic vulnerability scanning, software-composition analysis and annual third-party penetration tests. Customers can choose among multiple AWS datacenter locations for storage and processing.

Pricing

Nozomi Vantage SaaS is free. It provides cloud-hosted security infrastructure and is used to license hardware and Guardian nodes; asset and threat-intelligence subscriptions can be bundled. This is a useful no-charge entry point for licensing the infrastructure, but it is not described as a complete free security subscription.

Nozomi OnePass is a paid, pay-as-you-grow subscription with custom pricing based on the number of assets protected. It includes Nozomi hardware and software, bundled support and optional subscriptions, plus extra Guardian software nodes at no incremental cost. The asset-based model may suit organizations that want one subscription across hardware and software, but buyers should request a quote to assess cost at their scale.

Customers can access answers, resources and support cases through the Nozomi Networks portal.

Platforms

Nozomi supports API, Linux, self-hosted and web deployments. Guardian's appliance, virtual machine, embedded-device and container options give infrastructure teams several ways to place sensors, while Vantage and Central Management Console provide cloud and on-premises management paths.

Who it's for

Nozomi is a strong fit for industrial operators, commercial organizations and critical-infrastructure teams that need continuous OT asset visibility, tailored threat detection and risk-based remediation. Its protocol coverage, deployment choices and integrations also make it relevant to teams managing diverse sites and security systems. It is less compelling for buyers seeking a straightforward public-price comparison or a general-purpose security platform without an OT focus.

Pros and cons

• Pros: Continuous discovery connects asset, communication, vulnerability and anomaly context, supporting more informed OT security decisions.
• Pros: Risk scores can be customized around operational criticality and compensating controls, not just vulnerability and alert data.
• Pros: Sensor deployment options and large-enterprise scale support varied infrastructure and substantial node counts.
• Cons: OnePass uses custom asset-based pricing, so organizations cannot readily compare its subscription cost without a quote.
• Cons: Vantage SaaS is free for cloud-hosted security infrastructure and licensing, but asset and threat-intelligence subscriptions may be bundled separately.

Alternatives

Verdict

Choose Nozomi Networks Platform if your organization needs broad OT and IoT visibility, configurable risk prioritization and response guidance across complex infrastructure. Its strongest case is the combination of industrial asset context, analytics and flexible sensor deployment. Look elsewhere if upfront price transparency or a platform without a specialized OT focus matters more than that depth.
