OT Visibility — Head-to-Head

Nozomi Networks vs. Claroty

Nozomi and Claroty overlap significantly on paper — both cover OT and IoT visibility, both deploy passively, both serve enterprise environments. The difference is in architecture and emphasis. Nozomi is built for large, distributed, multi-site operations where AI-driven analytics and scale matter most, with wireless spectrum monitoring as a genuine differentiator. Claroty is built around converged CPS visibility — OT, IoT, and healthcare — with stronger SIEM integrations and a cloud SaaS path that Nozomi's architecture does not match. For most single-site or moderately complex environments, the choice comes down to which integration ecosystem fits your SOC and whether healthcare device visibility is in scope.

Criteria Nozomi Networks Claroty
Platform
Primary orientation AI-driven OT and IoT asset intelligence and anomaly detection at scale Converged CPS visibility across OT, IoT, and healthcare
Platform scope OT and IoT; no healthcare device coverage OT, IoT, healthcare (CPS)
Market fit Enterprise — strongest in large, multi-site industrial operations Mid-market and enterprise
Deployment model Guardian sensors aggregate to cloud-based Vantage platform On-premises (CTD) or cloud SaaS (xDome)
Technical
Passive deployment Yes — passive-only monitoring Yes — passive monitoring; active queries available but not required
Protocol coverage Modbus, EtherNet/IP, DNP3, IEC 61850, IEC 60870, Profinet, OPC-UA, BACnet, GOOSE, Wireless Modbus, EtherNet/IP, DNP3, IEC 61850, IEC 60870, Profinet, OPC-UA, BACnet, HART
Wireless monitoring Yes — wireless spectrum monitoring included. Detects rogue wireless devices and unauthorized RF activity. No native wireless spectrum monitoring
AI / analytics AI-driven anomaly detection and asset intelligence. Strongest analytics depth in the category. AI-assisted; less analytics emphasis than Nozomi
Asset discovery Strong — AI-driven asset intelligence across OT and IoT Strong — broadest device type coverage including healthcare
Vulnerability management Strong — contextualized for OT and IoT asset risk Broad across CPS device types
Multi-site scale Designed for large, distributed environments. Guardian sensor architecture aggregates cleanly at scale. Scales well but architecture optimized for converged CPS breadth, not distributed OT depth
Threat detection
Threat intelligence Integrated threat intelligence; strong OT and IoT coverage Integrated; broader IT/OT/IoT/healthcare scope
Response playbooks Available; general OT focus Available; broader CPS focus
Managed services Available through partners Available through partners; not a native offering
Integration and compliance
SIEM / SOAR integration Supported; solid OT-contextualized integration Strong — one of the broader integration libraries in the category
Healthcare device visibility Not in scope Full healthcare device management via xDome — a genuine differentiator for converged environments
Compliance coverage NERC CIP, IEC 62443, NIS2 NERC CIP, IEC 62443, NIS2
Procurement
Professional services Required for deployment Required for deployment
Pricing $$$ — quote only $$$ — quote only

Nozomi wins when

  • You are operating a large, multi-site industrial environment — utilities, distributed energy, transportation — and need consistent OT and IoT visibility at scale
  • Wireless spectrum monitoring is a requirement — rogue wireless devices and unauthorized RF are a threat in your environment
  • AI-driven analytics and anomaly detection depth matter more than platform breadth
  • Your deployment is primarily OT and IoT with no healthcare device scope
  • Your architecture is sensor-to-cloud and you are comfortable with the Vantage aggregation model

Claroty wins when

  • Your environment includes healthcare devices alongside OT and IoT — you need a single platform for the full CPS scope
  • You want cloud-based SaaS deployment flexibility via xDome
  • Your SIEM and SOAR integration requirements are extensive and you want the broadest connector library in the category
  • You need mid-market pricing and large-scale enterprise platforms are out of reach
  • Your organization spans manufacturing, healthcare, and OT — CPS convergence is the primary requirement

The real decision

For large, distributed OT and IoT environments — utilities, multi-site manufacturing, distributed energy — where scale, wireless monitoring, and AI-driven analytics are the priority, Nozomi is the stronger fit. For converged environments that include healthcare devices, or where a broad SIEM integration library and SaaS deployment flexibility matter, Claroty is the better choice.

The narrowest decision point: if wireless spectrum monitoring is a requirement, Nozomi is the only platform in this pairing that provides it. If healthcare device visibility is a requirement, Claroty is the only option. Neither platform publishes pricing.
