Converged CPS — Head-to-Head

Claroty vs. Armis

Claroty and Armis both position as cyber-physical systems platforms covering OT, IoT, and healthcare. The surface-level similarity masks a fundamental difference in origin and depth. Claroty started in OT and expanded outward — its protocol coverage, passive deployment fidelity, and compliance evidence for industrial environments reflects that lineage. Armis started in IT asset intelligence and agentless device visibility, then extended into OT and healthcare. That difference in origin shows up most clearly in OT protocol depth and compliance posture. Organizations evaluating both should ask which direction their environment is converging from.

Criteria Claroty Armis
Platform
Primary orientation Converged CPS visibility — OT-origin platform expanded to IoT and healthcare Agentless asset intelligence — IT-origin platform expanded to OT and healthcare
Platform scope OT, IoT, healthcare (CPS) IT, OT, IoT, healthcare (full enterprise asset intelligence)
Market fit Mid-market and enterprise Enterprise — strongest in large, mixed IT/OT/IoT environments
Deployment model On-premises (CTD) or cloud SaaS (xDome) Agentless, cloud-based; passive traffic analysis and device fingerprinting
Technical
Passive deployment Yes — passive monitoring; active queries available but not required Yes — agentless and passive; no agents or active scanning required
OT protocol depth Deep — Modbus, EtherNet/IP, DNP3, IEC 61850, IEC 60870, Profinet, OPC-UA, BACnet, HART. OT-first coverage. Broad — covers OT protocols but depth reflects IT-origin platform. Less granular OT protocol decode than Claroty.
IT asset coverage IT visibility available but OT is the primary focus Full IT asset intelligence — the strongest IT device coverage of any platform in this comparison set
IoT coverage Strong IoT device visibility via xDome Strong IoT device visibility — core competency
Healthcare devices Full healthcare device management via xDome Strong healthcare device visibility — purpose-built for clinical environments
Vulnerability management Broad across CPS device types Broad across IT, OT, IoT, and healthcare
Threat detection
OT threat detection Strong — OT-specific threat detection with industrial protocol context Present — broader IT/OT/IoT scope; less OT-specific detection depth
Threat intelligence Integrated; OT and CPS focused Integrated; broader IT/OT/IoT/healthcare scope
Managed services Available through partners Available through partners
Integration and compliance
SIEM / SOAR integration Strong — one of the broader OT-focused integration libraries in the category Strong — broad integration library with IT security ecosystem emphasis
OT compliance evidence Strong — NERC CIP, IEC 62443, NIS2. OT compliance posture reflects platform origin. Compliance coverage present; less depth on OT-specific frameworks like NERC CIP
Compliance coverage NERC CIP, IEC 62443, NIS2 IEC 62443, NIS2; NERC CIP coverage less mature
Procurement
Professional services Required for deployment Required for deployment
Pricing $$$ — quote only $$$ — quote only
Watch CTD/xDome product consolidation ongoing — confirm roadmap before committing

Protocol coverage sourced from vendor documentation. Verify current capabilities during vendor briefing.

Claroty wins when

  • OT protocol depth and passive deployment fidelity in industrial environments are primary requirements
  • NERC CIP compliance evidence quality is a procurement criterion
  • Your environment is OT-primary with IoT and healthcare as secondary scope
  • You need mid-market pricing — Claroty serves below the Armis enterprise floor
  • Your SIEM integration requirements are centered on OT-contextualized alert forwarding

Armis wins when

  • Your environment is genuinely converged — IT, OT, IoT, and healthcare at comparable scale — and you need a single platform across all four
  • IT asset intelligence and device visibility are as important as OT coverage
  • Your security team sits in IT and the platform needs to fit into an IT-centric security operations model
  • Healthcare device visibility in clinical environments is a primary requirement, not secondary scope
  • You are already invested in the broader Armis enterprise asset intelligence platform

The real decision

The origin question drives the outcome here. Claroty is an OT platform that expanded to cover the full CPS stack. Armis is an enterprise asset intelligence platform that expanded to cover OT. If your primary environment is industrial — energy, manufacturing, utilities, water — and OT protocol depth, passive deployment fidelity, and NERC CIP compliance posture are your requirements, Claroty is the stronger fit.

If your environment is genuinely converged across IT, OT, IoT, and healthcare at comparable scale — a large health system with clinical devices, building automation, and corporate IT all in scope — Armis's breadth and IT-ecosystem integration depth may be the better choice. The narrowest decision point: if NERC CIP compliance evidence quality is a procurement requirement, verify Armis's current posture before shortlisting.
