Nozomi Networks NOZOMI ARC™ is a commercial industrial control system security tool by Nozomi Networks. Claroty Platform is a commercial industrial control system security tool by Claroty. Compare features, ratings, integrations, and community reviews side by side to find the best industrial control system security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market teams protecting critical manufacturing and utility infrastructure need NOZOMI ARC™ for its ability to catch USB-based attacks and malicious input devices at the host level, a gap most OT security tools leave open. The tool covers six NIST CSF 2.0 functions across asset discovery, continuous monitoring, and threat response, with three enforcement modes that let you move beyond detection when an anomaly demands immediate isolation. Skip this if your environment is mostly IT-facing or you need lateral movement detection across the network; NOZOMI ARC™ excels at endpoint-level control but assumes you have network segmentation and a Nozomi Guardian deployment already in place.
Mid-market and enterprise operations teams need Claroty Platform because it actually finds and inventories OT assets without stopping production lines, which most IT-first tools fail at. The passive network monitoring and AI-driven device library cover ID.AM and DE.CM across industrial, IoT, and healthcare environments simultaneously; active safe queries let you interrogate devices without triggering alarms. Skip this if your threat model is purely IT-side or if you need strong incident response automation; Claroty prioritizes visibility and exposure management over recovery workflows.
