Nozomi Networks NOZOMI ARC™ vs Threats & Alerts Module: Side-by-Side Comparison (2026)

Short answer

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 security operations teams managing hybrid OT/IT environments should evaluate Threats & Alerts Module for its context-driven alert prioritization, which ranks threats by asset criticality and business impact rather than just severity scores. The platform aggregates signals across network, endpoint, remote access, and operational technology in one dashboard, cutting through alert fatigue that typically buries critical OT risks. Skip this if your organization runs purely IT infrastructure or lacks the operational technology dependencies that make Steryon's dual-domain visibility valuable.
