Nozomi Networks NOZOMI ARC™ vs VicOne xCarbon: Side-by-Side Comparison (2026)

Nozomi Networks NOZOMI ARC™

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.

VicOne xCarbon

Enterprise automotive OEMs and tier-one suppliers will get real value from VicOne xCarbon because it detects in-vehicle attacks at the ECU level with minimal computational overhead, something generic network security tools simply cannot do. The 2,000+ automotive-specific threat rules and edge AI correlation across ECUs mean you catch CAN bus anomalies and malicious messages before they reach safety systems, addressing the detection gap most teams face when bolting IT security onto vehicle networks. Skip this if your organization runs only a handful of vehicles or treats automotive cybersecurity as an afterthought; xCarbon requires integration into your firmware deployment pipeline and assumes you're serious about continuous monitoring at the edge.
