Claroty xDome vs Rhebo Industrial Protector

Claroty xDome gives security teams visibility into cyber-physical systems and context for assessing risk. It discovers assets through multiple methods, including non-passive techniques that can find devices before a passive collection server is deployed. Discovery updates the inventory, and the CPS Library helps identify devices. Teams can prioritize exposures by production line, system, and business purpose, with AI-powered remediation recommendations. xDome maps device communications and recommends micro-segmentation policies; device clustering can support zones aligned with IEC 62443. It also identifies known and emerging CPS-specific threat indicators and relates alerts to business context. Claroty says its platform covers more than 450 protocols; Modbus is listed as supported. Integration options include SIEM, SOAR, CMDB, maintenance, vulnerability, ticketing, network access, and endpoint tools, plus an MCP Server for AI ecosystems. It is a cloud-native modular SaaS platform available through web and API. Pricing is on request.

Rhebo Industrial Protector is a network-based intrusion detection system for operational technology networks. It continuously monitors OT communications and uses anomaly detection to identify cyberattacks, tampering, and technical failures. Its passive design connects through mirror ports or network taps without modifying OT infrastructure, aiming to avoid disruption to industrial processes. Real-time cyber-event reporting includes detailed PCAP records. The system visualizes active devices, firmware status, protocols, connections, and known vulnerabilities for OT documentation and asset management. Standard-based SIEM integration can bring OT security events into enterprise cybersecurity systems. Rhebo offers on-premises and off-premises deployment, including physical and virtualized on-premises appliances; VMware ESXi is listed for virtual deployments. Specifications state that all OT communication protocols are detected and logged, with OPC, IEC 60870-5-104, IEC 61850-8-1, and DNP3 listed. Rhebo identifies critical infrastructure, utilities, and manufacturing as intended users.
