Rhebo Industrial Protector is a network-based intrusion detection system for operational technology networks. It continuously observes OT communications and applies anomaly detection to identify cyberattacks, tampering, and technical failures. The passive approach is designed to avoid disrupting industrial processes, and deployment can use mirror ports or network taps without modifying OT infrastructure. Real-time event reporting includes detailed PCAP documentation. The system visualizes active devices, firmware status, protocols, connections, and known vulnerabilities to support asset management and OT documentation. Standard-based SIEM integration brings OT security information 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 among recognized protocols. Rhebo identifies critical infrastructure, utilities, and manufacturing as intended users, and describes support from risk analysis through managed monitoring.
