Rhebo Industrial Protector
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.
