Rhebo Industrial Protector

What Rhebo Industrial Protector is

Rhebo Industrial Protector is a network-based intrusion detection system for operational technology (OT) environments. It continuously monitors OT communications and uses anomaly detection to identify cyberattacks, tampering, and technical failures. Its passive approach is designed to avoid disrupting industrial processes; integration through mirror ports or network taps does not require changes to OT infrastructure. The system provides real-time cyber-event reports with detailed PCAP records and visualizes active devices, firmware status, protocols, connections, and existing vulnerabilities for asset management and OT documentation. Standard-based SIEM integration can bring OT security information into enterprise cybersecurity systems. Deployment options include on-premises and off-premises setups, with physical and virtualized on-premises appliances; VMware ESXi is listed for virtual deployments. The specification says it detects and logs all protocols in OT communications and identifies OPC, IEC 60870-5-104, IEC 61850-8-1, and DNP3 among recognized protocols. Rhebo identifies critical infrastructure, utilities, and manufacturing as intended users. It says it supports industrial cybersecurity from initial risk analysis through managed OT monitoring.
