Rhebo Industrial Protector
Leipzig, Germany
What it is
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. Its passive design connects through mirror ports or network taps without changing industrial infrastructure, helping avoid disruption to processes. Real-time cyber-event reporting includes detailed records in PCAP format. 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. Deployment is available on premises or off premises, 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 among recognized protocols. Rhebo, founded in 2014 and headquartered in Leipzig, Germany, says it supports the industrial cybersecurity lifecycle.
