Rhebo is a German company based in Leipzig that develops security monitoring for industrial control and operational technology (OT) networks. Its Industrial Protector is a network-based intrusion detection system that detects cyberattacks and technical faults in OT networks, while the lighter IIoT Protector covers distributed IIoT installations. Rhebo also offers a managed protection service for operating the detection system. The company presents itself as OT security made in Germany, a claim that reflects the vendor's own positioning.
Rhebo has been wholly owned since January 2021 by the Swiss group Landis+Gyr, headquartered in Zug. The website does not state where customer data is hosted. The product is not presented as open source. Organisations should have support arrangements, the hosting location of monitoring data and access to that data confirmed in writing, particularly given the Swiss parent group.
