Rhebo IIoT Security is an industrial network monitoring with anomaly detection and security automation for manufacturers and operators of critical (I)IoT devices. The security monitoring agent is specially tailored to the CPU and memory constraints of IoT devices to allow local integration and operation. Both installation and updates can be executed remotely. This also enables the fast and easy upgrade of existing systems. Within a few hours Rhebo IIoT Security learns the authorized and expected communication of the devices. During operation, all communication is monitored both on and between the IoT devices and the cloud-based IoT platform. Deep packet inspection technology ensures a thorough analysis down to value level. Any deviation from the authorized pattern is reported as an anomaly while security automation stops any event locally to ensure fleet protection. Rhebo fully supports companies from the energy sector along the industrial cybersecurity lifecycle from the initial risk analysis to managed IIoT monitoring with threat & intrusion detection.
