PSI and Rhebo Cooperate on Cybersecurity of Critical Infrastructures

Securing PSI network control systems through operational technology monitoring

Berlin, February 28, 2023 - PSI Software AG and Rhebo GmbH, a German provider of industrial cyber security, have signed a cooperation agreement to increase the cyber security of critical infrastructures. The background to the cooperation is the IT Security Act 2.0, which comes into force on 1 May 2023. As a Trusted IDS Partner, Rhebo will exclusively secure PSI control systems in the core zone via Operational Technology (OT) Monitoring with anomaly detection.

Customers of PSI in the areas of industry and critical infrastructures, in particular energy supply, have the option of using the Rhebo Industrial Protector to secure the core zone within the PSI control system. The OT monitoring solution also monitors the entire communication. Deviations from expected patterns are detected and reported in real time. This allows cyber incidents that indicate compromise or misconduct to be detected early and shut down immediately.

"The core zone is the heart of any PSI control system. It is managed as a high-security zone within the Operational Technology of industrial companies, to which only PSI personnel have access," explains Wolfgang Fischer, PSI Business Unit Manager Electrical Energy. He adds: "With Rhebo, we are bringing an experienced partner on board who, with OT Security Made in Germany, meets our high standards of trustworthiness and quality. Of course, we accompany our customers during implementation and ensure individual and documented adjustments in PSIcontrol."

In addition, with PSIdetect, PSI offers a software product that detects abnormal behavior in the equipment properties and analyzes measured values and data from the core zone of the control system.
