Rhebo

What Rhebo does

Rhebo GmbH is a Leipzig-based cybersecurity vendor founded in 2014 that provides passive network-based intrusion detection and anomaly monitoring for industrial control systems and critical infrastructure operators. Its platform centers on two products — Rhebo OT Security for operational technology networks and Rhebo IIoT Security for edge devices and Industrial IoT assets — supplemented by an Industrial Security Assessment service and the Rhebo Industrial Protector module for building automation. The core technology passively analyzes OT/ICS network traffic to build per-environment behavioral baselines and flag cyberattacks, vulnerabilities, malware, and operational error states in real time, with integration paths into enterprise SIEM platforms and alignment with the MITRE ATT&CK for ICS framework.

Rhebo serves primarily energy utilities, transmission and distribution system operators, water/wastewater utilities, waste-to-energy operators, and discrete manufacturing companies, with additional exposure to hospitals, renewable energy plants, oil & gas, and data center building automation. Visible customers include Stadtwerke Bochum, Thüringer Energienetze, Stromnetz Hamburg, EnBW, Mitnetz Strom, envia TEL, Leipziger Wasserwerke, Rexroth (Bosch), Fraunhofer, sonnen, and BayWa r.e. — a German-centric, enterprise-heavy customer set.

The business operates a B2B enterprise field sales motion with quote-based annual subscriptions for software, complemented by professional services (risk assessments, implementation) and managed detection services that bridge the OT security skills gap. Distribution is direct plus a network of sales consulting partners across the DACH region, supported by channel partnerships with BBH Group and standards-body memberships (ECSO, bitkom, Allianz für Cyber-Sicherheit). The company is in the process of transitioning ownership from Landis+Gyr Group AG (which acquired it in 2021) to Everfield Germany GmbH under a definitive agreement signed in April 2026 at a high single-digit million USD enterprise value, with Everfield explicitly positioned as a buy-and-hold investor to accelerate EMEA expansion.

Core offering

Rhebo provides OT (Operational Technology) security software and managed services for industrial control systems and critical infrastructure. Its core offerings include Rhebo OT Security (passive network intrusion detection and anomaly detection for SCADA/ICS networks) and Rhebo IIoT Security (cybersecurity for IIoT edge devices), complemented by vulnerability assessments and managed detection services that bridge the OT security skills gap.

Product overview

Rhebo provides a unified OT cybersecurity platform consisting of two core products: Rhebo OT Security (for Operational Technology networks) and Rhebo IIoT Security (for Industrial IoT edge devices). These products work together to provide comprehensive coverage from central control rooms to IIoT edge devices. Key solution pillars include: (1) Risk and vulnerability assessment, (2) Network intrusion detection system (NIDS) with continuous OT security monitoring and anomaly detection, and (3) Managed security services. The platform is complemented by specialized offerings such as Rhebo Industrial Protector for attack detection and Rhebo Industrial Security Assessment for vulnerability analysis. The company emphasizes 'Made in Germany' cybersecurity for energy sector, critical infrastructure, and manufacturing companies, supporting the full OT security lifecycle from initial risk analysis to managed OT monitoring with anomaly and attack detection.
