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.

Broad incumbents
- Darktrace: Darktrace applies AI-based anomaly detection across IT and OT environments, with industrial customers using its self-learning approach for OT monitoring — an adjacent competitor offering broader cyber coverage than Rhebo's specialized OT focus.
- Palo Alto Networks: Palo Alto Networks provides OT security capabilities through its broader cybersecurity platform (including IoT/OT security features). As a large incumbent with massive R&D and global sales reach, it competes with Rhebo for enterprise security budgets in industrial accounts.
- Cisco (Cyber Vision): Cisco offers Cyber Vision for OT visibility and security as part of its broader industrial networking portfolio. While not specialized like Rhebo, Cisco's global scale and installed industrial base create competitive pressure in the same enterprise accounts.
