Everfield acquires German OT security firm Rhebo to expand industrial cybersecurity portfolio

Everfield has agreed to acquire Rhebo, a Leipzig-based OT security monitoring and anomaly detection specialist serving critical infrastructure providers, as regulatory pressure from NIS2 and the Cyber Resilience Act intensifies.

Everfield, a buy-and-hold investor in European B2B SaaS businesses, has agreed to acquire Rhebo, a German technology company specializing in security monitoring and anomaly detection for industrial (OT) networks and IIoT environments, according to official disclosures. Founded in 2014 and headquartered in Leipzig, Rhebo provides continuous OT monitoring and anomaly detection to critical infrastructure providers and large enterprise customers.

Its solutions enable anomaly detection and cyber threat identification across OT networks and IIoT edge devices without disrupting ongoing industrial operations. This development matters because evolving regulations such as NIS2 (Network and Information Security Directive) and the EU Cyber Resilience Act are increasing pressure on industrial operators to strengthen the security and resilience of connected infrastructure.

Rhebo supports compliance by delivering continuous network monitoring and actionable insights tailored to industrial environments, where traditional IT security tools are often unsuitable. Industries impacted include industrial cybersecurity, critical infrastructure protection, manufacturing, energy, and utilities.

Regional stakeholders include European industrial operators, regulatory authorities, and OT security vendors.

For investors, the acquisition reflects consolidation in the fragmented OT security market, driven by regulatory tailwinds. Everfield’s buy-and-hold model suggests long-term commitment to Rhebo’s product roadmap rather than short-term integration, potentially preserving customer continuity and R&D focus.

Everfield is a European investment firm headquartered in Paris, focused on acquiring and operating B2B SaaS companies.

Rhebo is a German industrial cybersecurity company based in Leipzig, providing OT network monitoring and anomaly detection solutions.
