Landis+Gyr Group AG announced on April 30, 2026, that it has signed a definitive agreement to sell Rhebo GmbH to Everfield Germany GmbH, a buy-and-hold investor in European B2B SaaS businesses. The divestiture transfers a specialized operational technology (OT) cybersecurity capability to a dedicated industrial software investor, marking a new phase of consolidation in European industrial threat monitoring. Completion of the transaction remains subject to customary regulatory approvals and standard closing conditions.
Background
Founded in 2014 and headquartered in Leipzig, Germany, Rhebo provides security monitoring and anomaly detection for industrial OT networks and IIoT environments, enabling operators to identify cyber threats without disrupting ongoing operations. Rhebo has been part of Landis+Gyr Group since 2021.
Built specifically for OT systems, Rhebo's technology integrates into existing infrastructures and supports compliance with evolving regulations such as NIS2 and the Cyber Resilience Act. Rhebo holds ISO 27001 certification and the "Cybersecurity Made in Europe" label. These credentials carry growing weight as EU member states intensify enforcement of cross-sector security obligations across critical infrastructure and manufacturing supply chains.
Everfield, a buy-and-hold investor in European B2B SaaS businesses, operates a decentralized model that allows acquired companies to retain their brand and operational independence while accessing shared expertise. The acquisition expands Everfield's European ecosystem, which now includes more than 40 B2B software companies across Europe and 10 in the DACH region.
Details
Landis+Gyr is selling Rhebo as part of a strategic realignment to focus on its core business. The transaction is valued at an enterprise value in the high single-digit million US dollar range, subject to regulatory approvals.
Todd Wiedman, who served as CEO of Rhebo from 2023 to 2026 and is CISO of Landis+Gyr, attributed the move to portfolio focus: "As part of sharpening our strategic focus on our core business, Landis+Gyr decided to carve out our Rhebo OT security product division and transfer it to a strong European investor," Wiedman stated. He added that Everfield's "dedicated resources, deep expertise, and clear commitment to the EMEA market" position the OT security business to accelerate growth.
Oscar Koberling, Country Manager for DACH at Everfield, cited the strategic value of the deal: "With a strong market position in DACH and deep technical expertise in OT security, Rhebo adds a critical capability to our ecosystem," Koberling said.
With Rhebo joining the group, Everfield adds dedicated OT security expertise to its Business and Industrial Systems vertical, complementing existing OT software capabilities including ondeso, a Regensburg-based OT management software provider.
Gerald Müller, CEO of Rhebo since 2026, framed the transaction in terms of European industrial sovereignty: "The investment focus on European B2B software companies is also a clear commitment and a strong opportunity for us to advance European digital sovereignty," Müller said.
Everfield has confirmed that Rhebo's management team will remain in place and that the company's headquarters and development operations will stay in Leipzig.
Outlook
Everfield plans to leverage its long-term SaaS expertise to grow Rhebo's OT cybersecurity business across the EMEA region. For manufacturers in Germany, Austria, and Switzerland, the consolidation places a dedicated OT threat detection capability within an ecosystem already oriented around industrial process software - a configuration that could accelerate joint incident response and cross-portfolio data sharing as NIS2 compliance deadlines approach. Regulations such as NIS2 and the Cyber Resilience Act are increasing pressure on operators to strengthen resilience across connected infrastructure, making the deal's timing significant for the broader DACH manufacturing sector.
