Management and security of energy supply from a single source. Landis+Gyr and Rhebo combine top performance, innovative strength and unbeatable wealth of experience from two worlds of the energy industry.

As a leading global provider of integrated energy management solutions for energy supply companies, Landis+Gyr help their customers to master their complex challenges in the areas of smart metering, grid edge intelligence and smart infrastructure.

The growing threat to critical infrastructures, and in particular to the increasingly digitized energy grids, brought Rhebo to the attention of Landis+Gyr's 2020 management.

Rhebo's OT security solutions, ranging from central OT to the IIoT edge, and strong focus on the energy industry's OT networks made Rhebo the perfect match for Landis+Gyr.

Since February 2021, Rhebo has been an integral part of the Landis+Gyr family and joined the product portfolio as its cybersecurity branch.

Landis+Gyr and Rhebo

The best of two worlds

Landis+Gyr and Rhebo combine top performance, innovative power and unmatched expertise thus bringing together two interdependent worlds of energy supply: efficient management and uncompromising security.

‍Landis+Gyr has been developing and delivering pioneering energy supply management solutions for over 115 years. In 1896, the company started with the production of power meters. Today, with 7,500 employees in 30 countries on all five continents, it offers fully integrated energy management solutions for the smart grid era.

In 2015, Rhebo innovated the cybersecurity of industrial networks with the development of a network-based intrusion detection system for OT. With its passive OT monitoring with anomaly detection, Rhebo has since enabled utility, water and industrial companies to effectively protect their historically "insecure by design" industrial processes against cyberattacks and error conditions.

Since 2021, Landis+Gyr and Rhebo have combined smart energy management with powerful cybersecurity sharing a common goal for their customers: To manage energy better.
