Landis+Gyr is implementing SealsQ’s IneS public key infrastructure (PKI) to add digital certificates for electric and gas metering devices during manufacturing at its North American factories.

The process is similar to previous collaborations with SealsQ for Asian and European projects, including recently announced PKI deployments to secure 30 million utility meters for Tepco in Japan (iotm2mcouncil.org/iot-library/news/smart-energy-news/landisgyr-fan-1-1-targets-tepco-in-japan/), and strengthens an established partnership where SealsQ provides VaultIC secure microcontrollers to over one million gas meters annually in the UK.

These ensure compliance with cyber-security requirements, while streamlining Swiss firm Landis+Gyr’s end-to-end security for grid edge devices.

As edge sensors and meters begin interacting with more edge devices, such as inverters and EV chargers, security must keep pace with threat risks. Landis+Gyr’s intelligent grid edge devices provide various secure communication network options, each using end-to-end data encryption at every point of interaction with networks and devices.

SealsQ’s IneS PKI is designed for agility, supporting offline, distributed and as-a-service models to meet diverse operational needs. In offline environments, it enables secure provisioning and credential management for IoT devices and critical infrastructure without constant connectivity. For distributed use cases, it scales horizontally with decentralised certificate issuance and lifecycle management, suitable for global smart ecosystems.

As a cloud-native service, it offers scalability, automation and API-driven integration, reducing overhead while aligning with evolving regulatory demands. This tri-model flexibility ensures security and compliance across varied deployment scenarios.

“Landis+Gyr has a long history of prioritising cyber security for the grid,” said Todd Wiedman, chief security officer at Landis+Gyr. “By expanding our relationship with SealsQ at our North American manufacturing facilities, we are positioned to continue evolving our security strategy to meet the needs of our utility customers well into the future.”

Gweltas Radenac, IoT business line director for SealsQ, added: “We are delighted to reinforce our partnership with Landis+Gyr with this new agreement for North America and are committed and well prepared to help them meet the most stringent cyber-security standards on every market they address. Looking ahead, SealsQ is also pioneering the digital security industry with its next-generation quantum-resistant chips and PKI services, and we are confident our post-quantum roadmap will be a strong asset in supporting long-term industry leaders like Landis+Gyr to navigate the future post-quantum transition.”

Landis+Gyr (www.landisgyr.com) is a provider of integrated energy management. With sales of $1.7bn in 2024, it employs around 6300 people across five continents.

Swiss company SealsQ (www.sealsq.com) is an innovator in post-quantum technology hardware and software. Its technology seamlessly integrates semiconductors, PKI and provisioning services, with an emphasis on developing quantum resistant cryptography and semiconductors to address the security problems posed by quantum computing.
