SEALSQ Extends Relationship with Landis+Gyr to Offer Utilities Enhanced PKI Services for AMI Network and Meter Security

Geneva, Switzerland, June 11, 2025 (GLOBE NEWSWIRE) --

SEALSQ’s advanced Public Key Infrastructure (PKI) tool, INeS, was selected by Landis+Gyr to provide 30 million digital certificates for smart meters being deployed in the Asia Pacific region starting this summer

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced that it is partnering with Landis+Gyr (SIX: LAND), a leading global smart grid and energy management technology company to provide utilities with a flexible public key infrastructure solution.

SEALSQ’s advanced Public Key Infrastructure (PKI) tool, INeS, was selected by Landis+Gyr to provide 30 million digital certificates for smart meters being deployed in the Asia Pacific region starting this summer.

The INeS PKI solution provides robust, FIPS-certified digital certificates to ensure the security and integrity of an extensive smart meter network. These certificates are essential for authenticating devices, securing communications, and protecting against cyber threats in an increasingly connected energy ecosystem. The scope of this deployment—30 million certificates—underscores SEALSQ’s ability to deliver scalable, compliant, and cost-effective security solutions for large IoT deployments.

Landis+Gyr’s global security offerings include both on-premises and hosted solutions for data encryption, network certificates and threat monitoring.

In addition to this PKI agreement, Landis+Gyr and SEALSQ have collaborated on European projects including security solutions for over one million gas meters annually in the UK. These security elements, combined with INeS-managed PKI services, ensure compliance with local regulations and provide end-to-end security for Landis+Gyr’s smart metering solutions.
