Geneva, Switzerland – June 9, 2023: WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity company, announced today that it will start providing its Security Services to GSMA members, as a GSMA Root Certificate Issuer (GSMA Root CI) in the context of eSIM Technology. WISeKey’s Root Certificate Authority (CA) has been approved by GSMA to deliver the new PKI version 3 Certificates described in SGP.22 v3.0 and SGP.14 v2.1.

SEALSQ Corp (“SEALSQ”) ( (NASDAQ: LAES), WISeKey’s subsidiary will enable companies to quickly and easily access Certificates compliant with the new version 3. The service is provided by INeS, the managed “PKI as a Service” platform without the necessity to invest and/or to deploy any hardware infrastructure.

This strong value proposition will enable not only eUICC manufacturers, but also SM-DP+/SM-DS Service Providers, to optimize time to market through cost effective and simplified design processes when requesting GSMA PKI Certificates to WISeKey’s Root Certificate Authority.

“We are pleased that WISeKey will provide its expertise to deliver eUICC manufacturers and SM-DP+/SM-DS providers across the globe with GSMA PKI certificates,” said Ian Pannell, Chief Engineer at the GSMA. “WISeKey is an expert in designing, governing and managing large PKI ecosystems to ensure eSIM certificates support millions of connected devices. We welcome the steps they’re taking to work closely with the GSMA to shape the security in the cellular space.”

“The unique combination of SEALSQ’s provisioning services with the GSMA Root-of-Trust CI will help our customers save time by issuing GSMA PKI Certificates to GSMA eSIM compliant version 3 Consumer products,” said Pedro Fuentes, Trust Services Manager of WISeKey.

The growing adoption of eSIM standards and the remote SIM provisioning will greatly improve interoperability between devices and security-by-design in the cellular industry, creating a more efficient and safer experience for consumers. This is in full alignment with SEALSQ’s mission to contribute into building a safer connected world.
