WISeKey Secures WebTrust Seal for OISTE/WISeKey Global Root of Trust, Boosting Cybersecurity Credentials.

WISeKey International Holding Ltd (WKEY) has renewed its WebTrust Seal of Assurance, reinforcing its cybersecurity credentials. The renewal covers compliance with stringent WebTrust standards, including new domains like S/MIME and Network Security. WISeKey focuses on expanding quantum-resistant trust services through its subsidiary SEALSQ Corp (LAES).

WISeKey International Holding Ltd (WKEY) has successfully renewed its WebTrust Seal of Assurance, further cementing its position as a trusted provider of cybersecurity and IoT solutions. The renewal, announced on July 29, 2025, confirms that WISeKey’s OISTE/WISeKey Trust Model and Certification Authority (CA) services meet the rigorous audit criteria established by the WebTrust program [1].

The WebTrust for Certification Authorities program, now overseen by CPA Canada, is designed to strengthen public trust in digital certificate services and the broader PKI ecosystem. By maintaining this prestigious certification, WISeKey reinforces its commitment to high security and compliance standards for its global clients [1].

The renewal covers a comprehensive audit scope, including:

- WebTrust for Certification Authorities: Validates WISeKey’s operational integrity in the issuance and lifecycle management of digital certificates.
- WebTrust for Baseline Requirements: Confirms compliance with the CA/B Forum’s security and issuance standards for publicly trusted certificates.
- WebTrust for Extended Validation (EV): Verifies WISeKey’s adherence to strict requirements for issuing EV SSL certificates.
- WebTrust for S/MIME: Introduced in 2024, it confirms WISeKey’s secure practices in issuing digital certificates for encrypted email communications.
- WebTrust for Network Security: Newly added in 2025, it attests to WISeKey’s robust cybersecurity controls across its infrastructure [1].

WISeKey delivers its trust services via next-generation certificate management platforms, offering automated provisioning (via ACME and APIs), crypto-agility, and streamlined renewal and revocation processes, reducing operational risks and improving efficiency [1].

The renewal also covers WISeKey’s newly deployed Root Certification Authorities, which serve as the foundation for its post-quantum trust services. Through its subsidiary, SEALSQ Corp (LAES), WISeKey is investing heavily in quantum-resistant solutions that integrate both software and hardware components [1].

Carlos Moreira, Founder and CEO of WISeKey, stated: “The renewal of our WebTrust assurance demonstrates the reliability and resilience of WISeKey’s Trust Services. It reflects our commitment to maintaining the highest standards of security and compliance for our global clients” [1].

In addition to WebTrust accreditation, WISeKey undergoes regular assessments to meet the diverse compliance requirements of its multinational clientele, including accreditations for Matter, Wi-SUN Alliance, and GSMA [1].

WISeKey SA, another subsidiary specializing in Root of Trust (RoT) and PKI solutions, acts as a “Trust Center” for the rest of the group, centralizing and optimizing investments in datacenter and PKI technologies [1].
