SEALSQ Corp (NASDAQ: LAES) (“SEALSQ”), a leader in post-quantum semiconductors, PKI, and secure hardware solutions, today announced the upcoming launch of a U.S.-based Post-Quantum Root of Trust, set to go live on Friday, November 21, 2025. This sovereign infrastructure is designed to enable American enterprises and government agencies to issue, manage, and validate quantum-resistant digital identities and PKI services entirely on U.S. soil.

The new platform aims to bolsters national cybersecurity and digital sovereignty by delivering locally controlled, quantum-secure certificate issuance, lifecycle management, and hardware-anchored device provisioning for IoT, industrial control systems, telecommunications, and cloud environments.

Built as an extension of SEALSQ’s INeS platform, the U.S. Post-Quantum Root plans to support secure device onboarding, scalable credential management, and remote lifecycle operations. Starting November 21, organizations will be able to generate Post-Quantum Certificates and device identities compliant with CNSA 2.0, mitigating supply-chain vulnerabilities and preparing for forthcoming federal Post-Quantum Cryptography (“PQC”) mandates.

Fully aligned with NIST’s PQC standards and supporting hybrid classical + PQC trust models, the Root of Trust integrates seamlessly with SEALSQ’s secure semiconductor lineup, including the Quantum Shield QS7001 PQC-enabled hardware platform, to provide end-to-end protection against future quantum threats.

U.S. agencies and critical infrastructure operators are accelerating hardware trust anchors and PQC migration under NIST guidelines and NSA’s CNSA 2.0. In collaboration with WISeSat, also a WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY) company, SEALSQ plans to secure WISeSat’s growing satellite constellation, delivering a sovereign, hardware-secured, post-quantum-ready trust layer for space and terrestrial IoT networks. This partnership aims to meet U.S. demands for trusted space assets, resilient supply chains, and quantum-resistant connectivity—laying a secure foundation for next-generation digital infrastructure.

Carlos Moreira, CEO of SEALSQ, stated: “Our mission is simple… secure the digital ecosystem with technology that’s built to last. Deploying a Post-Quantum Root of Trust on American soil underscores our dedication to fortifying U.S. cybersecurity and shielding critical ecosystems from quantum-era threats. By uniting U.S.-hosted trust services with our post-quantum hardware, SEALSQ delivers a future-proof, sovereign platform for secure IoT and cloud deployments.”

Starting November 21, developers and organizations will be able to issue quantum-resistant certificates and initiate pilot programs through the INeS IoT Security Platform.
