What is SEALSQ?

SEALSQ develops and supplies secure microcontrollers, hardware-based security platforms, and trust services designed to protect connected devices against current and future cryptographic threats. The company focuses on integrating post-quantum cryptography (PQC) into silicon, offering semiconductor products such as secure elements, RISC-V-based architectures, and custom ASICs. These components provide hardware-level roots of trust, tamper resistance, secure boot, and cryptographic acceleration. The company’s products are aimed at applications in IoT, automotive, industrial systems, and smart home devices.

In addition to hardware, SEALSQ operates a Quantum Lab dedicated to implementing NIST-standardized post-quantum algorithms into its products. The company also provides public key infrastructure (PKI) and trust services, including secure device identity provisioning, certificate issuance, and lifecycle management through its INeS platform and local trust gateways. Its offerings are designed for manufacturers and organizations that require certified security across device lifecycles, from manufacturing to deployment. SEALSQ is a subsidiary of WISeKey (Nasdaq: WKEY) and trades publicly under the ticker LAES.
