Because digital security is only as strong as its weakest layer, SEALSQ is building a Vertical Quantum Security Stack integrating secure semiconductors, post-quantum cryptography, digital identity infrastructure, and trusted connectivity.

By combining these layers into a unified architecture, SEALSQ enables organizations to protect devices, communications, and data, from silicon roots of trust to global networks, in the post-quantum era.

About us

Products & Services

SEALSQ develops quantum-resistant secure microcontrollers, secure RISC-V platforms, and advanced PKI-based Trust Services designed to protect devices from today’s cyber threats and tomorrow’s quantum attacks. Built with hardware-level security, crypto accelerators, post-quantum algorithms, and secure lifecycle management, our Secure MCUs and Trust Services form the foundation of reliable device identity, secure provisioning, and end-to-end authentication across IoT, automotive, industrial, and smart home ecosystems.

At the core of our quantum-security strategy is the SEALSQ Quantum Lab — our dedicated research and development center focused on integrating NIST-approved post-quantum cryptography (PQC) into silicon, secure firmware, and cloud services. The Quantum Lab accelerates innovation in quantum-resistant architectures, cryptographic validation, and compliance frameworks, ensuring that our customers can deploy devices that remain secure well beyond the arrival of large-scale quantum computing.

Custom Semiconductor Design (ASIC)

Strengthened by the acquisition of IC’ALPS, SEALSQ delivers end-to-end secure ASIC design services, from architecture and RTL design to verification and industrialization, across multiple process technologies.

Security is embedded by design, integrating hardware roots of trust, secure boot, cryptographic accelerators, and post-quantum–ready architectures, enabling secure, low-power, and high-performance ASICs tailored to long-lifecycle and regulated applications.

Discover ASIC solutions

As quantum computing advances, traditional cryptographic algorithms such as RSA and elliptic-curve cryptography will eventually become vulnerable. SEALSQ develops post-quantum cryptographic technologies aligned with emerging NIST standards to help organizations prepare for this transition.

These capabilities are integrated into SEALSQ’s security platforms, including the Quantum-Resistant Secure Element QS7001, enabling long-term protection for devices, communications, and digital identities in the post-quantum era.

Quantum Lab

SEALSQ delivers cloud and edge-based PKI and Trust Services for secure device identity, certificate issuance, key provisioning, and lifecycle management at scale. Aligned with Common Criteria, FIPS, and global IoT security frameworks, our platform enables zero-touch provisioning, secure onboarding, and remote attestation, including Matter-compliant ecosystems, with post-quantum readiness built in.

The INeS Box extends PKI into manufacturing and regulated environments, providing an on-premises trust gateway for local key custody and controlled provisioning. Integrated with AWS IoT Core and Azure IoT Hub / DPS, SEALSQ secures device-to-cloud authentication against cloning, tampering, and unauthorized access.

More about PKI

SEALSQ delivers secure personalization and industrial test services to ensure device identity and cryptographic material are correctly instantiated and validated during manufacturing. Capabilities include secure key injection, device personalization, and security validation, aligned with Common Criteria and FIPS requirements.

In 2025, SEALSQ partnered with Quantix Edge Security to establish Spain’s first post-quantum semiconductor personalization center, a €25 million initiative supporting sovereign, high-assurance manufacturing environments.
