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.

Post-Quantum Secure Semiconductors

SEALSQ develops post-quantum secure semiconductors and hardware root of trust technologies designed to protect connected devices, industrial systems, and critical infrastructure against current and emerging cyber threats.

Our semiconductor platforms integrate advanced security capabilities directly into silicon, including secure boot, secure key storage, cryptographic acceleration, device authentication, tamper resistance, and hardware-based identity protection. These technologies establish trusted device identities and secure communications across IoT, automotive, industrial, energy, and edge computing environments.

SEALSQ’s portfolio includes secure microcontrollers, secure elements, and RISC-V–based security architectures optimized for embedded systems and long-lifecycle connected devices. Our hardware security platforms support secure provisioning, encrypted communications, firmware integrity, and lifecycle protection for modern connected infrastructures.

To address the transition toward quantum-resistant cybersecurity, SEALSQ integrates post-quantum cryptography (PQC) into its semiconductor technologies in alignment with emerging NIST standards, including ML-KEM (Kyber) and ML-DSA (Dilithium). These capabilities help organizations prepare for the future risks posed by quantum computing while maintaining strong protection against today’s cyber threats.

Solutions such as the Quantum Shield QS7001 combine a 32-bit secure RISC-V architecture, hardware Root of Trust, cryptographic acceleration, and post-quantum security capabilities to deliver long-term protection for connected devices, digital identities, industrial IoT systems, and secure communications.

PKI infrastructure and trust services enabling secure device identity, certificate issuance, authentication, and trusted digital ecosystems.

Powered by INeS platform, SEALSQ enables secure onboarding remote attestation, and identity provisioning across IoT frameworks such as Matter and WI-SUN, with local trust gateways such as the Ines Box, enabling secure certificate provisioning in manufacturing environments.

More about PKI

SEALSQ enables secure device onboarding and lifecycle operations from manufacturing to deployment, ensuring trusted provisioning at scale.

Beyond secure key injection and device personalization, SEALSQ provides end-to-end provisioning and validation services, allowing organizations to outsource critical security processes.

With dedicated personalization and testing centers, including its facility in Murcia, SEALSQ supports:

secure key injection and device provisioning
device personalization and configuration
security validation and compliance testing

This industrial capability enables organizations to secure devices before deployment, while simplifying operations and ensuring consistent security governance across large-scale connected infrastructures.

SEALSQ also provides custom ASIC design capabilities for selected high-security and long-lifecycle applications through IC’ALPS.

These services support the development of secure custom semiconductor solutions across industrial, automotive, and IoT environments, with expertise spanning architecture, design, verification, and industrialization.

Security features such as hardware root of trust, secure boot, cryptographic acceleration, and post-quantum cryptography (PQC) can be integrated depending on application requirements.

Discover ASIC solutions

SEALSQ is building a long-term Quantum Security Stack spanning secure semiconductors, digital identity, post-quantum cryptography, trusted communications, and emerging quantum technologies.

This integrated approach extends security from the hardware root of trust to future quantum computing infrastructures, supporting resilient and trusted digital systems for the post-quantum era.

Through strategic investments and technology partnerships, SEALSQ is expanding its capabilities across quantum and post-quantum ecosystems.
