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.

Secure Semiconductors for the Post-Quantum Era

SEALSQ develops secure semiconductor platforms designed to protect connected systems in a rapidly evolving threat landscape.

By embedding security directly into silicon, our technologies establish a hardware root of trust for devices across IoT, automotive, industrial, and critical infrastructure environments.

Our portfolio includes secure microcontrollers, secure elements, and RISC-V–based architectures, combining tamper resistance, secure boot, and advanced cryptographic capabilities to protect sensitive operations and device identities.

As quantum computing progresses, traditional cryptographic algorithms such as RSA and ECC are expected to become vulnerable.
SEALSQ integrates post-quantum cryptography (PQC) into its hardware platforms, aligned with emerging NIST standards, to help organizations anticipate this transition.

These capabilities are implemented in solutions such as the Quantum Shield QS7001 , enabling long-term protection for devices, communications, and digital identities.

SEALSQ delivers end-to-end secure ASIC design services, enabling the development of custom chips tailored to long-lifecycle and high-security applications across IoT, automotive, industrial, and critical infrastructure environments.

Strengthened by the acquisition of IC’ALPS, SEALSQ covers the full design chain — from architecture and RTL design to verification and industrialization — across multiple process technologies.

Security is embedded by design through a comprehensive portfolio of security IPs, including:

hardware roots of trust
secure boot architectures
cryptographic accelerators
post-quantum cryptography (PQC) capabilities

These building blocks enable the development of secure, low-power, and high-performance ASICs, designed to meet the requirements of regulated and long-lifecycle systems.

As quantum computing evolves, SEALSQ integrates PQC-aligned architectures, following emerging NIST standards, to ensure that custom silicon remains resilient over time.

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.
