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.

Public Key Infrastructure & Trust Services

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.

Personalization & Test

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.
