Company Description
SEALSQ Corp (NASDAQ: LAES) is a semiconductor and security technology company focused on post-quantum cryptography, secure microcontrollers, and Public Key Infrastructure (PKI). The company develops and sells hardware and software products that integrate semiconductors, PKI, and provisioning services with an emphasis on quantum-resistant cryptography designed to address the security risks posed by emerging quantum computing capabilities.
According to SEALSQ, its technology is engineered to protect sensitive data and critical systems as traditional cryptographic methods such as RSA and Elliptic Curve Cryptography (ECC) become increasingly vulnerable to quantum attacks. By embedding post-quantum cryptography directly into semiconductor devices, SEALSQ aims to provide long-term protection for digital identities, connected devices, and infrastructure across multiple industries.
Core business and technology focus
SEALSQ describes itself as a provider of Post-Quantum Technology hardware and software solutions. Its platform brings together:
- Semiconductors – secure microcontrollers, secure elements, and post-quantum-ready chips.
- PKI and provisioning services – lifecycle management of digital certificates, device identity, and secure provisioning.
- Quantum-resistant cryptography – algorithms and architectures designed to remain secure against future quantum computers.
The company highlights the development of Post-Quantum Semiconductors that can be used in applications such as multi-factor authentication tokens, smart energy, medical and healthcare systems, defense, IT network infrastructure, automotive, and industrial automation and control systems. These products are intended to safeguard critical systems and data against quantum-enabled threats.
Post-quantum secure chips and product ecosystem
SEALSQ has reported the commercial launch and market adoption of its Quantum Shield QS7001™ secure microcontroller, a post-quantum secure chip positioned as a hardware root of trust. In SEC filings, the company notes that the QS7001 and its QVault TPM trusted platform module are part of a broader opportunity pipeline for quantum-resistant security solutions.
The company also references its VaultIC secure hardware family and post-quantum secure processors such as QVault-TPM, as well as PQC-ready secure elements and cryptographic processors. These components are designed to provide hardware-anchored security, protect long-lived data, and support secure identity and authentication in devices and networks.
Industry applications and use cases
SEALSQ states that its post-quantum semiconductor and PKI technologies are used or targeted in a range of sectors, including:
- Smart energy and smart metering – securing advanced metering infrastructure and smart meters, with deployments that include partnerships such as Landis+Gyr and other utilities.
- Medical and healthcare systems – protecting sensitive health data and connected medical devices.
- Defense and critical infrastructure – securing systems where long-term confidentiality and integrity are essential.
- IT network infrastructure – embedding secure roots of trust into networking and security equipment.
- Automotive and industrial automation – enabling secure communication and control for vehicles and industrial systems.
- IoT ecosystems and smart home devices – supporting device identity, firmware integrity, and standards such as Matter-compliant device attestation through its INeS PKI platform.
Through these use cases, SEALSQ positions its technology as a way to address "harvest-now-decrypt-later" risks, where data captured today could be decrypted by future quantum computers.
Quantum strategy and ecosystem
SEALSQ presents a broader quantum strategy that extends beyond cryptography into quantum-enabled infrastructure. The company has communicated plans and initiatives related to:
- Silicon-based quantum computing using CMOS-compatible semiconductor technologies as part of a strategic plan for 2026–2030.
- A dedicated Quantum Fund designed to support quantum and post-quantum technologies, including investments in companies such as IC’ALPS, ColibriTD, EeroQ, WISeSat, WeCan, and Quantix Edge Security.
- Collaborations and potential transactions with quantum hardware firms, such as a non-binding memorandum of understanding regarding a potential investment in Quobly, a developer of silicon-based quantum processors.
- Participation in initiatives like the “Year of Quantum Security 2026” and organizing quantum-focused roundtables and events.
SEALSQ describes its role as building a bridge between the classical digital world and the quantum era, with a focus on trust, security, and governance for quantum-enabled systems.
