Geneva, Switzerland, June 22, 2026 (GLOBE NEWSWIRE) – Geneva, Switzerland – June 22, 2026 – SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or “Company”), a company focused on the development and sale of hardware and software products in the fields of semiconductors, PKI and Post-Quantum technologies, and a subsidiary of WISeKey International Holding Ltd (Nasdaq: WKEY; SIX: WIHN) today acknowledges the landmark announcement from the French Agence nationale de la sécurité des systèmes d’information (ANSSI) that from 2027 it will stop certifying security products that lack quantum-resistant encryption, and that all critical infrastructure operators and government agencies will be required to purchase only post-quantum secure solutions by 2030.
SEALSQ views this regulatory milestone as a strong validation of its strategic roadmap. The company’s QS7001 Post-Quantum Secure element, Already validated under NIST SP 800-90B (Entropy Source Validation, ESV Certificate #E333) and designed around NIST standardized post-quantum algorithms, including ML-KEM and ML-DSA, it is today positioned as the hardware root of trust that the market urgently needs now.
Indeed, SEALSQ is experiencing strong commercial momentum with its post-quantum security solutions. The company currently maintains a robust pipeline of more than 150 customers and potential customers for its post-quantum cryptography products, of which more than 30 are already actively integrating SEALSQ’s PQC technology into their devices. This early adoption underlines the growing market appetite for hardware-based post-quantum security.
Regulatory landscape: a turning point for post-quantum security
On June 16, 2026, Samih Souissi, Deputy Director of ANSSI, confirmed at the Quantum Conference in France that the Agency will stop accepting non-post-quantum products for qualification from 2027. Since ANSSI certification is a prerequisite for acceptance by French government agencies and critical infrastructure operators, this policy amounts to a market-wide mandate to retire legacy cryptographic systems on an accelerated timeline.
“This is not just a technical problem,” Souissi said. “It is a matter of governance, industrial planning, regulation and sovereignty.”
The announcement reflects the broader geopolitical urgency surrounding “harvest now, decrypt later” (HNDL) attacks, where adversaries are intercepting encrypted traffic today with the intention of decrypting it once sufficiently powerful quantum computers are available. Estimates cited by ANSSI and its German counterpart (BSI) suggest that a cryptographically relevant quantum computer could emerge before 2040, with a 19-34% probability in the next decade.
QS7001: the hardware foundation of trust, ready now
SEALSQ’s QS7001 is a purpose-built post-quantum Secure Element designed for deployment in semiconductors, IoT devices, critical infrastructure endpoints, satellite payloads and industrial control systems. Key features include:
• NIST Standardized Algorithms: Full implementation of ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium), aligned to FIPS 203 and FIPS 204 respectively.
• NIST SP 800-90B Validated Entropy Source: ESV Certificate #E333 confirms that the hardware random number generator meets the highest entropy standards required for cryptographic key generation.
• Hybrid cryptography architecture: Simultaneous support for classical and post-quantum algorithms, enabling a seamless transition without service disruption – the ‘crypto-agility’ that ANSSI explicitly recommends.
• Root-to-Qubit Stack Integration: The QS7001 resides at the hardware root of SEALSQ’s Quantum Vertical Stack and works in conjunction with the company’s QSOC (Quantum Spatial Orbital Cloud) program and its WISeSat.Space satellite constellation.
• Tamper-resistant hardware: Designed to Common Criteria standards, it provides physical security against side-channel and fault injection attacks, in addition to quantum-resilient cryptography.
Carlos Moreira, CEO of SEALSQ commented: “The ANSSI decision accelerates the timeline for post-quantum security from a long-term consideration to an immediate procurement requirement. For SEALSQ, this is a clear, structural demand catalyst. QS7001 is already shipping, NIST-aligned and designed to be a hardware foundation of trust for the very critical infrastructure and government use cases now moving toward mandatory post-quantum standards We see this translating into a growing pipeline of opportunities across Europe and other regulated markets, and we believe our time-to-market, standard validation and vertically integrated quantum stack position SEALSQ to capture a disproportionate share of this emerging spend.”
Market implications and SEALSQ’s competitive position
The ANSSI mandate, which mirrors parallel initiatives from NIST in the United States and the European Union’s coordinated PQC transition roadmap, creates a compliance-driven procurement cycle with multi-billion dollar implications across the defense, telecommunications, financial services and industrial automation sectors.
Unlike pure software-level post-quantum solutions, the QS7001 meets the fundamental requirement: ensuring cryptographic operations are anchored in tamper-resistant, standards-validated silicon. Software solutions can be counterfeit or compromised at the hardware level; a post-quantum secure element cannot do that.
SEALSQ competes in an emerging market alongside larger semiconductor players, but benefits from several structural advantages:
• Time-to-market: The QS7001 is currently being shipped, while many competitors are still in development.
• Standards Alignment: SEALSQ holds ESV Certificate #E333 under NIST SP 800-90B, a rare distinction that places it directly on the approved path to ANSSI qualification.
• Vertical Integration: From the secure element to satellite-based key distribution via QSOC, SEALSQ offers a complete Quantum Vertical Stack that no competitor has yet replicated.
• European Sovereignty Corner: Headquartered in Geneva and operationally anchored across Europe (including the SEALSQ Quantum Corridor in Murcia, Spain), SEALSQ is positioned as a trusted non-US alternative for European governments sensitive to supply chain sovereignty.
Towards the QSOC: post-quantum security from ground to orbit
The QS7001 is the terrestrial foundation of SEALSQ’s broader Quantum Spatial Orbital Cloud (QSOC) program. With a confirmed QSAT payload launch aboard a SpaceX Falcon 9 in the fourth quarter of 2026, SEALSQ will extend hardware-based post-quantum key distribution to low Earth orbit, providing a satellite-based trust anchor that eliminates the discrete points of failure inherent in terrestrial PKI infrastructure.
This orbital capability is particularly relevant to the use cases that ANSSI considers to be of greatest risk: long-term data confidentiality, cross-border government communications, and critical infrastructure systems where a single cryptographic breach could impact national security.
