What is SEALSQ and why you should care

SEALSQ Corp (traded on NASDAQ under ticker LAES) is a French-Swiss technology company that develops post-quantum semiconductors and security chips. In other words — it manufactures hardware designed to withstand attacks even from future quantum computers. The company is part of the Swiss group WISeKey International Holding (NASDAQ: WKEY), which specializes in cybersecurity and digital identity.

SEALSQ today holds 118 security patents, its chips are used by clients in more than 30 countries, and the company works closely on integrating NIST-standardized post-quantum cryptography (ML-KEM/Kyber and ML-DSA/Dilithium algorithms) directly into silicon. The flagship product is the Quantum Shield QS7001 chip with a 32-bit RISC-V architecture and a hardware root of trust.

WISeRobot: The first robots with post-quantum security

On May 20, 2026, SEALSQ together with WISeKey officially launched the WISeRobot.ch platform — a dedicated ecosystem for developing humanoid robots with integrated post-quantum cryptography. And this is not a distant vision: the first proof-of-concept was presented back in January 2026 at the World Economic Forum in Davos, where the robot naturally conversed with attendees, cracked jokes, and took photos with them.

What makes WISeRobot exceptional is its security architecture. Each robot carries a SEALSQ hardware security chip that ensures:

• Verified digital identity of the robot — it cannot be forged or spoofed
• Encrypted communication between robots, satellites, and ground infrastructure
• Protection against quantum attacks — even a future quantum computer would struggle to break this protection
• Secure machine-to-machine payments — robots can "pay" each other for services

The first post-quantum robotics test in space

The most ambitious part of the project is the world's first test of post-quantum secured robotics in space. SEALSQ is connecting its security chips with satellite links — robots can thus securely communicate across continents without the risk of eavesdropping or manipulation. This uses satellite IoT connectivity and PKI (Public Key Infrastructure) operated by SEALSQ.

A key element is the so-called trust stack — a vertically integrated security architecture from the silicon chip up to satellite communication. The company is targeting sectors where security is an absolute priority: defense, healthcare, critical infrastructure, or smart energy.

European technological sovereignty as the main theme

SEALSQ makes no secret that one of its main selling points is European technological sovereignty. At a time when the EU is pushing stricter regulations in the form of the AI Act and when pressure is growing for independence from non-European chip suppliers, SEALSQ represents an alternative to American and Asian security hardware manufacturers.

The company recently successfully integrated the French design firm IC'Alps, thereby strengthening its capabilities in the area of custom ASIC chip design. "We are strengthening European sovereignty in chip design," the company stated in a press release. SEALSQ's investment arm is also actively acquiring stakes in quantum and semiconductor companies — thus building a vertically integrated ecosystem "from sand to satellite".

AI, the quantum threat, and why it matters

Current AI models like GPT-5.5 or Claude Opus 4.7 may dazzle with their capabilities, but from a cybersecurity perspective they also bring new risks. SEALSQ warns that advanced AI can be misused to search for vulnerabilities in classical cryptography — and the combination of strong AI with a future quantum computer could spell disaster for current encryption standards.

That is precisely why SEALSQ bets on hardware security — encryption keys are stored directly in the chip and cannot be extracted via software. The company argues that merely improving AI models (like Claude Opus 4.6) does not eliminate the need for quantum-resistant cryptography — on the contrary, it makes it more urgent.

What the markets say and what the financial reality is

SEALSQ shares trade around $3.52 apiece and the company faces mixed signals: revenue is expected to grow by 55.34% annually, but earnings over the past 5 years have declined by an average of 58.8% per year. The company is still in the investment and proof-of-concept phase — the key will be how quickly it can turn pilot projects into recurring commercial contracts.

For the European context, it is significant that SEALSQ is one of the few publicly listed players in the post-quantum hardware space and can benefit from growing regulations that will require companies to adopt quantum-resistant security. Both the EU AI Act and the NIS2 Directive are creating pressure on organizations to rethink their security architecture.

What it means for the Czech Republic

For Czech companies and institutions, the WISeRobot project is relevant for several reasons. First — the Czech Republic has a strong robotics tradition and ranks among European leaders in industrial automation. The integration of post-quantum security into robotic systems will sooner or later become a standard for businesses in the Czech Republic as well, especially in the automotive industry and logistics.

Second — the Czech National Bank is already investing in AI infrastructure and the question of data center and critical infrastructure security is crucial for Czech regulators. Post-quantum cryptography is not science fiction — NIST has already issued standards and companies should start preparing. Third — European companies like SEALSQ offer an alternative to American and Chinese suppliers, which aligns with the European push for technological autonomy.
