SEALSQ, WISeKey and Swiss Armed Forces Advance Quantum-Secure Satellite Security

Geneva, Switzerland, Nov. 04, 2025 (GLOBE NEWSWIRE) -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, together with its parent company WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading Swiss cybersecurity, AI, and IoT company, and WISeSat.Space which focuses on space technology for secure satellite communication, today provided an update on the evolution of its collaboration with the Swiss Armed Forces (SAF). This partnership, initiated in 2022, continues to advance Switzerland’s sovereign space and cybersecurity infrastructure by combining secure IoT satellites with trusted digital identity and post-quantum cryptographic technologies.

Recent coverage by WIRED revealed a stark vulnerability in the global satellite communications ecosystem: with just a few hundred dollars’ worth of off-the-shelf equipment, researchers intercepted unencrypted calls, texts, and sensitive military and corporate data being broadcast via geostationary satellites. (wired.com) The article underscores how many satellite “backhaul” links, especially those serving remote or critical infrastructure, remain unprotected, exposing vital information to trivial interception.

In direct response to such threats, WISeSat.Space’s work with the SAF supports the development of secure, sovereign satellite-based communications, reconnaissance, and navigation systems for military organizations. These initiatives aim to reduce reliance on foreign providers and intergovernmental projects, thereby enhancing national resilience, operational autonomy, and cybersecurity.

Since the signing of the initial agreement, WISeSat.Space and the SAF have jointly conducted research, development, and mission testing on small-satellite and secure communications capabilities, including Low Earth Orbit IoT (LEO-IoT) and Internet of Battlefield Things (IoBT) applications. The collaboration has now evolved to integrate SEALSQ’s post-quantum semiconductors and WISeKey’s Swiss Root of Trust, ensuring quantum-resilient encryption and authentication for satellite-to-ground and inter-satellite communications. These quantum-secured WISeSat satellites directly address the vulnerabilities exposed in the WIRED report, creating a zero-trust orbital network that guarantees encryption from end to end.
