SEALSQ and WISeSat to Showcase Breakthrough Post-Quantum Satellite Technology at the 40th Annual Space Symposium in Colorado Springs

Geneva, Switzerland, April 07, 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 WISeSat.Space, a subsidiary of WISeKey International Holding Ltd. ((SIX: WIHN, NASDAQ:WKEY), today announce their participation in the 40th Annual Space Symposium, taking place next week in Colorado Springs, Colorado.

During the event, WISeSat and SEALSQ will unveil their latest advancements in post-quantum satellite technology, highlighting how the WISeSat constellation is paving the way for a new era of secure, sovereign space-based infrastructure.

The WISeSat constellation is designed to provide highly secure, space-based connectivity for IoT devices, enabling data transmission protected against both classical and future quantum computing threats. The deployment of this constellation represents a major leap forward in the development of quantum-resilient cybersecurity solutions for governments, critical infrastructure operators, and private sector partners worldwide.

The companies are also using the opportunity to establish new strategic partnerships with leading aerospace stakeholders, research institutions, and government agencies. These partnerships will support the expansion of the WISeSat constellation, with the next satellite scheduled to launch aboard a SpaceX rocket in June 2025.

As quantum computing advances, traditional encryption methods are at risk of becoming obsolete. The ability of quantum computers to break today's most widely used cryptographic systems poses a significant threat to data security, digital identities, and critical infrastructure across the globe.

Post-quantum cryptography (PQC) is the next frontier in cybersecurity, and by deploying PQC directly from low-Earth orbit satellites, WISeSat is enabling a sovereign, tamper-resistant, and globally accessible security layer. This approach provides end-to-end quantum-resistant protection for connected devices and communications, especially in regions where terrestrial infrastructure is limited or exposed to geopolitical risks.

"This marks a pivotal moment in our mission to democratize access to secure space infrastructure," said Carlos Moreira, Founder and CEO of SEALSQ. "By integrating post-quantum cybersecurity into our satellite ecosystem, we are building a future-proof foundation for the trusted internet of things from orbit."

The presence of WISeSat and SEALSQ at the Space Symposium underscores their joint commitment to securing space communications in the quantum era, in alignment with the European IRIS² initiative and global digital sovereignty strategies.
