Swiss Military and WISeKey Launch Quantum-Resistant Satellite Security

Last Updated: November 7, 2025By

Strengthening Satellite Security

WISeKey, a leading name in cybersecurity and IoT, has taken a significant step with the Swiss Armed Forces (SAF) to enhance the security of satellite communications. This collaboration, which began in 2022, aims to create a more secure digital environment through innovative satellite technologies. The recent findings from WIRED about the vulnerabilities in global satellite systems highlight the critical need for such advancements. Simple interception techniques can currently expose sensitive communications, making security enhancements imperative.

WISeSat.Space and SAF are developing reliable satellite communication systems designed for military use. This move intends to reduce dependence on external sources, ensuring stronger national security. The project not only includes the creation of small satellites but also leverages post-quantum cryptographic technologies from SEALSQ to secure communications, effectively addressing the vulnerabilities previously highlighted. This initiative aligns perfectly with SAF’s recent strategic updates aimed at bolstering defense capabilities.

Leading the Way in Digital Security

Ludovic Monnerat, heading the new Space Command, emphasizes the importance of this partnership. He notes the dual benefits of increased security and operational flexibility. This cooperation with WISeKey focuses on integrating post-quantum encryption into various communications, which is crucial for maintaining sovereignty over military operations. Carlos Moreira, founding CEO of WISeKey, shares that this collaboration is turning Switzerland into a leader in secure space technologies, showcasing an ideal model for digital and spatial independence.

WISeSat.Space, in collaboration with SEALSQ, is creating a network of secure IoT satellites. These efforts utilize quantum-resistant technologies, ensuring governments and critical infrastructure providers can trust their data’s safety amidst advancing technologies.
