Last Updated: October 19, 2025By

Exciting Launch for WISeSat.Space

Fasten your seatbelts because something exciting is set to happen on November 10, 2025. WISeKey International Holding Ltd, the renowned cybersecurity maestro, is sending its subsidiary, WISeSat.Space, into the cosmos with a nanosatellite launch. This satellite, outfitted with SEALSQ’s post-quantum cryptographic technology, will hitch a ride on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

This mission is no ordinary space venture. It aims to test post-quantum communication protocols, a critical step in making our satellite-based IoT communications safe from advanced cybersecurity threats, especially those posed by quantum computing. Through this initiative, WISeSat is reinforcing its promise to build secure and sustainable communication frameworks in space.

Space-Age Security Solutions

The WISeSat satellite doesn’t just boast cutting-edge technology; it’s a trailblazer in security. Thanks to SEALSQ’s advanced post-quantum cryptographic semiconductors and WISeKey’s solid Root of Trust, it promises ironclad communications between satellites, ground stations, and IoT devices. It’s one of the first to test post-quantum encryption in real-time orbital settings, showing a significant leap forward for satellite technology.

Carlos Moreira, the founder and CEO of WISeKey, sees this mission as a vital step into the future. “Advancing post-quantum communications from space showcases the future of secure connectivity. We are committed to building a resilient infrastructure to guard against emerging cybersecurity threats,” he assures.

Why WISeSat’s Initiative Matters

WISeSat isn’t just aiming high; it’s looking to revolutionize connectivity. Their satellite constellation hopes to offer affordable, secure IoT connectivity that spans energy, logistics, and even climate monitoring sectors. By utilizing advanced encryption and decentralized networks, WISeSat seeks to establish tamper-proof communication systems, crucial for global operations.

The upcoming launch isn’t the end of their journey, as four more satellites are planned for 2026, each with more advanced post-quantum technology.
