Bill Gross warns on gold momentum as regional bank stocks tumble
Investing.com -- WISeKey International Holding AG (NASDAQ:WKEY) stock rose 2.6% on Wednesday after the cybersecurity firm announced plans to test post-quantum communication technology in space during an upcoming SpaceX launch.
The company’s WISeSat.Space subsidiary will launch a nanosatellite equipped with post-quantum cryptographic technology aboard a SpaceX Falcon 9 rocket from California on November 10, 2025. The satellite will serve as a testbed for post-quantum communication protocols, representing what the company calls a pivotal step in developing quantum-resilient satellite-based IoT connectivity.
The nanosatellite integrates post-quantum cryptographic semiconductors from SEALSQ Corp (NASDAQ:LAES), another WISeKey subsidiary, along with WISeKey’s Root of Trust technology. This combination enables secure end-to-end communication between satellites, ground stations, and connected IoT devices.
"By testing post-quantum communications directly from space, we are showcasing the future of trusted connectivity, one that is both quantum-secure and universally accessible," said Carlos Moreira, Founder and CEO of WISeKey.
The upcoming launch is part of WISeKey’s broader strategy to build a nanosatellite constellation delivering real-time, low-cost, and secure IoT connectivity for sectors including energy, logistics, infrastructure, and climate monitoring. Following this mission, the company plans to deploy four additional post-quantum-ready satellites in 2026.
WISeKey, which trades on both the SIX Swiss Exchange and NASDAQ, specializes in cybersecurity, blockchain, and IoT technologies.
