WISeKey placed WISeSat 4.0 into low-Earth orbit on SpaceX’s Transporter-16 mission from Vandenberg, expanding its constellation to 21 spacecraft.
The launch is part of a 2026-2027 hardware renewal cycle, replacing LEO units that typically last about 5 years while scaling the group’s orbital cybersecurity infrastructure.
WISeSat 4.0 carries SEALSQ’s QS7001 secure microcontroller and WISeKey’s hardware Root of Trust to run post-quantum cryptography for sectors including defense, energy and logistics.
The satellite also supports phased deployment of SEALCOIN.AI wallets, enabling on-orbit machine-to-machine transactions and device tokenization without terrestrial relay links.
The deployment feeds WISeKey’s Quantum Spatial Orbital Cloud plan, which targets a 100-satellite sovereign security network by 2033 with 99.9% uptime services for enterprise and government clients.

Securing Space for the Quantum Era: WISeSat 4.0, QSOC, and the 100-Satellite Constellation Vision
Overview
The successful launch of WISeSat 4.0 marks a major step toward building the Quantum Spatial Orbital Cloud (QSOC), a global network for quantum-secure broadband and IoT. WISeSat 4.0 acts as a testbed for SEALSQ Corp.'s advanced security hardware, combining a QS7001 secure microcontroller chip with a hardware-embedded Root of Trust. This setup enables post-quantum cryptography protocols, protecting critical data in sectors like defense, energy, and logistics from future quantum threats. By laying this foundation, WISeSat 4.0 helps move the QSOC vision closer to reality, promising secure, high-speed connectivity worldwide.
