SEALSQ and WISeSat launch secure satellite on SpaceX mission
SEALSQ, WISeKey and their satellite arm WISeSat.Space have kicked off December with a high-energy milestone: the successful launch of their latest WISeSat secure satellite aboard a SpaceX Falcon 9 Transporter-16 rideshare mission. The deployment therefore strengthens the companies’ ambitions to build a secure, sovereign constellation supporting low-power IoT and next-gen cybersecurity services worldwide.
eeNews Europe readers will find this especially relevant as the region accelerates efforts to secure industrial IoT, critical infrastructure and space-based communications with post-quantum technologies.
Falcon 9 deployment expands WISeSat constellation
The new satellite—inserted into orbit via SpaceX’s Falcon 9—extends WISeSat’s coverage for industrial IoT, encrypted communications, environmental monitoring and infrastructure protection. The mission also reinforces WISeSat’s cooperation with SpaceX as a recurring launch partner.
Carlos Moreira, CEO of SEALSQ, WISeKey and WISeSat, celebrated the achievement, saying: “This successful launch with SpaceX represents a major step forward for WISeSat and for Europe’s capacity to operate sovereign space-based secure communications. The WISeSat constellation is designed to integrate seamlessly with SEALSQ post-quantum chips, ensuring unprecedented levels of trust, privacy, and resilience for the next generation of connected devices.”
Designed as a next-generation platform, the satellite brings several upgrades aimed squarely at high-reliability IoT and mission-critical markets. A software-defined radio (SDR) architecture allows in-orbit reconfiguration to support new or evolving communication standards — an increasingly important capability as IoT protocols diversify. Higher data-rate communication links also promise faster and more secure data transfer for demanding cybersecurity and industrial use cases.
Quantum-safe roadmap accelerates toward 2026
The companies say the launch further cements WISeKey’s positioning at the intersection of IoT, blockchain, cybersecurity and space technology — segments where Europe is pushing hard for technological sovereignty. WISeSat is targeting government, defense and enterprise customers with commercial services designed to scale as the constellation grows.
Beginning with its next launch in early 2026, WISeSat plans to introduce quantum-safe key distribution from orbit. The service is intended to support critical sectors such as energy, transport and smart-city infrastructure while enabling secure onboarding of billions of IoT devices using quantum-resistant digital identities provisioned directly from space.
Technologies from WISeKey, SEALSQ and Hedera continue to converge across the platform, with WISeSat highlighting the use of trusted digital token s — including SEALCOIN — for secure space-to-ground transactions and tokenized satellite services, further enhancing interoperability.
Growing ground network in Europe
To support the expanding constellation, WISeSat has added a new dedicated antenna site in La Línea, Spain, with further installations planned in Switzerland. The upgraded ground infrastructure enhances real-time monitoring, mission control and secure management for upcoming missions as WISeSat pushes toward a broader European footprint.
With this latest launch, the companies sharpen their competitive edge in Europe’s emerging space-cybersecurity ecosystem, aiming to deliver a mix of sovereign capability, commercial scalability and post-quantum readiness.
