SEALSQ and WISeSat Space have signed a binding letter of intent for SEALSQ to acquire satellite capacity and operational services from twelve WISeSat Space satellites in a transaction estimated at $15 million over the next 18 months. This agreement builds upon a recent $10 million investment in WISeSat Space and establishes the initial infrastructure for SEALSQ’s Quantum Spatial Orbital Cloud (QSOC), intended to deliver post-quantum-secured satellite communications and trusted digital identity, the company says. “This letter of intent is a concrete step towards moving QSOC from vision into infrastructure,” said Carlos Moreira, Chairman and CEO of SEALSQ and WISeSat Space.
SEALSQ’s $15 Million Acquisition of WISeSat Capacity for QSOC
WISeSat Space. This arrangement extends beyond simple access. It encompasses the operational framework needed to support QSOC’s development, integrating orbital and terrestrial systems. The initial fleet of twelve satellites, coupled with the ground station, will support the integration of semiconductor security, digital identity and cryptographic-key management across the network. The proposed transaction is structured to align WISeSat Space’s infrastructure development with SEALSQ’s broader strategy of extending its security technologies into space-enabled services, according to the company.
SEALSQ intends to develop and commercialize QSOC’s security-services layer, aiming to create a recurring revenue stream through subscription-based offerings targeted at government and enterprise customers. By securing access to the initial satellite and ground and operational infrastructure for QSOC, the company is laying the foundation for a subscription-based security offering that could complement its semiconductor business and create a new source of recurring revenue.
The company’s focus is on disciplined capital deployment, aligning further investment with technical validation and customer demand to build long-term value for SEALSQ shareholders. This focus suggests a cautious approach to expansion, prioritizing demonstrable results and market demand. The planned services within QSOC encompass post-quantum-secured satellite communications, trusted identity and authentication for connected devices, and secure cryptographic-key provisioning and lifecycle management. Access to quantum-generated randomness and secure data exchange between orbital and terrestrial systems are also central to the platform’s design.

- Access to quantum-generated randomness
- Secure data exchange between orbital and terrestrial systems
WISeSat Space will maintain responsibility for satellite supply, launch and operation of the ground station and mission control, while SEALSQ will concentrate on developing and commercializing the security-services layer. The initial 12 satellites, together with mission control, ground infrastructure and operational support, are intended to provide the foundation on which QSOC’s services can be developed.
Subsequent integration and validation of technologies will be necessary before commencing customer services, contingent upon technical qualification, infrastructure readiness, regulatory authorizations and specific customer requirements. The broader roadmap anticipates the deployment of up to 100 satellites by 2033, though this expansion remains subject to financing, technical validation, regulatory approvals, launch availability, and securing commercial agreements. Moreira further elaborated on the overarching goal: “Our goal is to extend trust from the semiconductor to the satellite, through the ground station and ultimately to the organizations and devices using the network.
Sovereignty requires control over identity, cryptographic keys and the systems that authorize access to data. Through QSOC, we aim to bring these capabilities together across terrestrial and orbital infrastructure, supported by rigorous technical validation.” This ambition to establish a sovereign orbital trust platform highlights the project’s focus on secure, controlled communications and data management.
This letter of intent is a concrete step towards moving QSOC from vision into infrastructure. The initial 12 satellites, together with mission control, ground infrastructure and operational support, are intended to provide the foundation on which QSOC’s services can be developed.
