SEALSQ Corp and WISeSat took part in Space Symposium in Colorado, running April 13-16, 2026, with a focus on quantum-resilient Satellite Communications (Satcom). The effort matters because it lays out work for post-quantum services delivered from space.

WISeSat is a subsidiary of WISeKey International Holding Ltd. WISeSat’s satellite communication work targets Internet of Things (IoT) applications, while SEALSQ focuses on semiconductors, Public Key Infrastructure (PKI), and post-quantum technology hardware and software products.

The companies presented the QSOC concept and a roadmap, and they planned to showcase a next-generation 6U post-quantum satellite platform with a first launch scheduled for November 2026. The platform was described as supporting Quantum Key Distribution (QKD), quantum random number generation, and post-quantum digital identity, with Inter-Switch Link (ISL) and other services described as subscription-based offerings.

SEALSQ and WISeSat also described a dual-layer architecture in which WISeSat is expected to manage satellite design, deployment, and mission operations, while SEALSQ intends to operate the quantum cloud layer delivering services. “This marks a pivotal moment in our mission to democratize access to secure space infrastructure,” said Carlos Moreira, Founder and CEO of SEALSQ. “With the launch of QSOC and the integration of post-quantum cybersecurity into our satellite ecosystem, we are building a future-proof foundation for a trusted digital world powered from orbit. By combining advanced quantum-resistant cryptographic technologies with resilient space-based infrastructure, we aim to deliver security that is not only globally accessible, but also independent of vulnerable terrestrial systems. This is about enabling governments, enterprises, and critical industries to operate with confidence in an era defined by accelerating digital transformation and emerging quantum threats.”

SEALSQ and WISeSat said the planned constellation includes a first phase of 15 satellites expected to be launched and fully operational by 2027, and they scheduled a next satellite launch aboard a SpaceX rocket in June 2026.
