WISeSat.Space and SEALSQ Advance Satellite Cybersecurity Hardening as FOSSA Launches New 6U Satellite Aboard SpaceX Falcon 9

Carlos Moreira, CEO of WISeSat.Space

“Building quantum-resilient space infrastructure requires a clear path from technology development to demonstrated performance in orbit. This planned mission represents the next step in that process by providing another platform to evaluate SEALSQ’s security technologies under real operating conditions. Through our collaboration with FOSSA, we aim to apply what we learn from today’s testing to future satellite systems, while preparing for the integration and validation of next-generation post-quantum security.”

Gwenaël Rouy-Poirier, Group CFO of WISeSat.Space

“This launch is a strong illustration of how we intend to execute our strategy: leveraging long-term industrial partnerships and targeted investments to accelerate technology development and validation while maintaining capital discipline. As governments and critical infrastructure operators prepare for the transition to post-quantum security, reinforced by the recent White House Executive Order, we believe that demonstrated performance in orbit will become an increasingly valuable differentiator. Our collaboration with FOSSA allows us to continue building that evidence today, as we prepare for the next generation of WISeSat infrastructure and the commercial opportunities we expect to emerge.”

Julián Fernández, CEO and Co-founder of FOSSA Systems

“Our relationship with WISeSat goes well beyond individual satellite launches. We have worked together for several years to bring advanced semiconductor security technologies into space, and our new 6U platform creates further opportunities to expand that work. With the next phase of our collaboration, we intend to move toward more systematic in-orbit testing and validation, building the technical experience required for increasingly sophisticated secure satellite applications.”
