WISeSat.Space and SEALSQ Advance Satellite Cybersecurity Hardening as FOSSA Launches New 6U Satellite Aboard SpaceX Falcon 9
This new FOSSASAT-2E27 launch expands opportunities for rigorous in-orbit testing of WISeSat SEALSQ security technologies to strengthen satellite resilience against emerging cyber and quantum threats
Longstanding strategic partnership, supported by successive investments, targets further technology validation across up to six satellite missions as demand for quantum-resistant security is expected to accelerate

GENEVA, Switzerland, October 20, 2026 — WISeSat.Space Holdings Corp. (Nasdaq: SAIQ) ("WISeSat.Space" or "WISeSat") today announced a new milestone in its secure space infrastructure strategy, following the successful launch and deployment of FOSSASAT-2E27, a new-generation 6U satellite developed and operated by its longstanding strategic partner FOSSA Systems ("FOSSA"), aboard SpaceX's Falcon 9 Bandwagon-5 mission from Cape Canaveral, Florida.
Equipped with VaultIC secure-element technology from SEALSQ Corp. (Nasdaq: LAES), the spacecraft provides a further opportunity to advance WISeSat's technology-validation roadmap, building on years of cooperation to integrate hardware-based cybersecurity into satellite systems.
The mission illustrates the value of a strategic industrial relationship established in 2021 through WISeQey Corp's (SIX/Nasdaq: WQEY) original investment in FOSSA and reinforced by WISeSat's participation in FOSSA's latest financing round in June 2026.
Under an extended technical collaboration covering up to six selected FOSSA satellite missions, WISeSat and FOSSA intend to pursue more systematic and demanding in-orbit testing protocols for SEALSQ security technologies, including repeatable functional testing, performance monitoring and analysis under actual space operating conditions.
The collaboration is expected to support the progressive validation of VaultIC secure elements and, subject to technical readiness and integration, the next-generation QS7001 post-quantum secure element. Selected experiments are intended to include six-month in-orbit testing and monitoring periods, generating technical data to inform future satellite security architectures.
Positioning for Growing Post-Quantum Security Requirements
The expanded collaboration comes as governments and critical infrastructure operators prepare for the transition toward quantum-resistant cybersecurity. In particular, U.S. Executive Order 14412, issued on June 22, 2026, establishes an accelerated framework for federal migration to post-quantum cryptography, including requirements scheduled for implementation from 2030 onward.
WISeSat believes that building practical flight heritage and strengthening in-orbit validation today will be important to addressing future requirements for trusted satellite communications, including sovereign, defense and critical-infrastructure applications.
Carlos Moreira, CEO of WISeSat.Space, commented: "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, added: "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, commented: "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."
The FOSSASAT-2E27 mission also incorporates software-defined radio capabilities, onboard AI processing and a separate electric-propulsion demonstration, reflecting the technological evolution of FOSSA's satellite platforms.
The collaboration complements WISeSat's broader roadmap to develop next-generation, quantum-resilient orbital infrastructure intended to support SEALSQ's planned Quantum Spatial Orbital Cloud (QSOC) and other secure communications applications.
