Wisekey International Holding AGWISeKey's subsidiary WISeSat.Space invests in FOSSA, reinforcing its satellite infrastructure roadmap.

WISeKey International Holding announced that its subsidiary WISeSat.Space has participated in the latest financing round of FOSSA Systems, a Spain-based small-satellite company. The investment builds on a four-year partnership that began in 2021, during which FOSSA contributed to WISeSat’s early satellite missions and helped establish flight heritage across 25 launched low Earth orbit satellites, with 8 currently in operation. WISeSat views the move as reinforcing its European secure satellite infrastructure roadmap, which aims to provide capacity for secure communications, IoT connectivity, and future post-quantum use cases. The investment aligns with WISeKey’s broader ecosystem, including SEALSQ’s post-quantum semiconductor capabilities, though FOSSA is not part of the SEALQUANTUM.COM fund. WISeSat expects the relationship to support next-generation satellite platforms, launch requirements, and ground-segment architecture as it transitions from pilot missions to more advanced orbital infrastructure.
