WISeKey International Holding, a global cybersecurity, AI and IoT company, has announced that its subsidiary, WISeSat has released the satellite launches schedule for 2025, marking an advancement in secure satellite-based IoT communications.
The next confirmed launch is scheduled for June 2025 with SpaceX, deploying next-generation WISeSat satellites designed with post-quantum-ready security to protect against future cyber threats, followed by another one in October and a third one in December. This launch series serves as a proof of concept, integrating WISeKey’s trusted Root of Trust with SEALSQ’s cutting-edge Post-Quantum Chips, ensuring unmatched cybersecurity resilience in an evolving digital landscape. These satellites also incorporate incremental technology derived from the SEALSQ quantum roadmap, using innovations from SEALSQ’s partner and startup investment program to enhance security, performance and efficiency.

The WISeSat constellation continues to expand, offering real-time, ultra-secure connectivity for IoT devices across industries worldwide. In response to the escalating cyber risks posed by quantum computing advancements, WISeSat reinforces WISeKey’s commitment to pioneering a resilient cybersecurity infrastructure.
Carlos Moreira, the founder and CEO of WISeKey, emphasised the importance of this initiative by noting: “These new launches represent a major step forward in securing IoT communications for the future. By integrating SEALSQ’s Post-Quantum Chips with WISeKey’s trusted Root of Trust, we are ensuring that WISeSat remains a leader in satellite cybersecurity. Our goal is to provide a quantum-resistant, globally connected IoT ecosystem that meets the security challenges of tomorrow.”
As the satellite IoT communications division of WISeKey, WISeSat, was established to meet the growing demand for secure, real-time IoT connectivity across critical industries, including logistics, agriculture, energy and infrastructure management. WISeSat was established as part of WISeKey’s broader strategy to provide security in the era of quantum computing. Traditional IoT networks face increasing vulnerabilities, and WISeSat addresses these risks by delivering a global, satellite-based solution that combines secure connectivity with post-quantum cryptographic protection.
Building on the success of its prior missions, WISeKey is preparing multiple WISeSat deployments throughout 2025, which will:
- Expand the WISeSat satellite network to increase coverage, bandwidth, and redundancy.
- Integrate AI-driven analytics for enhanced security monitoring and real-time data processing.
- Develop hybrid terrestrial-satellite solutions to ensure seamless, ultra-secure IoT connectivity.
WISeSat.Space AG is at the forefront of secure IoT connectivity and climate change monitoring, using advanced satellite technology to deliver cost-effective, secure global communications. The WISeSat constellation supports key applications such as environmental monitoring, disaster management and sustainable development. By integrating satellite-generated data with advanced climate models, WISeSat plays a crucial role in improving environmental intelligence and developing strategies to combat climate change.
As the cyber and environmental landscapes continue to evolve, initiatives like WISeSat’s IoT satellite constellation will be critical in shaping a more resilient, secure and sustainable future. With multiple launches planned for 2025, including the next confirmed mission with SpaceX in June, WISeKey remains at the forefront of securing the IoT ecosystem through space-based technology, leading the way toward a quantum-secure digital world.
The June launch will include a PoC that will demonstrate SEALCOIN’s potential to facilitate decentralised space transactions in the growing Internet of Things (IoT) ecosystem. Using the SEALCOIN platform, the PoC will enable satellite-initiated transactions to IoT devices without human intervention. The tokens, based on Hedera Decentralised Ledger Technology (DLT), ensure secure, transparent and tamper-proof exchanges, driving the creation of a scalable Transactional IoT (t-IoT) infrastructure.
In June, SEALSQ will launch a Proof of Concept (PoC) showcasing SEALCOIN’s potential in decentralised space transactions within the expanding Internet of Things (IoT) ecosystem.
- The PoC will enable satellite-initiated transactions with IoT devices without human intervention, establishing a seamless, autonomous data and value exchange mechanism.
- SEALCOIN tokens, built on Hedera’s Decentralised Ledger Technology (DLT), ensure secure, transparent and tamper-proof transactions.
- This initiative will pave the way for a scalable Transactional IoT (t-IoT) infrastructure, enhancing efficiency and security in space-based IoT communications.
This breakthrough aims to redefine machine-to-machine (M2M) transactions in sectors like smart cities, logistics and remote sensing, opening new possibilities for secure, decentralised IoT applications beyond Earth.
