WISeKey International Holding AG, a leading global cybersecurity, blockchain, and IoT company, via its subsidiary WISeSat.Space AG, a company that focuses on space technology for secure satellite communication, specifically for IoT applications, and EnduroSat, a leading provider of software-flexible satellites, as part of their strategy to diversify partners in the industry, are pleased to announce the signing of a Memorandum of Understanding (MoU) to establish a framework aimed at achieving a strategic partnership to extend the development and deployment of ultra-secure, quantum-resilient nanosatellite systems for Internet of Things (IoT) applications.
The cooperation targets the integration of SEALSQ secure elements, such as the VaultIC292, VaultIC408, and QS7001, into satellite payloads and ground-level endpoints. These components enable strong hardware-based security and digital identity protection, ensuring encrypted communications and trusted authentication across the IoT satellite network.
The project aims to implement post-quantum cryptographic (PQC) algorithms, aligned with NIST recommendations such as CRYSTALS-Kyber and CRYSTALS-Dilithium, to safeguard against future quantum computing threats. WISeSat will provide the PQC algorithmic stack and support, while EnduroSat will incorporate these into its satellite and communication platform.

EnduroSat brings its expertise in modular satellite design, in-orbit validation, and scalable deployment systems. It will lead the physical integration of SEALSQ secure components into next-generation satellite buses and contribute to the overall mission architecture. WISeSat will support cryptographic integration and field engineering resources, ensuring that each system meets high-security and resilience benchmarks.
The partnership further outlines the future integration of post-quantum cryptographic solutions and secure elements into both EnduroSat and WISeSat satellite infrastructures. EnduroSat will also support the design and deployment of WISeSat’s future missions, ensuring compliance with defined security and performance requirements.
This collaboration builds on WISeSat’s successful deployment of its new-generation PQC-ready nanosatellite in December 2025 and EnduroSat’s proven record of delivering more than 60+ satellites to orbit for institutional, scientific, and commercial customers. The resulting architecture will offer scalable, tamper-proof IoT connectivity services from Low Earth Orbit (LEO), critical for use-cases in logistics, critical infrastructure, defense, and environmental monitoring.
“This partnership with EnduroSat marks a significant step forward in our mission to deliver quantum-resilient, end-to-end secure satellite infrastructure,” said Carlos Moreira, Founder and CEO of WISeKey. “By integrating SEALSQ’s advanced secure elements into the expanding WISeSat constellation, we are building a tamper-proof communications backbone in space. Together with EnduroSat’s modular satellite technology, we are enabling scalable and ultra-secure IoT connectivity services from Low Earth Orbit—critical for securing data and infrastructure in the quantum era.”
“We are excited to initiate this partnership,” said Raycho Raychev, founder & CEO of EnduroSat. “We hope to accelerate the introduction and establishment of much stronger encryption capabilities into the satellite industry.”
