WISeKey, via its subsidiary WISeSat.Space, and EnduroSat, a provider of software-flexible satellites, as part of their strategy to diversify partners in the industry, are proud to announce signing a Memorandum of Understanding (MoU) to establish a framework aimed at a partnership to extend the development and deployment of ultra-secure, quantum-resilient nanosatellite systems for IoT applications.
The partnership targets integrating SEALSQ secure elements – such as the VaultIC292, VaultIC408, and QS7001 – into satellite payloads and ground-level endpoints. These components facilitate 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 deliver the PQC algorithmic stack and support, while EnduroSat will incorporate these into its satellite and communication platform.
EnduroSat offers 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 outlines future integration of PQC solutions and secure elements into both EnduroSat and WISeSat satellite infrastructures. Furthermore, EnduroSat will also support the design and deployment of WISeSat’s future missions.
This collaboration builds on the success of WISeSat’s deployment of its new-generation PQC-ready nanosatellite in December 2025 and EnduroSat’s track 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,” added Raycho Raychev, founder & CEO of EnduroSat. “We hope to accelerate the introduction and establishment of much stronger encryption capabilities into the satellite industry.”
