WISeKey, WISeSat and Latitude Join Forces to Prepare a Future Secure IoT Satellite Constellation

WISeKey International Holding Ltd (“WISeKey”), a leading global cybersecurity, blockchain, and IoT company, its subsidiary WISeSat.Space AG  (“WISeSat”) which focuses on space technology for secure satellite communication, specifically for IoT applications, and Latitude, a French aerospace company designing, manufacturing and operating an orbital launch vehicle, announced the signing of a commercial agreement to assess the orbital launch of WISeSat’s planned secure IoT satellite constellation. This agreement represents another step forward in WISeSat’s strategy which aims at deploying 100 satellites by 2029, creating a global constellation dedicated to secure IoT connectivity, environmental monitoring, and critical infrastructure management for commercial and institutional customers. It also comes at a moment when demand for low-latency and highly secure space-based connectivity is accelerating worldwide.

Secure IoT enters a new era: space as digital infrastructure

Global demand for IoT connectivity, whether for environmental monitoring, critical infrastructure oversight, risk prevention, or industrial processes, is growing exponentially. To address this need, WISeSat, is developing an IoT satellite constellation designed to deliver global, cost-efficient, and highly secure connectivity.

These satellites will embed several of WISeKey’s core cybersecurity technologies, including:

• quantum-resistant security protocols,
• strong authentication mechanisms for IoT devices, and
• end-to-end protected data transmission between space and ground.

WISeSat’s plan to deploy approximately 100 satellites by 2029, aims to build a resilient and sovereign data infrastructure able to support environmental, industrial, and governmental applications.

WISeSat selects Latitude to enable a fast and controlled constellation deployment
To build this orbital architecture, WISeSat relies on partners capable of providing dedicated, flexible launch services compatible with a wide range of orbital parameters. In this context, WISeSat has chosen to work with Latitude in developing Zephyr Launcher, a small orbital rocket that meets the deployment needs of modern constellations.

With a payload capacity of up to 200 kg to SSO orbit, Zephyr Launcher offers satellites’ operators a responsive, flexible, and dedicated access-to-orbit solution, launching from multiple spaceports with high-cadence capability.

This agreement marks the initiation of a joint collaboration to secure a fast, controlled, and mission-compliant deployment aligned with the stringent security requirements of critical IoT applications.

Carlos Moreira, CEO of WISeKey noted, “This strategic collaboration represents a major leap toward global connectivity that’s both intelligent and secure. By deploying 100 satellites by 2029 in cooperation with Latitude, we ain to create a resilient and sovereign data infrastructure to support environmental, industrial, and governmental applications. Our constellation will enable secure IoT connectivity, advanced environmental monitoring, and critical infrastructure management, empowering organizations worldwide to operate more sustainably, efficiently, and independently. Together, we’re building the digital backbone of a smarter and more resilient planet.”

A structuring partnership for the future of secure IoT
Beyond its technical dimensions, this agreement reflects a broader shift: the rise of a new generation of digital infrastructure operating at the converge of space, cybersecurity, and IoT.

Backed by WISeKey, WISeSat aims to build an orbital architecture capable of securing IoT communications worldwide, at a time when data protection is becoming critical for both enterprises and governments. Latitude, in parallel, is developing a launch service designed to provide constellation operators with the responsiveness, flexibility, and mission control required for rapid service deployment.

By combining these complementary capabilities, WISeSat and Latitude are paving the way for an unprecedented convergence between terrestrial and space-based infrastructure, a key enabler for the expansion of secure IoT services. Their partnership will support the development of essential applications, from environmental monitoring to industrial network protection, while offering a sovereign, sustainable, and scalable response to the world’s rising connectivity needs.

Together, the two companies are laying the foundations for a new generation of digital infrastructure: more resilient, more secure, and capable of evolving with the major technological challenges of the coming decade.

Adeline Pitrois Chief Commercial Officer of Latitude noted, “This agreement with WISeSat confirms Latitude’s ability to support constellation operators with a reliable, flexible, and dedicated launch service. Zephyr Launcher is designed to meet the operational and security requirements of modern IoT missions, enabling controlled and efficient deployment. We are pleased to support WISeSat in this important phase of its constellation program.”
