WISeSat is the satellite IoT subsidiary of WISeKey International, a Swiss-based cybersecurity and digital identity company. WISeSat combines low Earth orbit satellite connectivity with embedded security technologies, aiming to provide secure, low-power IoT communications for global deployments.
Unlike many satellite IoT operators that focus purely on connectivity, WISeSat positions security, cryptographic identity and device trust as core elements of its network architecture.
Technology
WISeSat operates a constellation of small satellites in low Earth orbit, using software-defined radio (SDR) technology to support flexible and upgradable communications payloads. The system is designed to enable low-power communications suitable for IoT sensors and devices transmitting small data packets.
A distinguishing feature of WISeSat’s technology stack is its integration with WISeKey’s existing cybersecurity and digital identity platforms. This includes hardware-based root-of-trust elements, device authentication and encryption mechanisms designed to secure IoT data from the sensor through to the application layer.
The network architecture is optimised for low data rates and long battery life, rather than continuous or high-bandwidth connectivity.
Coverage
WISeSat is designed to provide global coverage via its LEO satellite constellation, enabling IoT connectivity in areas without terrestrial mobile or LPWAN infrastructure. The system is intended to support deployments in remote, industrial, maritime and geographically isolated environments.
As the constellation expands, coverage density and service availability are expected to improve, allowing increased message frequency and reliability for supported use cases.
Service Offering
WISeSat provides satellite IoT connectivity for low-power devices generating small volumes of data. Typical use cases involve periodic telemetry, status updates and monitoring data rather than real-time or high-throughput communications.
In addition to connectivity, WISeSat’s service offering emphasises secure device onboarding, identity management and encrypted communications. This makes the platform particularly suited to applications where data integrity, authenticity and protection against tampering or interception are critical.
The service is designed to support long device lifetimes and mass deployment scenarios, with a focus on robustness and resilience rather than consumer-grade throughput.
Target Markets and Use Cases
WISeSat targets sectors where secure satellite IoT connectivity is a functional requirement rather than a convenience. These include:
- Critical infrastructure monitoring
- Industrial and energy-sector IoT deployments
- Environmental and remote asset monitoring
- Logistics and asset tracking in areas without terrestrial coverage
- Smart city applications requiring strong device identity and authentication
The platform is particularly suited to deployments where cybersecurity, regulatory compliance or data assurance are as important as connectivity itself.
Position in the Satellite IoT Ecosystem
WISeSat occupies a distinct position within the satellite IoT ecosystem, sitting at the intersection of satellite connectivity, device identity and IoT cybersecurity. While not positioned as a high-throughput or mass-consumer IoT network, it addresses a growing demand for secure, trusted and resilient IoT communications delivered via satellite.
