We Secure IoT.

Teserakt is a Swiss firm specialized in information security and cryptography for complex systems.
We offer thoroughly engineered solutions to protect industrial IoT data and endpoints.


Dynamic Data Protection · E4

Manage clients' rights and automate key distribution using a GUI, CLI, HTTP API, or gRPC API.

Highest security. Data's secrecy and integrity is protected from its producer to its consumers, different keys are used for different type of data and can be rotated automatically.

Dynamic key server. A major pain when deploying encryption at scale is key management. We solve it thanks to a simple interface to manage and distribute keys in an automated fashion.

Maximize performance. Compared to legacy solutions, we minimize resources usage and integration costs thanks to meticulous designs choices in our choice of cryptographic components.

Optimized for MQTT. Our solution is compatible with the IoT platforms of AWS, Azure, Google, and IBM, and can be adapted to other protocols on demand.



Firmware Testing · HALucinator

The most effective security testing tool for IoT firmware, thanks to full host emulation

Finds the bugs that other products won't find. We overcome limitations of static analysis tools thanks to dynamic analysis.

Supports popular platforms. Cortex-M3-based STM32 are supported out-of-the-box.

Simulates real attacks. Thanks to hardware peripherals emulation, we simulate a realistic deployment in a fully virtual way.

Built on state-of-the-art research. We offer this product in partnership with EPFL's HexHive group, co-author of the core technology.
