In a world where everything is connected, trust can no longer be an afterthought.
SandGrain was founded with a single mission: make every connected device authentically trustworthy — from factory floor to end-of-life.
We achieve this by embedding an immutable, hardware-rooted Token directly into every device. Combined with our secure cloud enclave and post-quantum symmetric algorithms, this certificate-free solution guarantees authenticity and sovereignty throughout the entire life-cycle — without provisioning or management overhead.
Behind this breakthrough stands a compact team of world-class experts in hardware security, cryptography, and distributed systems. We move fast, think deep, and obsess over simplicity — because real security should never be complicated.
Together we are building the foundation for a safer, more trustworthy connected future.
Welcome to SandGrain.
