SovereignTEE Ltd
Democratising the technology that keeps data sovereign.
Hardware-attested security, multi-party computation, and universal service interoperability have been available only to the best-resourced teams. We are changing that.
What the name means
Data sovereignty is not a compliance checkbox. It is the architectural guarantee that data is processed only under conditions you control — where it runs, who can see it, what code is allowed to act on it. Sovereignty requires enforcement, not just policy. Without a trustworthy execution environment, the guarantee is only as strong as the promises of whoever operates the infrastructure.
Trusted Execution Environments — Intel SGX, TDX, ARM TrustZone, AMD SEV — are hardware isolation mechanisms that protect code and data from the operating system, the hypervisor, and even the machine operator. A TEE does not ask you to trust the infrastructure provider. It gives you a cryptographic proof of what is running, verifiable by anyone, regardless of who owns the hardware.
The combination is the product: using hardware-attested trusted execution as the mechanism that makes data sovereignty real rather than assumed.
Why this company exists
The pattern that led to SovereignTEE is familiar to anyone who has built distributed systems at scale. Every service boundary demands the same hand-written infrastructure: serialisation, transport plumbing, authentication, callback routing, and lifetime management. None of it is the actual product. All of it accumulates, silently, until it dominates the codebase and the team's time.
Adding hardware attestation — making it cryptographically provable that specific, unmodified code ran on a specific piece of hardware — makes this worse. TEE toolchains are deep, the expertise is rare, and the systems that need these guarantees most are often the ones with the least capacity to build them.
SovereignTEE was founded on the conviction that this capability gap can be closed. The Canopy technology makes boundary infrastructure generated rather than hand-written. The products we are building make hardware-attested trust a deployment option rather than a specialist project. Both should be accessible to any capable development team, not just the largest and best-funded ones.
What we are building
SovereignTEE operates at two levels. Canopy, the open-source foundation, is available now. The commercial products address specific trust and sovereignty use cases that Canopy enables.
Canopy RPC
Open-source universal interface layer. Any language, any transport, any serialisation format. Hardware-attested enclave transports included.
Layer 7 gateway
Policy enforcement at interface granularity. The gateway understands your service contracts and runs in a TEE — its behaviour is hardware-attested to both sides.
Honest broker
A neutral TEE-backed intermediary for two parties who need to compute together without exposing raw data. Both parties attest the code before contributing data.
Hardware-attested DRM
Content and model protection where enforcement is inside a TEE. The operator cannot extract protected assets even with full OS access.
Get involved early
SovereignTEE is forming. Early conversations with potential users and partners directly shape the roadmap. If you have a trust boundary problem that fits this space, we want to hear about it.
