Trusted Execution Environments
Hardware-isolated enclaves that keep data encrypted even while it’s being processed.
A Trusted Execution Environment (TEE) is a secure, isolated region of a processor — Intel SGX/TDX, AMD SEV-SNP, ARM CCA, and NVIDIA’s confidential-computing GPUs are all examples — where code and data are protected from the rest of the system, including the cloud provider, the host operating system, and even infrastructure administrators with root access.
Before any sensitive workload runs, remote attestation cryptographically proves the enclave is running exactly the code it claims to be, unmodified, on genuine hardware. That combination — hardware isolation plus verifiable attestation — is what lets PryvX run AI models and joint computations on regulated data inside cloud infrastructure that isn’t otherwise trusted with that data.
How It Works
Trusted Execution Environments in four steps
Encrypt
Data and code are encrypted at the source before being sent anywhere.
Attest
Remote attestation verifies the enclave’s integrity before any data is released to it.
Compute
The workload runs on isolated memory — invisible to the host OS, hypervisor, or cloud admin.
Release
Only the approved, attested output is decrypted and shared back out.
Real-World Applications
Where TEE shows up in production
Confidential AI Inference
Run proprietary or regulated-data models in the cloud without exposing model weights or customer data to the infrastructure provider.
Multi-Party Joint Computation
Parties who don’t trust each other, or a central operator, run a shared computation inside one attested enclave.
Hardware-Backed Key Management
Cryptographic keys and secrets are protected even from a root-privileged attacker on the host.
Regulated Cloud Migration
Move sensitive financial or healthcare workloads to public cloud while keeping data-in-use protection auditable.
