Hardware-Enforced Privacy & Transparency
Tinfoil offers verifiable privacy and integrity guarantees through secure hardware enclaves, cryptographic runtime attestation, and transparency logs for supply-chain security. Your data always stays private and inaccessible to anyone other than you.
(H100, H200, B200)Fast Multi-GPU Inference and Training
Tinfoil is the only platform on the market to offer multi-GPU confidential computing support. Tinfoil uses NVIDIA Hopper and Blackwell GPUs running in confidential computing mode, enabling private AI workloads with near-identical performance to non-private compute.
Secure Hardware Powering Tinfoil
Confidential Computing
Tinfoil leverages confidential computing to create secure enclaves that isolate AI workloads from the host system, the cloud provider, and even Tinfoil itself. Data is encrypted in memory and only decrypted inside the enclave, ensuring that no one can access your data while it is being processed.
Our platform is open-source and combines confidential computing primitives from industry leaders to deliver hardware-enforced privacy with client-side verification tools that make everything automatically verifiable.
Traditional AI vs. Tinfoil AI
See the difference between trusting AI providers with your data and having verifiably private AI using secure hardware enclaves.
Traditional AI Inference
Pinky-Promise Security
With traditional AI providers:
- Your data is only encrypted in transit but not in use
- Providers decrypt your data before processing it with AI models
- Providers can access, analyze, and even train on your data
- Your only protection is legal agreements (DPAs)
Tinfoil AI Inference
Verifiable Hardware-Backed Privacy
With Tinfoil:
- Your data is encrypted directly to the GPU running the AI model
- Models run inside trusted execution environments (TEEs)
- Each model runs in a dedicated confidential computing GPU
- Your data cannot be accessed or shared with third parties
- These security guarantees are cryptographically verifiable
