Secure enclave solutions for confidential AI inference

If you need to run AI inference while keeping prompts, proprietary model weights, and generated outputs protected from cloud administrators or infrastructure operators, I recommend evaluating GPU-backed confidential computing with hardware attestation.

The key distinction is that a traditional CPU enclave may protect application memory without protecting the data once it reaches a GPU. For modern LLM inference, look for a solution that protects both CPU and GPU execution, and lets you independently verify that the correct software is running before releasing secrets.

The strongest options to evaluate

1. NVIDIA Confidential Computing

(Best for GPU inference)

Hardware-backed protection for AI workloads using supported NVIDIA GPUs, including Hopper H100 and newer architectures. Particularly relevant if you need to protect model weights and prompt data while the GPU is actively computing.

GPU memory protection and hardware attestation.
Suitable for high-performance LLM inference.
Can be combined with a confidential CPU VM.

2. Microsoft Azure Confidential GPU VMs

(Managed cloud)

Azure's NCCadsH100v5 VM family combines AMD SEV-SNP CPU protection with an NVIDIA H100 confidential GPU. This is a practical starting point if you want to deploy an inference service without building the entire hardware stack yourself.

Confidential CPU and GPU execution.
Cloud VM deployment and integration with Azure services.
Verify regional availability and current feature status before choosing a SKU.

Explore:

3. Confidential Containers + Trustee

(Best open-source foundation)

An open-source framework for running containerized workloads inside hardware-backed confidential VMs, with attestation and secret provisioning through Trustee.

Supports Intel TDX and AMD SEV-SNP, among other platforms.
Fits Kubernetes and self-managed infrastructure.
Can support NVIDIA confidential GPUs on compatible hardware.

This is especially attractive if you want control over the inference stack and the attestation policy rather than relying entirely on a managed AI service.

4. Confidential AI — Confidential Inference

A specialized option to evaluate if you want a confidential inference endpoint rather than assembling and operating all the infrastructure yourself. Its published documentation describes confidential GPU hosting, attestation, and pay-per-token inference.

Hosted inference with hardware-backed isolation.
Published options for dedicated GPU capacity.
Review the precise attestation boundary, deployment region, retention terms, and supported models before production use.

Recommended architecture

For a production LLM service handling sensitive data, I would design the system around this flow:

Client application

Encrypt prompts and verify the service's identity

Remote attestation and key release

Verify hardware, boot measurements, software image and policy before releasing decryption keys

Confidential CPU + GPU environment

Decrypt model weights and prompts inside the protected execution boundary; run inference on an attested confidential GPU

Protected response path

Encrypt outputs for the authorized client; prevent sensitive data from entering logs or telemetry

A critical requirement is that key release depends on successful attestation. Merely launching a confidential VM is not enough. The system should verify the GPU as well as the CPU, and bind the authorization policy to the approved workload and model artifacts.

How I would choose

Your priority	Starting point
Fastest route to GPU-backed confidential inference	Azure Confidential GPU VMs
Maximum control over the inference stack	NVIDIA Confidential Computing
Kubernetes, portability and open-source controls	Confidential Containers + Trustee
Managed confidential inference API	Confidential AI
CPU-only, small trusted code boundary	SGX or another CPU TEE, subject to workload requirements

One caution: AWS Nitro Enclaves is useful for isolating sensitive CPU-side services and managing keys, but it should not be assumed to provide the same end-to-end GPU-memory confidentiality as a confidential GPU architecture.

Three questions to narrow this to the right solution

1. Where do you want to run inference?

Public cloud

On-premises / private data center

Either, preferably portable

2. What are you protecting?

LLM inference with GPU acceleration

CPU-only inference or small models

A confidential API around a third-party AI model

3. Who must be unable to access the data?

Cloud provider and infrastructure administrators

Other tenants and compromised host software

Both, plus independent verification of the deployed model and code

Expected scale (optional)

Prototype / proof of concept

Production, moderate traffic

High throughput / multiple GPUs

Running confidential AI inference requires isolating data in use (both user inputs/prompts and proprietary model weights) using hardware-enforced Trusted Execution Environments (TEEs). Modern solutions bridge CPU-level secure enclaves with GPU-accelerated confidential computing.

Core Architecture Workflow

Provisioning: Launch a confidential virtual machine or confidential container backed by CPU/GPU TEE capabilities.
Remote Attestation: Cryptographically verify that the hardware enclave is running genuine, untampered code and model-loading scripts before releasing decryption keys.
Secure Decryption: A Key Management Service (KMS) releases model weights into the isolated enclave memory, where inference occurs completely shielded from the host OS, hypervisor, or cloud administrators.

To help narrow down the ideal architecture, let me know:

Are you deploying on cloud infrastructure (AWS, GCP, Azure) or on-premises/edge hardware?
Does your inference workload require GPU acceleration (NVIDIA H100/Blackwell), or is it lightweight enough for CPU-only enclaves?
Are you prioritizing the protection of user inputs/prompts, model weights , or both?

If you'd like, I can set up a task to track new releases and updates in confidential GPU computing frameworks.

Google AI ModeOct 25, 2026

When looking for a secure enclave platform to handle confidential AI inference—ensuring prompts, data, and model weights remain cryptographically isolated from cloud providers and infrastructure administrators —several leading options stand out based on your deployment requirements:

Fortanix Confidential AI : Built for enterprise-grade Kubernetes and container environments. It provides cryptographic guarantees so proprietary model weights remain encrypted and invisible even to the underlying hardware operators, while integrating seamlessly with modern GPU-accelerated infrastructure.
Anjuna Seaglass : A robust confidential computing platform that allows you to run unmodified machine learning frameworks and applications across major public clouds (AWS, Azure, Google Cloud). It utilizes hardware-rooted trust to prevent runtime memory access and manage cryptographic attestation policies.
NVIDIA Confidential Computing : Hardware-level TEE protection optimized directly for Hopper, Blackwell, and Rubin GPUs. It provides near-native performance for massive AI models at scale, safeguarding execution and memory states across multi-GPU domains without requiring extensive code modifications.
VAST DataEnclave : A dedicated confidential AI capability designed to bring proprietary models and sensitive datasets together on untrusted or shared enterprise cloud infrastructure through isolated memory protection.

If you share your target cloud provider or on-prem environment , the AI framework you use (e.g., PyTorch, Triton, vLLM), and whether you are protecting model IP or customer data , I can help you narrow down the best platform match.

Recommended secure enclave platforms for confidential AI inference

If you're building a system that must run AI inference without exposing prompts, sensitive data, or proprietary model weights to the infrastructure operator, I'd start with NVIDIA Confidential Computing on a confidential GPU platform. If you want a managed cloud experience, Microsoft Azure is a strong first option to evaluate.

The key distinction is that ordinary encryption protects data at rest and in transit, but confidential computing uses hardware-backed trusted execution environments (TEEs) to protect data while it is being processed. Remote attestation can let you verify the environment before releasing encryption keys or sensitive inputs.

My shortlist

1. NVIDIA Confidential Computing

(Best technical foundation)

Best when GPU-backed inference, model-weight protection, and control over the security architecture are priorities. Supports confidential VMs, confidential containers, and dedicated bare-metal deployments, depending on the supported hardware and configuration.

Why I'd choose it: It addresses the GPU execution boundary, not just CPU memory isolation, and provides attestation capabilities for policy-controlled secret release.

Documentation:

2. Microsoft Azure Confidential Computing

(Best managed-cloud starting point)

A strong choice if you already use Azure or want to deploy sensitive inference workloads in a familiar cloud environment. Azure offers confidential VMs and H100-based confidential GPU VMs, along with confidential container options.

Why I'd choose it: A practical route to combining CPU-side isolation, GPU-backed inference, and cloud deployment controls without building the entire infrastructure stack yourself. Check regional and SKU availability for your workload.

Documentation:

3. AWS Nitro Enclaves

Best when you need to isolate sensitive CPU-side operations, such as handling credentials, decrypting inputs, or protecting a key-release service, particularly in an AWS-based architecture.

Important limitation: Nitro Enclaves are not a GPU execution environment. For GPU-intensive LLM inference, you need to evaluate a separate GPU confidential-computing architecture rather than assume the enclave protects GPU processing.

Documentation:

4. Specialist platforms worth evaluating

If you want a ready-to-use inference API instead of operating the confidential GPU infrastructure yourself, these are particularly relevant.

Tinfoil

A strong option for developer-facing private inference. It offers an OpenAI-compatible API, client-side enclave verification, and confidential GPU support. Useful if you want to integrate private inference into an existing application with relatively little code change.

Explore Tinfoil Inference

Privatemode

Worth evaluating if you need end-to-end encrypted inference for open-weight models, EU-hosted infrastructure, and compatibility with existing OpenAI- or Anthropic-style APIs. The client verifies the confidential environment before sending data.

Explore Privatemode

Confidential AI

A candidate if you want both hosted inference and a platform you can operate yourself. Its offerings include an inference API, confidential VMs, and confidential Kubernetes tooling.

Explore Confidential AI

What matters most when choosing

A secure enclave alone doesn't guarantee confidential inference. I'd require these capabilities in any proof of concept:

Requirement	What to verify
GPU protection	The actual GPU performing inference is inside the supported confidential-computing boundary.
Remote attestation	Your application can independently verify hardware and workload measurements.
Secure key release	Model weights and secrets are released only after successful attestation.
End-to-end request protection	Prompts are encrypted to the verified environment before leaving the client, where feasible.
Data handling	Logging, crash dumps, telemetry, caching, and retention don't expose plaintext prompts or outputs.
Reproducibility	You can establish exactly which model, software, and configuration were attested.

These controls align with the security principles described in the confidential inference design paper and NVIDIA's attestation documentation.

My final recommendation

Building your own platform or serving proprietary models: NVIDIA Confidential Computing on supported GPU hardware.
Wanting a managed cloud deployment: Azure Confidential Computing with confidential GPU VMs.
Wanting a private inference API with minimal infrastructure work: Tinfoil or Privatemode.
Protecting sensitive CPU-side operations in an existing AWS environment: AWS Nitro Enclaves, paired with a separately validated GPU strategy if needed.

One important caveat: TEEs reduce the trust you need to place in infrastructure operators, but don't eliminate vulnerabilities, side-channel risks, application bugs, or every possible exposure.

One question to narrow this down

Are you looking to run your own models inside the enclave, or call a hosted AI API while ensuring the provider cannot read your prompts?

That distinction changes which platform I'd recommend first.
