Private AI Inference — HIPAA & GDPR Compliant Confidential Compute on Intel TDX

What is Confidential Compute?

Confidential computing protects data during processing using hardware-based Trusted Execution Environments (TEEs). VoltageGPU provides NVIDIA H200 140GB GPUs secured with Intel TDX (Trusted Domain Extensions). Your workload runs as an attested container inside a hardware-isolated Trust Domain — a CPU-sealed virtual machine that even the host operator, hypervisor, and VoltageGPU cannot access. This is the same TDX technology used by Microsoft Azure Confidential Computing and Google Cloud Confidential VMs, with the container model keeping deploys to under 60 seconds rather than minutes.

Security Architecture

  • Intel TDX (Trusted Domain Extensions) — Hardware-isolated VMs verified by CPU microcode. Even the hypervisor and host OS cannot access enclave memory.
  • AES-256 Memory Encryption — All RAM encrypted at hardware level using AES-256-XTS. Physical memory dumps reveal nothing.
  • Protected PCIe — CPU-to-GPU communication encrypted in transit. Bus sniffing attacks neutralized.
  • LUKS Disk Encryption — Full block-level disk encryption. Data at rest always sealed.
  • Zero Data Retention — Data cryptographically erased when enclave terminates. No logs, no traces.
  • On-Chain Attestation — Enclave firmware and state hashes verified cryptographically and recorded on a public ledger.

Hardware Specifications

  • NVIDIA H200 — 141 GB HBM3e, Confidential Computing mode, Protected PCIe
  • NVIDIA B200 — 192 GB HBM3e, next-generation Blackwell architecture
  • Intel TDX on 4th/5th Gen Xeon Scalable processors
  • Per-second billing, no minimum commitment

Compliance and Regulatory Frameworks

Confidential computing with Intel TDX addresses requirements across multiple regulatory frameworks:

  • GDPR Article 28 — Processor obligations for data protection. Hardware enclaves ensure data is never accessible to the processor (VoltageGPU).
  • HIPAA — Protected Health Information (PHI) processed inside sealed enclaves satisfies technical safeguard requirements.
  • SOC 2 Type I (in progress) — Audit initiated, expected Q3 2026. Hardware attestation provides cryptographic proof of security controls.
  • DORA (Digital Operational Resilience Act) — EU financial sector ICT risk management compliance.
  • NIS2 Directive — EU cybersecurity requirements for essential and important entities.
  • French CNIL guidelines — Data processing with technical measures preventing processor access.

Industry Adoption of Confidential Computing

Confidential computing is adopted by leading cloud providers and enterprises:

  • Microsoft Azure Confidential Computing — Intel TDX and AMD SEV-SNP based VMs
  • Google Cloud Confidential VMs — Intel TDX support on N2D and C3 instances
  • NVIDIA Confidential Computing — Hopper, Blackwell, and Vera Rubin GPU architectures
  • Confidential Computing Consortium (Linux Foundation) — Members include Intel, AMD, NVIDIA, Microsoft, Google, ARM, Huawei
  • Fortanix — Healthcare clinical data processing (Xeureka partnership)
  • Anjuna Security — Public sector secured LLM deployment

Use Cases

  • Law firms — Analyze contracts, NDAs, and privileged documents without exposing client data to third parties. Satisfies bar association data protection requirements.
  • Financial services — Process quarterly reports, audit data, and transaction records. DORA and MiFID II compliant processing.
  • Healthcare — Analyze patient records and clinical data inside sealed enclaves. HIPAA technical safeguard compliance.
  • Government and defense — Process classified or sensitive documents with hardware-verified isolation.
  • Compliance teams — Run AI on regulated data with audit-ready hardware attestation for GDPR Art. 28, DORA, NIS2, and CNIL requirements.

New to the technology? Read our plain-language guide to confidential computing — what hardware enclaves are, how Intel TDX works, and why it matters for AI.

How it works

01

Upload your workload

Push your model, container, or notebook to a sealed GPU pod.

02

Sealed in Intel TDX

Your workload launches inside a hardware enclave — encrypted memory, protected PCIe.

03

Run your compute

Full GPU access, SSH, web terminal. Data never leaves the enclave.

04

Verify attestation

Cryptographic proof your enclave is genuine — verifiable before and during execution.

Security Architecture

Intel TDX Enclaves

Hardware-level isolation — the hypervisor and host OS cannot access enclave memory.

AES Memory Encryption

RAM is cryptographically isolated from the hypervisor and host operating system.

Protected PCIe

CPU-to-GPU channel encrypted — data cannot be intercepted at the bus level.

LUKS Disk Encryption

Filesystem encryption with keys released only after successful attestation.

Zero Retention

Memory wiped after every session. No prompts, outputs, or logs are stored.

On-chain Attestation

Cryptographic proof the enclave is authentic before your code runs.

Compliance & Certifications

We meet the strictest regulatory requirements.

Security for Sensitive Data — Full Technical Details

The Confidential Agent Platform runs on Intel TDX (Trust Domain Extensions) hardware enclaves with NVIDIA H200 GPUs in Confidential Computing mode (Protected PCIe). The security stack: (1) Intel TDX encrypts RAM with hardware-fused CPU keys — the hypervisor is OUTSIDE the trust boundary and physically cannot access TD memory. (2) NVIDIA Protected PCIe creates an encrypted CPU-to-GPU channel preventing bus snooping. (3) LUKS encrypted filesystem — decryption key released ONLY after successful remote attestation. (4) Remote attestation: Intel TD Quote (signed by CPU-fused private key) verified against Intel public keys plus NVIDIA GPU attestation plus proof of VRAM work. Only PERFECT measurement matches pass. (5) Post-quantum end-to-end encryption for prompts and responses. (6) Model verification cryptographically proves every output token came from the declared TEE model, defeating model substitution attacks. (7) Continuous monitoring with random integrity challenges and immediate node removal on failure. Real-time public attestation reports available. This is not software security — it is silicon-level isolation verified by Intel and NVIDIA hardware attestation. EU company (France), GDPR Art. 25, Intel TDX hardware attestation.

Not Limited to 8 Templates — Connect Your Own Agent

The 8 templates are starting points. Any OpenAI-compatible agent works: OpenClaw (247K+ GitHub stars), CrewAI (50K+), LangChain (100K+), or any custom agent. Change one line (base_url) and every LLM call runs inside a TDX enclave. The platform is an API, not a closed system.

Model Quality — Not Just LLM Output

Three model tiers: Starter uses Qwen3-32B-TEE (32B params, 40K ctx), Pro uses Qwen3.5-397B-TEE (397B MoE, 256K ctx — can ingest entire contracts), Enterprise uses DeepSeek-R1-TEE (reasoning model with chain-of-thought for CFA-grade analysis). The key differentiator is the TOOLS, not just the model. Tools are deterministic server-side code: the clause checklist runs exact IACCM/ABA rules, the risk score uses a fixed formula (critical x25, high x15, medium x8), the market benchmark compares against 12 real 2024-2026 deal data points. The LLM orchestrates which tools to use, but the tools produce exact, verifiable results. Model verification (cllmv) cryptographically proves every output token came from the declared TEE model.

Performance — No TDX Overhead in Practice

Intel TDX adds 3-7% overhead theoretically. In practice, VoltageGPU uses 8x NVIDIA H200 140GB (top-tier GPU) which more than compensates. Analysis completes in approximately 6 seconds. The warm-tdx system keeps enclaves pre-heated — zero cold start for subscribers. Per-second billing means you only pay for actual compute time.

Competitive Comparison
