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 designed so that the host operator, hypervisor, and VoltageGPU do not have technical means to read enclave memory in plaintext. 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. No security control eliminates all residual risk (e.g., side-channel attacks on shared hardware) — TDX raises the cost of unauthorized access rather than guaranteeing absolute protection.

Security Architecture

  • Intel TDX (Trusted Domain Extensions) — Hardware-isolated VMs verified by CPU microcode. The architecture is designed so that the hypervisor and host OS do not have technical means to read enclave memory in plaintext.
  • AES-256-XTS Memory Encryption — RAM encrypted at hardware level using AES-256-XTS with keys fused into the CPU. Physical memory dumps yield ciphertext rather than plaintext.
  • Protected PCIe — CPU-to-GPU communication encrypted in transit, mitigating bus-sniffing attacks under the TDX threat model.
  • LUKS Disk Encryption — Full block-level disk encryption for data at rest.
  • No prompt/output retention by design — Enclave memory and disk state are destroyed when the pod terminates. Security and billing logs are retained per the schedule at /legal/security.
  • Publicly verifiable attestation — Intel TD Quote and NVIDIA GPU attestation reports are signed by CPU/GPU-fused private keys and verified off-chain against Intel and NVIDIA public PKIs (DCAP). No blockchain is required; no customer data is published.

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 is architected to support requirements across multiple regulatory frameworks. Final compliance assessment depends on customer configuration and use. See /trust for live status and disclaimers.

  • GDPR Article 28 (in place) — VoltageGPU acts as processor; signed DPA + SCCs available on request. The TDX architecture is designed so that the processor does not have technical means to read customer data in plaintext, complementing contractual safeguards.
  • HIPAA (architected to support) — Designed to support 45 CFR §164.312 technical safeguards for PHI processing. BAA available on request. VoltageGPU is not itself "HIPAA-certified" — no such certification exists for vendors in isolation; the covered entity remains responsible for end-to-end HIPAA compliance.
  • SOC 2 Type I (audit firm selection in progress, target Q4 2026) — NOT YET HELD. Hardware attestation is intended to support evidence of security controls.
  • ISO 27001 / ISO 42001 (target Q1 2027 / 2027 in scope) — NOT YET HELD. Roadmap published at /trust.
  • DORA Article 30 — Contractual provisions available for ICT third-party service contracts (NIS2 and DORA obligate operators/financial entities, not vendors).
  • NIS2 Article 21 — Aligned with risk-management measures expected from ICT supply-chain providers.
  • EU AI Act (Aug 2026) — Designed to support provider/deployer obligations; attestation evidence is intended to support Art. 15 cybersecurity documentation for high-risk systems.
  • French CNIL — Aligned with CNIL guidance on confidential AI processing. CNIL does not certify vendors.

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 inside hardware enclaves, architected to support professional-secrecy obligations. Final compliance is the firm's responsibility under applicable bar rules.
  • Financial services — Process quarterly reports, audit data, and transaction records. Architected to support DORA Art. 30 and MiFID II ICT requirements (contractual provisions available).
  • Healthcare — Analyze patient records and clinical data inside sealed enclaves, designed to support HIPAA technical safeguards. BAA required for PHI processing.
  • Government and defense — Process sensitive documents with hardware-verified isolation and publicly verifiable attestation.
  • Compliance teams — Run AI on regulated data with attestation evidence intended to support GDPR Art. 28, DORA Art. 30, NIS2 Art. 21, and CNIL guidance.

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 9 Templates — Connect Your Own Agent

The 9 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: Free uses Qwen3-32B-TEE (32B params, 40K ctx), Plus / Team Starter / Pro use 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

Confidential Compute: VoltageGPU TDX H200 $4.93/hr vs Azure Confidential H100 $14/hr. Legal AI: VoltageGPU $349/month vs Harvey AI $1,200/seat/month. Confidential GPU Compute: H100 from $3.75/hr, H200 from $4.93/hr, B200 from $7.50/hr.
