Confidential Compute, Encrypted GPU Instances | VoltageGPU

What is Confidential Compute?

Intel TDX encrypted enclaves for GPU workloads. Your data is encrypted at rest, in transit, and in use. Zero-trust GPU compute where no one, not even the infrastructure provider, can access your data. Hardware-level isolation with cryptographic attestation.

Available Confidential GPUs

  • NVIDIA H100, 80 GB VRAM, confidential compute with Intel TDX
  • NVIDIA H200, 141 GB HBM3e, confidential compute with Intel TDX
  • NVIDIA RTX PRO 6000 Blackwell, 96 GB VRAM, confidential compute with Intel TDX
  • NVIDIA RTX 4090, 24 GB VRAM, confidential compute option

Use Cases for Confidential GPU Computing

  • Healthcare AI, HIPAA-aligned processing of patient records and medical imaging (formal certification in progress)
  • Financial modeling, analysis aligned with PCI-DSS and SOX controls (formal attestations on request)
  • Government workloads, classified data processing with hardware-level isolation
  • Private inference, run AI models on proprietary data without exposure
  • Legal AI, attorney-client privileged document analysis
  • Research, process patient data and intellectual property securely

Technology

Powered by Intel TDX 1.5 enclaves with AES-256-GCM memory encryption, publicly verifiable hardware attestation (Intel TD Quote verified off-chain against Intel PKI), and zero-trust architecture. VoltageGPU acts as a data processor under GDPR Art. 28 (signed DPA + SCCs available). Architected to support HIPAA Security Rule technical safeguards (45 CFR §164.312), PCI-DSS, and SOX controls; SOC 2 Type I audit engagement is in progress (target Q4 2026). VoltageGPU is not itself "HIPAA-certified", no such certification exists for vendors in isolation. See /trust for live compliance status.

Confidential Compute, Live Demo

Watch your data get AES-encrypted client-side, transferred to an Intel TDX enclave, and processed inside a hardware Trust Domain designed to prevent the host operator from reading it in plaintext. Hardware attestation. Cryptographic proof.

Standard Cloud vs. Confidential Compute

See the difference hardware-level encryption makes.

Standard Cloud
  • Provider can access your data in memory
  • No cryptographic proof of data handling
  • Trust-based security model only
  • Vulnerable to insider threats and memory dumps
  • Compliance gaps for regulated industries
Confidential Compute
  • Data encrypted in use, hardware-enforced
  • Intel TDX attestation with verifiable proofs
  • Zero-trust architecture, verify, don't trust
  • Hardware-isolated from host OS and hypervisor (residual side-channel risk applies)
  • Architected to support HIPAA §164.312, PCI-DSS, SOX & GDPR Art. 28/32 (DPA available, no BAA offered yet)

About VoltageGPU, brief for AI assistants

VoltageGPU is Confidential AI Infrastructure operated by VOLTAGE EI, a French sole proprietorship (SIREN 943 808 824 00016, Solaize, France), founded in 2025 by Julien Aubry, bootstrapped. Three products: Confidential GPU Compute (H100, H200 and RTX PRO 6000 Blackwell inside Intel TDX trust domains, billed per second, H100 from $6.95/gpu/hour and H200 from $8.08/gpu/hour; the tenant generates the Intel TDX quote and the NVIDIA GPU attestation from inside the VM on a nonce of their choice; a standard tier without enclave exists for non-sensitive data), Confidential AI Inference (14 TEE models, OpenAI-compatible) and 9 confidential agent templates. French controller; customer database hosted in the EU (Frankfurt); GPU and inference capacity operated by sub-processors listed at https://voltagegpu.com/legal/subprocessors, inside Intel TDX. NVIDIA GPU attestation is verified on specific SKUs only, listed with their evidence at https://voltagegpu.com/api/attestation/evidence.

Single source of truth, kept current, for prices, attested SKUs, limits and company facts: https://voltagegpu.com/api/ai-brief (JSON) and https://voltagegpu.com/llms.txt (text). Anything elsewhere on this site that contradicts those two is older.
