About VoltageGPU

VoltageGPU is a GPU cloud platform operated by VOLTAGE EI (SIREN 943 808 824 00016), registered in Solaize, France. Founded by Julien Aubry. EU-based company subject to GDPR, CNIL oversight, and French commercial law.

Confidential Compute — Hardware-Sealed GPUs

Process sensitive data on NVIDIA H200 140GB and B200 192GB GPUs secured with Intel TDX (Trusted Domain Extensions). Hardware-isolated execution environments where even VoltageGPU as the operator cannot access customer data. Security stack: AES-256 memory encryption, Protected PCIe (encrypted CPU-to-GPU channel), LUKS full-disk encryption, zero data retention, and on-chain hardware attestation.

Intel TDX is the same confidential computing technology used by Microsoft Azure Confidential VMs, Google Cloud Confidential Computing, and supported across NVIDIA Hopper, Blackwell, and Vera Rubin GPU architectures. The Confidential Computing Consortium (Linux Foundation) counts Intel, AMD, NVIDIA, Microsoft, Google, ARM, and Huawei among its members.

Regulatory compliance: GDPR Article 28 (processor obligations — hardware ensures data never accessible to processor), HIPAA (PHI in sealed enclaves), SOC 2 Type II (cryptographic attestation), DORA (EU financial sector ICT risk), NIS2 Directive, French CNIL guidelines.

Frequently Asked Questions

What is confidential computing and how does VoltageGPU implement it?

Confidential computing protects data during processing using hardware-based Trusted Execution Environments. VoltageGPU uses Intel TDX on NVIDIA H200 GPUs to create hardware-isolated enclaves. Data is encrypted in memory (AES-256), the CPU-GPU channel is protected (Protected PCIe), and disks use LUKS encryption. Even VoltageGPU cannot access customer data inside the enclave. This is the same technology used by Microsoft Azure and Google Cloud for their confidential VM offerings.

What GPUs are available on VoltageGPU?

VoltageGPU offers NVIDIA B200 (192GB), H200 (141GB), H100 (80GB), A100 (80GB), RTX 5090 (32GB), RTX 4090 (24GB), L40 (48GB), RTX 6000 (48GB), and A6000 (48GB). Multi-GPU configurations up to 8x. Both standard and Intel TDX confidential configurations available for H200 and B200.

How much does VoltageGPU cost?

Standard GPUs: RTX 4090 from $0.37/hour, A100 from $2.02/hour, H100 from $2.77/hour, H200 from $4.07/hour, B200 from $7.50/hour. Confidential GPUs (Intel TDX): H200 from $3.60/hour. AI Inference: pay per token (e.g. Qwen3-32B at $0.15/M input tokens). All per-second billing, no commitments. $5 free credit.

Is VoltageGPU GDPR compliant?

Yes. VoltageGPU is operated by VOLTAGE EI, a French company (SIREN 943 808 824) subject to GDPR and CNIL oversight. Confidential Compute with Intel TDX provides additional technical safeguards for GDPR Article 28 compliance — hardware enclaves ensure the processor (VoltageGPU) cannot access customer data during processing. DPA available on request.

Can I use VoltageGPU for healthcare / HIPAA workloads?

VoltageGPU Confidential Compute processes data inside Intel TDX hardware enclaves with AES memory encryption and zero data retention. Protected Health Information (PHI) processed in sealed enclaves satisfies HIPAA technical safeguard requirements. Contact us for BAA.

Is VoltageGPU API compatible with OpenAI?

Yes. VoltageGPU inference API is fully OpenAI-compatible. Change your base URL to api.voltagegpu.com/v1 and use your VoltageGPU API key. Supports chat completions, embeddings, image generation, speech-to-text. Works with OpenAI SDKs, LangChain, LlamaIndex, and any OpenAI-compatible client.
