How we protect your data

Every layer of VoltageGPU is designed so we do not have technical means to access your data. Hardware enclaves, no prompt/output retention by design, EU hosting.

VoltageGPU vs. OpenAI

Regulatory Compliance

Built to meet the strictest regulatory frameworks for regulated industries.

EU Company

VOLTAGE EI · registered in France (SIREN 943 808 824). Subject to GDPR, not US CLOUD Act.

GDPR Art. 25

Data protection by design. Prompts and documents are processed inside the trust domain; account, billing and support data go through the sub-processors listed on this site.

Hardware Attestation

Intel TDX generates a cryptographic proof that code runs unmodified inside a sealed enclave.

Zero-Knowledge

The architecture is designed so we do not have technical means to read your data in plaintext · including during processing. CPU-fused AES keys encrypt all memory.

DPA Ready

Data Processing Agreement published in full at /legal/dpa. Countersigned copy on request.

No Retention By Design

Prompts and outputs are destroyed after each request. Nothing is logged or stored.

What is in place, what is in flight

Independent attestations are how regulated buyers verify a vendor's posture. Below is the authoritative status of VoltageGPU's certifications and the realistic timeline for the ones we have not yet earned. We tag every line so procurement and risk teams can rely on this page as a single source of truth.

We do not claim certifications we have not earned. VoltageGPU is not currently SOC 2, ISO 27001, ISO 42001 or HDS certified. Anywhere our marketing previously used a stronger word ("compliant", "certified"), it has been corrected to reflect architecture-readiness language. The dated targets above are commitments, not promises, they will move if scope or customer demand changes, and this page is the authoritative source.

How to report a security issue

We welcome coordinated disclosure from security researchers. The program below is the official policy referenced by our /.well-known/security.txt file (RFC 9116).

Where to report

Email security@voltagegpu.com with a clear reproduction. We acknowledge receipt within 3 business days and provide a triage update within 10 business days.

What is in scope

voltagegpu.com, app.voltagegpu.com, api.voltagegpu.com, docs.voltagegpu.com, our API surface, and the agent runtime.

Out of scope

DoS, social engineering, physical attacks, missing security headers without impact, self-XSS, and reports requiring already-compromised devices or networks.

Safe harbor

Research conducted under this policy in good faith is authorized. We will not pursue legal action against researchers who follow the rules, avoid privacy violations, and give us reasonable time to remediate before public disclosure (90 days standard).

Rewards

A paid bounty program is not currently offered. High-quality reports are eligible for public acknowledgment below and, at our discretion, service credits.

Languages

We accept reports in English and French.

Researchers who helped us

We recognize researchers who have responsibly disclosed valid issues. As a young company we have no acknowledgments yet, if you find something, you could be the first.

No public acknowledgments yet. Reports welcome at security@voltagegpu.com.

Chutes TEE Infrastructure

Our inference API runs on Chutes TEE nodes · models execute inside Intel TDX enclaves with zero data retention.

TDX Isolation

Each inference request runs inside a dedicated Intel TDX Trust Domain with AES-256 encrypted memory.

trust-domain GPU passthrough

GPU-to-CPU link is hardware-encrypted. Data in transit between processor and accelerator stays sealed.

Remote Attestation

Cryptographic proof that the enclave code has not been tampered with, verifiable before sending data.

LUKS Encryption

Filesystem encryption with keys released only after successful attestation. Data at rest is always encrypted.

Model Verification

Model weights are hash-verified on load to ensure the exact expected model is running inside the enclave.

Watchtower Monitoring

Continuous runtime integrity checks ensure the enclave remains sealed throughout the session.

Post-Quantum Ready

TLS 1.3 with post-quantum key exchange protects data in transit against future quantum attacks.

Hardware-Attested Output

Intel TD Quote evidence for the inference host is available on request and verifiable offline against Intel's public PKI.

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.
