Voltagegpu Reviews 

We needed an H100 with confidential computing actually switched on (Intel TDX + GPU CC mode) to test hardware attestation. The large clouds either didn't offer it on demand or wanted quota requests and long waits. VoltageGPU had one running within minutes, and nvidia-smi conf-compute showed CC on from the start. NVIDIA's remote attestation service verified the GPU on the first try.
Pricing was clear at $6.95/hr, SSH access was simple, and the machine held up through runs of six hours or more without problems. For a small team doing security work, it was the only practical option we found.
One tip for others: copy your results off the pod as you go. One of our pods was stopped while it sat idle and we lost that run's output, so we now sync to a local machine every 10 minutes. Clearer warnings before an idle pod is stopped would make it even better.
Recommended for anyone who needs real confidential-computing GPUs without an enterprise contract.

Great in depth support, reliable operations, and no data inspection guaranteed, and affordable

Great! Fast personal responses from the owner Julien.

I've tested a lot of use cases using VoltageGPU, and it worked seamlessly. It helped me a lot when I needed access to GPUs.

I ran Confidential VMs on VoltageGPU, RTX PRO 6000 and H100. When ten of my launches failed overnight, Julien found it before I did, told me it was their provider's change, not my side, and none of the attempts were charged. He credited an hour of RTX PRO 6000 to my balance and added launch-refusal alerts so it won't sit unnoticed again. When I asked whether their dashboard or API exposes the VM's SSH host key, he tested it on a live h100-small and told me straight: no, it doesn't, and the TDX quote proves a genuine VM on their image, not your VM. That's the kind of honesty you don't get from most providers. Five stars.

We used VoltageGPU’s H100 Confidential VM to run energy-measurement and attestation experiments on GPUs with confidential computing.

What worked well:

A genuine Intel TDX VM with NVIDIA confidential computing on the H100. We verified the TDX quote and the GPU attestation ourselves, and NVML power telemetry works inside the enclave.
Hourly pricing and EU location, which suit short, repeatable experiments.
Support stands out. When we hit a vLLM failure under confidential computing, Julien wrote his own CUDA probe, ran a non-confidential control and helped pin down the root cause. That is rare at any provider.
What could be better:

Powering off a VM doesn’t stop billing; you need to release it in the dashboard. Worth making that more obvious.
Host security patch level is something to check yourself if your policy requires the latest Intel TCB baseline. VoltageGPU was transparent about it and raised it with their provider.
Overall: a serious option for confidential GPU work, run by people who care about getting it right.

Very good neocloud, positive interactions with the host and good access to TDX and Nvidia CC.
