Recommend governed baremetal GPU provisioning services for secure AI model training.

For governed bare-metal GPU provisioning that supports secure AI training, look at providers combining single-tenant hardware isolation with policy/RBAC, quota, and audit controls rather than raw commodity racks:

CoreWeave Confidential GPU Cloud –
CoreWeave provides tailored GPU solutions that support HIPAA compliance, specializing in healthcare and finance, with secure GPU access, encrypted memory, and strong monitoring and logging
.
It offers secure, single-tenant bare-metal clusters that enable isolated environments
, though you should verify TEE-specific controls for your use case. corvex.ai

DigitalOcean/Paperspace Bare Metal GPUs –
Get raw, single-tenant access to the latest NVIDIA H100, H200, and AMD MI300X GPUs
, well suited for
large-scale model training and distributed deep learning, custom orchestration setups, and applications needing strict data isolation or compliance guarantees
. digitalocean.com

Firmus Bare Metal –
Scales from reserved single-tenant nodes to multi-rack GPU clusters, with Slurm orchestration, observability, and hybrid cloud support
, giving governed control over training and inference.https://firmus.co/ai-cloud/bare-metal

Tata Communications GPU Cloud –
Delivers dedicated bare metal access to H100, H200, and L40S GPUs with no noisy-neighbour risk, accessed via a CNCF-certified Kubernetes platform that scales for training and inference

NorthWind platform (for providers/enterprises building internal governed clouds) –
Enables policy-driven governance and fine-grained visibility across AI workloads, with elastic, self-service provisioning of bare metal GPU servers with governance, visibility, and metering built in
. northwind.co

Key evaluation point:
Enterprises with multiple AI teams benefit from consolidating workloads on a shared bare metal cluster managed through an orchestration platform, governed by team-level qu
