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

For governed bare-metal GPU provisioning (i.e., infrastructure that pairs dedicated hardware with policy enforcement, quotas, audit logging, and tenant isolation) for secure AI training, look at two categories: (1) governance/orchestration layers that sit on top of bare metal, and (2) bare-metal providers with strong built-in compliance and isolation.

Governance/orchestration layers

• NorthWind adds a control plane specifically for this use case:

elastic, self-service provisioning of bare metal GPU servers with governance, visibility, and metering built in
. It also partners with VAST so that
NorthWind and VAST integrate governed compute orchestration and scalable data services, enabling NeoCloud providers and enterprises to transform raw infrastructure into consistent, production-ready AI platforms

• vCluster Platform provides per-tenant control-plane isolation on bare metal —

Each tenant gets their own API server, etcd, and RBAC — full cluster-admin without touching the host
— useful if you're building an internal "AI factory" with strict security boundaries. (vcluster.com)

Bare-metal providers with strong governance/compliance baked in

• CoreWeave offers

secure, single-tenant bare-metal clusters that enable isolated environments
, with HIPAA support and strong logging. (corvex.ai)

• FluidStack provides

single-tenant isolation as default deployment model; scales from 8 to 30,000 GPUs per cluster... comprehensive compliance (HIPAA, GDPR, ISO 27001, SOC 2 Type 2)
. (hostline.io)

• OpenMetal supports confidential computing:

both XL V4 and XXL V4 bare metal servers are equipped with TDX-capable CPUs, giving the ability to isolate memory and workloads at the hardware level
