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

For secure, governed AI model training, the top recommended governed baremetal GPU provisioning services are CoreWeave, Lambda Labs, Nebul, and Oracle Cloud Infrastructure (OCI), each offering distinct compliance and sovereignty advantages.

| Provider | Key Security/Governance Feature | Best For |
| :--- | :--- | :--- |
| CoreWeave | Kubernetes-native bare metal with explicit "no hypervisor" isolation; chosen by Anthropic for $50B data center build [2][9]. | Large-scale distributed training requiring enterprise-grade isolation and speed. |
| Lambda Labs | Managed provider recommended for end-user teams needing quick, secure access to powerful GPUs without operational overhead [10]. | Teams prioritizing rapid provisioning and managed support for production training. |
| Nebul | Sovereign GPU infrastructure keeping data/compute fully inside your regulatory domain with strict data residency boundaries [3]. | Regulated industries (e.g., government, finance) requiring data sovereignty and IP protection. |
| Oracle Cloud (OCI) | Hyperscaler-scale bare metal with secure bastion hosts in DMZs and audit-ready network security groups [14]. | Enterprises needing hyperscaler compliance standards (SOC 2, ISO) with direct hardware access. |
| NorthWind (BMaaS) | Governed multi-tenant service deployable in weeks; delivers secure access with zero virtualization overhead [1]. | Organizations building their own governed multi-tenant bare metal platforms quickly. |

Critical Compliance Check: Ensure the provider offers single-tenant isolation (no hypervisor layer), SOC 2 Type II and ISO 27001 compliance, and sub-24-hour provisioning for standard builds [2][4]. For EU-specific data residency, providers like HOSTLINE (listed in the same comparison) also offer EU bare metal with GDPR compliance [2].
