TL;DR: Enterprises shifting to self-hosted LLMs gain data sovereignty but also inherit a new AI infrastructure security gap, where vLLM, Ollama, and NVIDIA Triton can expose GPU memory, privileged runtime paths, and MCP-driven access, according to AccuKnox. The real control problem is no longer just model hosting, but governing the serving layer as a high-risk workload identity boundary.
NHIMG editorial — based on content published by AccuKnox: Securing Self-Hosted LLMs For Enterprises (vLLM, Ollama and NVIDIA Triton)
By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: How should security teams govern self-hosted LLM serving layers?
A: Treat the serving engine as a privileged workload identity, not a generic app container.
Q: Why do self-hosted LLMs increase data leakage risk?
A: They move inference, memory handling, and access control into the enterprise environment, where shared GPUs and privileged runtime paths can expose cached prompts, conversation fragments, or model artefacts.
Q: What breaks when AI serving engines run with excessive privileges?
A: Excess privilege lets a compromised inference service reach host resources, GPU drivers, local files, or internal networks that should be off limits.
Practitioner guidance
- Define the AI serving layer as a governed trust boundary Assign ownership for vLLM, Ollama, and Triton deployments, then document which data, APIs, and GPU resources they are allowed to touch.
- Restrict privileged GPU runtime paths Reduce container and host privileges needed for GPU driver interaction, and block unexpected process calls from the serving engine to local files or outbound destinations.
- Add GPU-aware monitoring and isolation Monitor memory, process, and driver interactions that standard CWPP tools miss, especially where multiple inference workloads share the same hardware.

Self-hosted AI creates a workload identity problem, not just a hosting problem. Once inference shifts in-house, the serving engine becomes a privileged non-human workload with permissions, trust assumptions, and lifecycle obligations. That changes how IAM and PAM teams should think about AI infrastructure, because the risk is no longer limited to model quality or container hardening. Practitioners need to treat the serving layer as an identity-governed asset with explicit ownership and revocation paths.
A question worth separating out:
Q: How should teams decide whether MCP access is safe enough to allow?
A: Teams should allow MCP access only when the agent or server can be bounded with explicit scopes, revocable credentials, and traceable client registration. If the integration depends on static secrets, shared keys, or opaque delegation, the access model is too durable for reliable governance and should be redesigned before production use.
