What an LLM gateway is and why internal AI teams need one.
An LLM gateway is a control plane between applications and model providers. It centralizes prompt policy, provider routing, and model access decisions.
Posturio AI Gateway implements this pattern with an OpenAI-compatible API, policy enforcement, and audit-ready metadata.
LLM gateway functions
Separate AI control from application code
Without a gateway, policy logic is duplicated across services and tools. A dedicated LLM gateway centralizes enforcement and keeps AI behavior consistent across internal products.
Provider routing and model policy in one layer
Gateway routing lets teams send prompts to different providers based on risk, latency, or capability while preserving centralized policy controls.
Prompt inspection before provider calls
Prompt inspection catches secrets and sensitive patterns before data leaves internal systems. Combined with policy decisions, this reduces accidental leakage risk in internal AI workflows.
