One HIPAA-compliant gateway routing all LLM traffic with BAA coverage, audit logging, key management, and cost controls enforced automatically.
LLM Gateway sits between applications and model providers (Anthropic, OpenAI, Bedrock-hosted models) under a single BAA, enforcing audit logging of requests and responses, encrypted log storage with export, scoped key management and model-access governance, budget limits with alerts or hard stops, plus protocol translation and capacity management.
It governs production AI features and internal workflows touching PHI, giving regulated teams one audited control point for every model call.
