AI Gateway is a policy enforcement point that sits in front of AI model endpoints and classifies, enforces, and routes every prompt before it reaches a model. The gateway classifies intent, complexity, and domain pre-inference (in roughly 38ms), applies customer-defined rules to block prompt injection, jailbreak, and data exfiltration attempts at the boundary, and routes requests to the model that matches the task's actual requirements rather than always sending traffic to a frontier model. It deploys inline in the request path without requiring application code changes or an SDK, and applies a single policy across multiple model providers (Claude, GPT, Llama, Granite, and open-weight endpoints). Every classification decision, the rule that fired, and the model that served the request are logged as a trace that can be forwarded to a SIEM for audit and evidence purposes, mapped to frameworks such as MITRE ATLAS, NIST AI RMF, ISO 42001, and the EU AI Act. The product is designed to work alongside other Starseer offerings: a model vulnerability scan that vets models before they can receive gateway traffic, and an AI detection and response product that consumes gateway traces for runtime investigation. Deployment options include SaaS, on-prem Kubernetes, and air-gapped environments.</description> <parameter name="summary">Gateway that classifies, blocks, and routes AI prompts to models before inference occurs
