Building Safer RAG Applications on AKS with KAITO RAGEngine Guardrails
Challenge: Grounded Does Not Mean Safe
An enterprise RAG application retrieves an internal troubleshooting document containing an API credential, an employee email address, and a confidential project name. Retrieval improves the answer, but the model may also reproduce that information, potentially token by token through a streaming API.
Deterministic scanners can block or redact recognizable risks such as credentials, personal information, invisible Unicode, and prohibited terms. Semantic risks, including unsupported answers, toxicity, topic violations, and instruction overrides, require model-based evaluation rather than pattern matching alone.
Grounding gives the model relevant evidence for its response. Guardrails enforce what content the application is allowed to return.
KAITO RAGEngine currently provides centrally managed output guardrails for standard and streaming responses, with blocking, redaction, hot reload, metrics, and structured logs. This post configures and evaluates those controls on Azure Kubernetes Service (AKS), explains cross-chunk protection, and considers future semantic checks. RAGEngine does not currently scan user input or retrieved context or provide model-based scanners.
