Bedrock Guardrails operate outside agent code to evaluate every agent action and tool call in real time, blocking harmful content, sensitive data exposure, and prompt injections before reaching downstream systems. This provides consistent, centralized security enforcement for AI agents at scale.

Policy evaluations are logged for auditing and optimization, with policies authored in natural language or code. Guardrails are supported in key AWS regions and work with existing AgentCore deployments without new infrastructure, promoting secure enterprise AI agent operations.
