Today, AWS announces that Amazon Bedrock AgentCore now supports Bedrock Guardrails in policy, giving enterprises deeper safety and security controls as they scale AI agents in production. AgentCore policy is an authorization capability within Amazon Bedrock AgentCore that controls which actions AI agents are authorized to take. Guardrails give enterprises defenses against the top security and safety risks with AI agent workloads, including prompt injection attacks and sensitive data exposure.

Guardrails can evaluate the outputs of every authorized agent action and inputs of every call to a gateway target (tools, agents, and models) in real-time, helping detect and block prompt injection attacks, harmful content, and sensitive information exposure before they reach downstream systems. Guardrail results are evaluated in policy at the AgentCore gateway perimeter, outside the agent's code, ensuring consistent enforcement regardless of agent autonomy. All policy evaluations are logged via AgentCore observability for optimization and auditing purposes.

AgentCore policy works with existing AgentCore gateway deployments and requires no new infrastructure. Customers author policies through natural language or policy-as-code, with consumption-based pricing for policy evaluations.

Bedrock Guardrails are available in policy in US East (N. Virginia), Europe (London), Europe (Stockholm), Asia Pacific (Sydney), and Asia Pacific (Tokyo). To learn more, visit Amazon Bedrock AgentCore or explore the documentation.
