Policy Secures Bedrock AgentCore Agents
๐กSecure Bedrock agents with runtime policy enforcement & identity controls
โก 30-Second TL;DR
What Changed
Policy layer operates independently of agent reasoning for enforcement
Why It Matters
Enhances security for AI agents by ensuring only authorized data/tools access, reducing risks in enterprise deployments of Bedrock agents.
What To Do Next
Convert business rules to Cedar policies in Bedrock AgentCore and deploy via Gateway.
Key Points
- โขPolicy layer operates independently of agent reasoning for enforcement
- โขGenerates Cedar policies from natural language business rules
- โขEnforces identity-aware controls via AgentCore Gateway at runtime

๐ Enhanced Key Takeaways
- โขPolicy integrates with AgentCore Gateway to intercept every tool call in real-time, processing thousands of requests per second with millisecond latency.
- โขAgentCore Evaluations provides 13 built-in evaluators for metrics like correctness, helpfulness, safety, and tool selection, plus custom model-based scoring with CloudWatch dashboards.
- โขAgentCore Memory now features episodic memory for agents to learn from experiences, while AgentCore Runtime supports bidirectional streaming for voice agents handling interruptions.
- โขPolicy reached general availability on March 9, 2026, after preview availability in all AWS Regions where AgentCore operates.
๐ ๏ธ Technical Deep Dive
- โขPolicy enforcement intercepts all agent-tool traffic via AgentCore Gateway, evaluating requests against policies stored in a policy engine before access.
- โขSupports fine-grained access controls based on user identity, tool input parameters, and conditions; integrates with VPC security groups and AWS security infrastructure.
- โขNatural language authoring translates English prompts to validated Cedar policies; provides CloudWatch monitoring for policy evaluations and audit logging of decisions.
- โขOperates deterministically outside agent code, ensuring consistent enforcement regardless of agent implementation.
