Curated Digest: Referencing Custom AWS Secrets Manager Secrets in Amazon Bedrock AgentCore Identity
Coverage of aws-ml-blog
aws-ml-blog details a critical update for enterprise AI deployments, allowing organizations to integrate user-managed AWS Secrets Manager secrets with Amazon Bedrock AgentCore Identity for enhanced credential governance.
In a recent post, aws-ml-blog discusses a critical architectural update for enterprise generative AI deployments: the ability to reference your own AWS Secrets Manager secrets within Amazon Bedrock AgentCore Identity. This new capability directly addresses a fundamental security and governance requirement for organizations transitioning AI agents from experimental phases into robust production environments.
The operational landscape for AI agents is rapidly evolving. To be truly effective, these agents must interact dynamically with a wide array of external systems, including customer relationship management (CRM) platforms, communication tools like Slack, and version control repositories like GitHub. These interactions require secure, reliable runtime credential management. Hardcoding API keys or tokens is universally recognized as a severe security vulnerability. While Amazon Bedrock AgentCore Identity previously offered a mechanism to manage these secrets automatically, the default implementation presented limitations for mature enterprise environments. Specifically, it did not support the application of custom tags, sophisticated rotation policies, or the use of customer-managed Key Management Service (KMS) keys during the initial creation phase. This limitation created friction for security and compliance teams who require uniform governance standards across all cloud resources, including emerging AI workloads.
The aws-ml-blog publication details how AWS has resolved this friction by allowing developers to reference preconfigured, user-managed AWS Secrets Manager secrets directly within the AgentCore Identity framework. This is a substantial shift from relying solely on AWS-managed secrets. By utilizing customer-managed secrets, organizations can now directly extend their established secrets governance frameworks to encompass their AI agents. Security administrators can enforce custom KMS encryption to meet specific regulatory requirements, implement automated, time-based rotation policies to minimize the risk of credential compromise, and utilize custom tagging for granular resource tracking and precise identity-based access control. The post emphasizes that this feature is not merely a convenience, but a critical enabler for enterprise production deployments where strict compliance cannot be compromised. While the post focuses on the integration benefits, practitioners will also need to carefully consider the specific IAM configurations required to grant AgentCore Identity the appropriate access to these user-managed secrets, as well as how the token vault manages runtime token refresh cycles.
For cloud architects, security professionals, and AI developers tasked with building secure generative AI applications, mastering this integration is a mandatory step for maintaining robust credential governance. Implementing these practices ensures that AI agents operate within the exact same security boundaries as traditional enterprise applications.

Key Takeaways
- AI agents require secure, dynamic credential management to access external APIs without hardcoding sensitive information.
- Amazon Bedrock AgentCore Identity now supports referencing user-managed AWS Secrets Manager secrets, moving beyond default AWS-managed options.
- This update allows organizations to apply custom KMS encryption, automated rotation policies, and custom tags to AI agent credentials.
- The feature is critical for enterprise security teams needing to enforce strict compliance and governance over production AI workflows.
