Amazon EventBridge extends Customer Managed Key support to rule filter patterns and input transformers

Posted on: Sep 16, 2025

Amazon EventBridge now extends Amazon Key Management Service (KMS) customer managed key support to event bus rule filter patterns and input transformers. This capability enables you to use your own encryption keys to protect sensitive information in your event filtering and transformation logic to meet stringent security and compliance requirements while maintaining full control over your encryption keys.

Amazon EventBridge is a serverless event router that enables you to create scalable event-driven applications by routing events between your applications, third-party SaaS applications, and Amazon Web Services services. Filter patterns determine which events match your rules, while input transformers allow you to customize the event data before sending it to targets. By encrypting these components with customer managed keys, you can help meet your organization's compliance and governance requirements and use Amazon CloudTrail to audit and track encryption key usage.

This feature is available in Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD. Using this feature incurs no additional cost, but standard Amazon KMS pricing applies. To learn more, please refer to the Amazon EventBridge user guide.
