This feature allows the AWS WAF JavaScript SDK to be added without modifying application code or deployment pipelines. The SDK generates client-side signals used by managed rule groups for bot control, account takeover prevention (ATP), and account creation fraud prevention (ACFP).

Prior to this, embedding the SDK script tag per page was manual and error-prone. Automatic SDK integration reduces misconfiguration risks and operational overhead, is available without additional cost, and can be enabled via console or APIs on web ACLs protecting CloudFront distributions containing specific managed rule groups.
