AWS waf: Note: proactive engagement not available for Anti-DDoS AMR events

Service: waf · 2026-09-27 · Documentation low

File: waf/latest/developerguide/ddos-srt-proactive-engagement.md · Type: network

Summary

Adds a note clarifying that Shield Advanced proactive engagement is not triggered by events detected by the Anti-DDoS managed rule group (AMR), and directs users to set up alarms via AMR events/metrics or contact support.

Security assessment

Documents DDoS response behavior and how to get notified for AMR-detected events, which is security-adjacent guidance but does not address a specific vulnerability or incident.

Evidence

Proactive engagement is not available for events detected by the [Anti-DDoS managed rule group](https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-groups-anti-ddos.html) (AMR).

+###### Note
+
+Proactive engagement is not available for events detected by the [Anti-DDoS managed rule group](https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-groups-anti-ddos.html) (AMR). The Shield Advanced console gives you visibility into events for both Shield Advanced and Anti-DDoS AMR detections. Only an event that's detected by Shield Advanced can trigger the proactive engagement. To be notified for Anti-DDoS managed rule group events, set up alarms using events and metrics generated by the Anti-DDoS AMR. Contact support to engage with SRT if needed.
