AWS Shield Advanced adopts Anti‑DDoS WAF rule group
🛡️ In June 2025 AWS introduced the AWS WAF Anti‑DDoS managed rule group to protect application‑layer (L7) traffic. Starting July 27, 2026, Shield Advanced will add this rule group to eligible web ACLs in Count mode and eventually replace Shield’s existing L7 automatic mitigation by January 1, 2027. The rollout includes a free evaluation period, configurable sensitivities, new Challenge actions, reduced WCU usage, and a dedicated dashboard and metrics for observability.
