About
Cloudflare provides unmetered and unlimited distributed denial-of-service (DDoS) protection at layers 3, 4, and 7 to all customers on all plans and services.
The protection is enabled by Cloudflare’s Autonomous DDoS Protection Edge, which automatically detects and mitigates DDoS attacks.
The Autonomous Edge includes multiple dynamic mitigation rules exposed as managed rulesets, which provide comprehensive protection against a variety of DDoS attacks across layers 3/4 and layer 7 of the OSI model.
Adaptive DDoS Protection also learns your unique traffic patterns and adapts to them to provide better protection against sophisticated DDoS attacks on layer 7 and layers 3/4. Your Internet properties can be secured from sophisticated TCP and DNS DDoS attacks using Advanced DDoS Protection that leverages stateful inspection and traffic profiling.
