Available on all plans Cloudflare automatically detects and mitigates [distributed denial-of-service (DDoS) attacks](https://www.cloudflare.com/learning/ddos/what-is-a-ddos-attack/) via our autonomous DDoS systems. These systems include multiple dynamic mitigation rules exposed as [DDoS attack protection managed rulesets](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/managed-rulesets/). You can customize the mitigation rules included in these rulesets to optimize and tailor the protection to your needs. --- ## Features [Managed rulesets](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/managed-rulesets/) Protect against a variety of DDoS attacks across layers 3/4 (network layer) and layer 7 (application layer) of the OSI model. Use Managed rulesets [Adaptive DDoS Protection](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/managed-rulesets/adaptive-protection/) Get increased protection against sophisticated DDoS attacks on layer 7 and layers 3/4. Use Adaptive DDoS Protection [Advanced TCP Protection](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/advanced-ddos-systems/overview/advanced-tcp-protection/) Detect and mitigate sophisticated out-of-state TCP attacks such as randomized and spoofed ACK floods, or SYN and SYN-ACK floods. Use Advanced TCP Protection [Advanced DNS Protection](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/advanced-ddos-systems/overview/advanced-dns-protection/) Protect against DNS-based DDoS attacks, specifically sophisticated and fully randomized DNS attacks such as random prefix attacks. Use Advanced DNS Protection [Programmable Flow Protection](https://e8aee267.previews.developers.cloudflare.com/ddos-protection/advanced-ddos-systems/overview/programmable-flow-protection/) Deploy custom eBPF packet logic across Cloudflare's network to inspect and mitigate DDoS attacks against UDP-based Layer 7 protocols.
