# Cloudflare DDoS Protection

Detect and mitigate distributed denial-of-service (DDoS) attacks automatically.

 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://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 

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 ](https://developers.cloudflare.com/ddos-protection/managed-rulesets/) 

###  Adaptive DDoS Protection 

Get increased protection against sophisticated DDoS attacks on layer 7 and layers 3/4.

[ Use Adaptive DDoS Protection ](https://developers.cloudflare.com/ddos-protection/managed-rulesets/adaptive-protection/) 

###  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 ](https://developers.cloudflare.com/ddos-protection/advanced-ddos-systems/overview/advanced-tcp-protection/) 

###  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 ](https://developers.cloudflare.com/ddos-protection/advanced-ddos-systems/overview/advanced-dns-protection/) 

###  Programmable Flow Protection 

Deploy custom eBPF packet logic across Cloudflare's network to inspect and mitigate DDoS attacks against UDP-based Layer 7 protocols.
