Robust security with fast performance
Get increased uptime and speed for your websites and other HTTP/s applications with Cloudflare’s automated, always-on, and unmetered DDoS protection.
With over 59 Tbps Tbps of network capacity and a global network that’s constantly learning from the approximately 25 million Internet properties on it, Cloudflare protects you against the largest and most sophisticated attacks.
Easily onboard your web applications within minutes from the dashboard or the API. Adding other Cloudflare security, performance, and reliability functionality is as easy as flipping a switch.
All Cloudflare plans offer unlimited and unmetered mitigation of DDoS attacks. Customers are not charged for attack traffic ever, period.
There’s no penalty for spikes due to attack traffic, requiring no chargeback by the customer.
With a simple change to your DNS settings, you can onboard your website to Cloudflare within minutes. Cloudflare’s globally distributed anycast network routes visitor requests to the nearest Cloudflare data center.
When Cloudflare’s edge data centers receive a request, they scan it to see if the visitor appears to be a threat, using criteria such as HTTP headers, user agent, query string, path, host, HTTP method, HTTP version, TLS cipher version, and request rate. We also look at HTTP response metrics such as error codes returned by customers’ origin servers.
Our global and local DoS mitigation systems work in concert to protect new and existing threats of any size or kind against your website.
Any resources that are already cached are served from Cloudflare’s data centers directly. Other client request traffic is sent to your origin server over Cloudflare’s high-performance network.
