BUILT FOR ANYTHING CONNECTED TO THE INTERNET

Cloudflare offers three DDoS protection solutions designed to protect everything on your cloud and on-premise networks.

Built for web applications

Our unmetered, always-on DDoS protection for your web assets (HTTP/HTTPs) is powered by the intelligence harnessed from Cloudflare’s always-learning global network. Cloudflare DDoS protection works in tandem with our cloud web application firewall (WAF), Bot Management, and other L3/4 security services to protect assets from cyber threats of all kinds.

Built for all other applications

Cloudflare Spectrum is a reverse proxy service that provides DDoS protection for any application (not just the web), such as FTP, SSH, VoIP, gaming, or any application running over a TCP/UDP protocol. Spectrum comes with built-in load balancing and traffic acceleration for L4 traffic.

Built for network infrastructure

Cloudflare Magic Transit provides BGP-based DDoS protection for network infrastructure, either in always-on or on-demand deployment modes. Data centers in all 200 cities across 100 countries announce customer subnets to ingest network traffic and mitigate threats close to the source of attack.

DDoS mitigation at Cloudflare scale.

Every server in every Cloudflare data center that spans 200 cities across 100 countries runs the full stack of DDoS mitigation services.

Cloudflare’s network capacity of 42 Tbps is well equipped to defend against the largest attacks.

Fast mitigation

Cloudflare centralized and decentralized mitigation systems work in concert to identify and mitigate most DDoS attacks in under 10 seconds (3 seconds on average). Preconfigured static rules are deployed in less than 1 second.

Cloudflare’s built-in analytics give you deeper insights into your traffic patterns, threats observed (and blocked), and much more right from the dashboard or via the Cloudflare GraphQL API. Cloudflare logs can also be integrated with third-party SIEMs.
