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.

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.
