Unmetered DDoS Protection
Cloudflare DDoS protection secures websites and applications while ensuring the performance of legitimate traffic is not compromised.

CDN
Our 330 data centers located across the globe provide visitors with location-based access to your website, while removing latency and improving performance.
Web Application Firewall (WAF)
Cloudflare Web Application Firewall's intuitive dashboard enables users to build powerful rules through easy clicks and also provides Terraform integration. Every request to the WAF is inspected against the rule engine and the threat intelligence curated from protecting millions of websites. Suspicious requests can be blocked, challenged, or logged per the needs of the user while legitimate requests are routed to the destination, agnostic of whether it lives on-premises or in the cloud.
Lossless Image Optimization
Polish applies "lossless" or optional "lossy" image optimization to reduce your image sizes by 35% on average.
Accelerated Mobile Pages (AMP)
Mirage automatically optimizes image loading through virtualized and lazyloaded images. It detects the browser type of a visitor and optimizes performance for the particular device, improving the performance of images on a mobile connection.
