A CDN distributes static and cacheable content to nodes around the world, so user requests are answered nearby and the origin therefore does not see most of the traffic; a WAF performs rule matching on requests at the nodes, and can allow, challenge, rate-limit or block based on conditions such as path, method, request headers, User-Agent and IP reputation.

VerifiedCDN accelerates access by deploying a large number of edge nodes (PoPs) globally or nationwide and caching content at the node closest to the user.72% similarUnverifiedCDNs are inherently suited to absorbing traffic surges because content is already distributed and cached at edge nodes, without relying on a single origin server to handle all requests.70% similarUnverifiedCDNs reduce physical network transmission latency by deploying edge nodes globally to cache static assets on servers closest to users.69% similarUnverifiedAt the load balancer layer, only CDN IP ranges should be accepted, ideally requiring mutual TLS between the edge and the origin (which Cloudflare calls Authenticated Origin Pulls), and per-client rate limits, connection limits, client body/header timeouts and maximum body size should be set. The key lines return a cheap 404 for sensitive patterns, such as `location ~ /\.(?!well-known) { return 404; }` and `location ~* \.(env|ya?ml|sql|bak|old|log)$ { return 404; }`.68% similar
