How Cloudflare works?

Many site providers offer direct Cloudflare integration via their web hosting Cpanel, but you may also join up directly at Click Add Site, then follow the instructions to change your domain’s name servers. That’s it, you’re now utilizing Cloudflare. Technically, Cloudflare functions as a reverse proxy, which means that all traffic is routed through Cloudflare servers located in over 200 cities globally.

Cloudflare is the first service to combine security with speed. Cloudflare servers, known as “Edge” servers by the company, cache the contents of the webpage and serve as a CDN. Because traffic must pass through the Edge server before reaching the original web server, Cloudflare can block malicious bots, protect against DDoS, and block traffic based on firewall rules.
