Cloudflare is a technology company that offers security, performance, and reliability services for websites and online applications. Its main function is to act as a content delivery network (CDN) and reverse proxy between users and web servers, speeding up access to sites, protecting them from attacks, and improving their availability.
One of Cloudflare’s best-known services is DDoS (Distributed Denial of Service) protection, which helps keep sites up even under malicious overload attempts. It also provides a web application firewall (WAF), traffic optimization, load balancing, and performance analysis tools.
In addition, Cloudflare offers fast and secure DNS services, such as the popular 1.1.1.1, which improves privacy and browsing speed. Its global network of data centers allows content to be delivered from locations close to the user, reducing latency.
Cloudflare is used by millions of websites, from small blogs to large corporations, and plays a key role in the modern internet infrastructure, helping to make it faster, more secure, and more reliable.
