Content Delivery System (CND) represents a set of geographically distributed servers designed to perform content caching to efficiently deliver it to users. Typically structured as a cluster, a CDN enables the rapid transfer of static data required for loading web pages, as well as other media elements, including JS files, HTML, images, and videos.

A properly configured CDN can protect websites against Distributed Denial-of-Service (DDOS) attacks, reducing their impact on project operations. By distributing traffic across multiple servers, a CDN can absorb and disperse the high volume of requests generated by a DDOS attack, minimizing the risk of overloading the main server.

Moreover, many CDNs offer additional security features such as malicious traffic filtering, blocking suspicious IP addresses, and continuous monitoring of activity to detect and prevent other types of cyber attacks.

CDNs are compatible with a wide range of platforms and web technologies, allowing for easy integration into various infrastructures or panels. Many platforms provide advanced analytics and reporting tools, enabling performance and security monitoring, thus providing useful data for continuous site optimization.

Some of the most popular CDN platforms include CloudFlare, Fastly, Quic, Amazon CloudFront, and Google Cloud CDN.
