# Contents Delivery Network (CDN)

A CDN (Content Delivery Network) is a special network designed for delivering online content while providing improved security and performance. 

Implementing CDN to HollaEx Core would improve the global latency, enhance security, and anonymize real IP.

HollaEx highly recommends using [**Cloudflare CDN for HollaEx**](/advanced/contents-delivery-network/cloudflare-cdn-for-hollaex.md)**.** Cloudflare provides **advanced security and global performance** **for free.** Using Cloudflare is highly beneficial if you are dealing with a global audience or want to protect against **DDoS** or **cyber attacks**, including setting up an **IP whitelist** or implementing a **geolocation lock** for your exchange. The compatibility of Cloudflare with HollaEx is fully verified by the HollaEx team.

Alternatively, you can consider using other public CDNs. Here are some of the common public CDN services you could implement with HollaEx easily. This list will be constantly updated.
