Case Study: AdGuard cuts bandwidth costs and delivers up to 4x faster performance with Cloudflare

AdGuard drops bandwidth costs while providing a faster service by using Cloudflare

AdGuard, an ad‑blocking solutions provider, needed to deliver fast, reliable updates and site performance to a global user base. As the company expanded, users far from its servers experienced slow or unavailable service, frequent filter updates drove high bandwidth costs, and occasional DDoS attacks threatened availability.

AdGuard deployed Cloudflare’s CDN and security services to cache site content and ad‑filter updates from data centers in 200+ cities. Serving 150+ TB through Cloudflare cut bandwidth bills, halved load times in Europe and produced a 4x speed improvement in the U.S., boosted search rankings and leads, and Cloudflare’s DDoS protection blocked every attack encountered.
