title: Build DNS security policies · Cloudflare Learning Paths
description: DNS security is an important, wide-reaching, and early action in
  the lifecycle of a request. Cloudflare operates one of the world's largest and
  fastest public DNS resolvers. Your users' public DNS requests will be resolved
  by that same resolution engine -- whether they are connecting from a network
  pointing its resolvers to Cloudflare or an endpoint running the WARP client.
