A guide to DNS filtering: Secure your network at the source
Modernize your defense with intelligence from 5.7 trillion daily queries to block threats before they reach your network.
In the 2026 threat landscape, reactive security is not enough. As teams use more AI tools and decentralized workflows, legacy hardware and local filtering create gaps that ransomware and phishing are designed to exploit.
To stay fast, security must be proactive, lightweight, and global. This brief explains how Cloudflare DNS filtering acts as the first layer of a modern security stack, providing the control you need for a distributed team.
Download this brief to learn how to:
- Close the visibility gap: Use real-time threat intelligence from one of the world’s largest DNS resolvers to see unmanaged AI and application usage
- Automate threat prevention: Move beyond manual blocklists to automatically stop phishing and C2 callbacks across 300+ locations
- Scale without complexity: Use a cloud-native approach to deploy acceptable use policies in minutes via APIs or Terraform
- Build your SASE foundation: See how DNS filtering provides the starting point for a full SASE transformation on a single connectivity cloud
