What is DNS Filtering?

DNS Filtering is a content filtering service that relies on the Domain Name System (DNS) to block, or allow, content on a specific network. DNS offers users, and organizations, the ability to apply access rules across all devices independent of the OS or browser type. It is not tied to a specific technology, and it's at the core of how the web works.

Platform and browser agnostic;

NXDOMAIN and Null response on bad domain queries;

Performant and secure DNS resolver;

How CleanBrowsing Works


CleanBrowsing is a DNS-based content filtering (DNS Filter) service that allows you to create a safe browsing experience on your network.


Technically, we are a DNS resolver. DNS resolvers are a core piece of how the internet works. Every device connecting to the internet makes use of DNS.


Leveraging this technology allows us to provide a installation free cloud service that can filter requests made to the internet from your device or network.


With CleanBrowsing you have the ability to filter things like pornography, obscene and malicious content, and a slew of other online categories that might be deemed inappropriate for your network. 


We offer free and paid filtering options, where the free service is fixed and the paid services are customizable. 

The CleanBrowsing is built on an anycast network with over 50+ datacenters around the world. It leverages a proprietary machine learning platform for discovery and classification of new domains. As a DNS resolver, it is limited to filtering Fully Qualified Domain Names (FQDN)


Key highlights of our architecture include:


  1. Redundancy through clustered environments
  2. Redundancy through unique network pairs
  3. Availability through a global anycast network (+ 50 POP)
