DNSFilter offers the comprehensive ability to block domains based on content as well as any security threats that they pose. We also support SafeSearch functionality so that the appropriate content  is displayed in your search results. 

Content Categories

Content Categories are the fastest way to block large lists of undesirable domains. For example, blocking the "Social Networking" category will block Facebook, Twitter, and Instagram. When you block a particular category, it will be indicated by the button changing to the color Red, and showing a 🚫 icon.




Select from a wide variety of Filtering Categories to block or allow at your discretion. Unsure which domain falls into which category? Use our Domain Lookup Tool to confirm.

DNSFilter is able to offer Google, Bing, and YouTube SafeSearch options. DNSFilter simply offers the features already provided by these services, but makes it easy to enforce. SafeSearch cannot be overridden by the endusers if the SafeSearch options are enabled in your Filtering Policy (and you ensure that users are using our service for DNS).

SafeSearch Precedence

Enabling the SafeSearch options for a policy will override any blocking for the affected sites that would normally be blocked by the "Search Engines & Portals" category.

If you truly wish to ensure that Google, Bing, etc are blocked, you must disable the SafeSearch toggle(s) on the policy.

The same warning applies to YouTube (normally blocked by the "Entertainment" category)
