About VerifyFiltering

Independent verification for network filtering

Verify Filter is a free service built by CleanBrowsing Inc. in partnership with Friendly WiFi. It helps organizations independently verify that their networks comply with filtering guidelines set forth by regulatory bodies in their jurisdiction — or with their own internal acceptable use policies (AUP).

How it works

How Verify Filter Works

The scanner tests your network's DNS filtering against lists of domains known to fall within specific content categories, then gives you a clear pass/fail rating.

Choose a standard

Pick the compliance profile that applies to you — CIPA, UK Safer Internet, Friendly WiFi — or build a custom test from individual content categories.

Run the scan

From any device on the network you want to test, start the scan. Nothing is installed and no traffic is intercepted.

DNS lookups tested

The scanner checks how your network resolves domains known to fall within each selected content category.
