The filtering reality

Configuration doesn’t always reflect reality.

Filtering policies may appear correctly configured, but exceptions, categorisation errors, device settings and network changes can affect what users can actually access.

Filter Sentinel tests filtering from within your education network, providing clear evidence of how those controls behave in practice.
