About

We work with specific partners to host test URL's on various lists and have test pages hosted where they will be blocked.

This service was setup in response to the introduction of statutory guidance for schools in the UK about appropriate levels of filtering and monitoring of school internet connections. The UK Safer Internet Centre first published its filtering and monitoring definitions in 2016 to help both schools and providers understand what should be considered as ‘appropriate’.
