IWF URL List Recipients

The Internet Watch Foundation (IWF) provides a dynamic list of individual web pages with child sexual abuse content to its members, companies within their group and Licensees that have the ability to filter and block access to such content.

The following Member companies and Licensees have voluntarily committed to block access to child sexual abuse web pages thereby protecting consumers of their services from being inadvertently exposed to such content. The list is supplied to IWF Members including internet service providers, mobile operators, search and content providers and filtering companies as well as to Licensees. The companies below may deploy the list in different ways across some or all of their services and technology platforms.

There is an agreed self-certification process for verifying that those providers listed below as blocking URLs included in the list are testing their systems for doing so. 

If you have any queries regarding your provider please contact them directly. For more information on the blocking initiative see here
