Keep on top of dangerous inappropriate content

The IWF (Internet Watch Foundation) is a not-for-profit organisation working to minimise the availability of online sexual abuse content by identifying images and videos of children through public reports and internal teams. The IWF list contains specific web pages, or URLs. Every URL on the list depicts indecent images of children, advertisements for or links to such content, on a publicly available website. The list typically contains 500 – 800 URLs at any one time and is updated twice a day to ensure all entries are still live.

Lightspeed Systems® is a proud Member of the IWF and have worked with them for over 10 years to give our customers the best protection against these harmful sites.
