The Annual Report 2021

About IWF

We detect, disrupt, remove, and prevent online child sexual abuse material using our expertise and resources as effectively as possible. The Internet Watch Foundation (IWF) is a technology-led, child protection organisation, making the internet a safer place for children and adults across the world. We’re a not-for-profit organisation working closely with police, governments and NGOs globally, who trust our work.

What we do


Child sexual abuse images and videos are just as much a weapon as a knife.

We actively search for this imagery and for the past 25 years, we’ve given people a safe place to report it to us, anonymously, now covering 50 countries.

We assess every report we receive. If it shows the sexual abuse of a child, we make sure the image or video is removed from the internet.

To do this effectively, we develop technology-for-good: We provide bespoke services, products and datasets to our industry Members to prevent the imagery from re-appearing and make it harder for offenders to find and share.

We care. Our work relies on compassionate and resilient staff members, who are highly trained and carefully looked after.

How you can support


We encourage others to play their part, whether it is reporting to us, funding us, or collaborating on the best technology and research.

The children in these pictures and videos are real. The suffering captured in this imagery and the knowledge that it could be shared can haunt a victim for life.

That’s why it’s our mission to remove this material for good. And to show every child there is someone out there who cares enough to help.
