Internet Watch Foundation (IWF)

Working together to stop child sexual abuse online


The Internet Watch Foundation (IWF) is a non-profit child protection organisation working globally to stop the spread of online child sexual abuse imagery. Every day, our specialist analysts search for and respond to reports of images and videos showing the sexual abuse of children, working with the tech industry, law enforcement and governments worldwide to have criminal content removed and blocked. While we use advanced technology to help locate this material, every image is assessed by trained human experts, supported by gold-standard welfare and wellbeing care. Our work exists to stop the ongoing harm caused when abuse imagery is viewed or shared, and to help create a safer internet for children. 


How Your Support Helps

Choosing to fundraise for the Internet Watch Foundation is a way to take practical action against a growing online harm. Funds raised support specialist teams who work every day to disrupt the sharing of child sexual abuse imagery, strengthen protections across the internet, and support those doing this difficult workWhilst the harm our criminal imagery-viewing staff are exposed to in carrying out this work pales in comparison with the mental damage done to the children in that material, each member of staff who views images or videos of child sexual abuse is confronting that trauma on behalf of the rest of us in society, who care deeply about protection of children in an increasingly digitalised world.   By fundraising for the IWF, supporters help turn determination into measurable change and play a direct role in keeping children safer online. 

£20 could help add webpages to the IWF’s blocking list, preventing children and adults from accidentally stumbling across child sexual abuse imagery online. 

£100 could support the issuing of multiple takedown notices to companies hosting criminal content, helping to prevent further sharing and harm. 

£250 could help provide counselling sessions for Hotline analysts as part of the IWF’s duty of care and wellbeing programme. 

£1,000 could help fund essential hardware and technology that analysts rely on to remove images of child sexual abuse from the internet. 

By choosing to fundraise for IWF, you can turn your fitness challenge into real impact. Register today and help us create a safer internet for children.
