A list of ‘digital fingerprints’ of known child sexual abuse imagery allowing you to stop it on your networks, platforms and apps.
We work with the tech community, governments, law enforcement agencies and other hotlines globally. We believe that this is the only effective way to tackle a problem that doesn’t respect borders, laws or the rights of children worldwide.
What we do works. Our analysts track down a harrowing criminal image of a child being sexually abused every two minutes. The child, their suffering, the abuse, is real. We make sure that record of trauma is removed. Then we work to prevent it being uploaded again.
Our work is impressive. But it’s not enough. We won’t rest until every single record of a child being sexually abused has been removed from the internet. Our Members share this ambitious goal.
We provide a unique range of services to help our Members defend their customers, staff and children, wherever they are in the world.
