Our services
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.
We currently assess over 7,000 reports per week. It’s a tough job, but our analysts are global experts in the field. We support them to do an extraordinary job.
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.
Today, over 190 tech companies including some of the giants of the industry, have signed up to use our services. They trust our analysts and services. They respect our tech-for-good developments. They share our vision to put an end to child sexual abuse imagery online.
