New partnership helps tackle the ‘hardest and most important work’ in trust and safety online: child sexual abuse material

Published:  Wed 16 Sep 2026

Musubi, a tech company that supports platforms to defend and respond to trust, safety and fraud concerns, has joined the Internet Watch Foundation (IWF) to help fight the spread of child sexual abuse material online.

The partnership brings together Musubi’s AI-native trust and safety technology with the IWF’s trusted intelligence and expertise, helping online platforms identify and block child sexual abuse images and videos more effectively.

Musubi works alongside digital platforms to address some of the internet’s most complex safety challenges by providing tools that enable organisations to build trust and safety systems tailored to their own policies, services and risk environments. Today, Musubi's technology helps protect more than 850 million end-users around the world.

By becoming an IWF Member, Musubi gains access to the IWF’s reliable datasets such as the IWF URL List, Image Hash List and Keywords List. Eligible IWF Members using Musubi’s platform will be able to access IWF datasets directly within the tools they already use, enabling faster identification and prevention of child sexual abuse images and videos online.

The integration enables platforms using Musubi’s services to deploy proven protections more quickly, helping prevent the distribution of criminal child sexual abuse content while allowing trust and safety teams to focus on the complex decisions that require human expertise and judgement.

Musubi believes that no safety concern matters more than protecting children online and that preventing the spread of child sexual abuse material requires proactive, accurate and rapid detection. By acting swiftly, harmful content can be stopped before it can circulate more widely and cause further harm to victims and survivors.

Alice Hunsberger, Head of Trust & Safety at Musubi, said: “Anyone who’s worked in trust and safety knows that child sexual abuse material is the hardest and most important work. We started Musubi to give platforms a better way to solve their safety problems, and none of them matters more than protecting children.”

“Musubi’s IWF membership means the platforms we serve can put the IWF’s expertise to work inside their own systems, with far less effort than going it alone. We’re proud to stand with the IWF and its Members on fulfilling this responsibility.”

Kerry Smith, Chief Executive Officer of the IWF, said: “Sadly, the volume of child sexual abuse material being shared online continues to rise at an alarming rate. Last year, IWF experts actioned more than 311,000 webpages or links depicting the sexual abuse of children.

“This makes collaboration with like-minded organisations critical to the global effort to tackle child sexual abuse material online. We welcome Musubi on board as a new IWF Member, strengthening our collective ability to identify and remove more of this horrific material.”
