CaseScan is a CSAM detection platform serving two audiences: law enforcement agencies and user-generated content platforms. For ICAC units and digital forensic examiners, it runs on-device with no internet connection required, scanning suspect devices and returning triage results in minutes without uploading data to external servers. For UGC platforms and content hosts, it provides an API that scans images and video at ingest using AI models and perceptual hashing to detect both known CSAM and previously unseen or AI-generated content. Deployed by major platforms including Wix and DoubleVerify, and used by 100+ law enforcement agencies, scanning 2 billion+ files per day.
