  • AI to identify CSAM, and junk filtration to hide irrelevant content
  • Identify keywords, suspicious apps and files nearby POI of interest (e.g. schools, airports)
  • Device make, model, serial and GPS analysis

Dynamically adjusts based upon your evidence

Automated workflows identify and prioritise high risk areas of evidence, scanning these first to discover notable content faster.

  • Supports E01, L01, VMDK, physical / logical disks and directories
  • Generates a directory breakdown of evidence in seconds
  • Stop-start scanning enables you to immediately select and analyse suspicious directories

Automate Victim Identification

The S21 Assisted VID enables everyone to conduct thorough victim identification searches, quickly and with ease.

With the S21 Assisted VID investigators can provide minimal ‘breadcrumbs’ of information and the automated AI will do the rest, highlighting possible files containing victims.

Like you we believe every victim matters, and now everyone can help identify victims, even at triage.

S21 Auto-Categoriser

Automated categorisation of CSAM images and videos

The S21 Auto Categoriser built into S21 Discovery enables users to process thousands of images and videos per minute to find illicit content.

Able to differentiate between CSAM, indicate content, legally held content and adult pornography, the S21 Auto Categoriser significantly reduces categorisation time, while potentially highlight victims from the start. 

S21 Global Alliance Database

Contains over 2 billion CSAM & CT related records, including media notes and descriptions, designed to reduce your manual review and over exposure to CSAM material.
