S21 Investigator Wellbeing helps teams monitor exposure patterns, reduce unnecessary contact with traumatic material, and support healthier long-term investigative practices.
Global victim identification intelligence at unprecedented scale.
The S21 Global Alliance Database contains over 3.5 billion law-enforcement-contributed intelligence records from trusted partners worldwide, helping investigators identify victim status, uncover cross-case links, and surface critical investigative intelligence at global scale.
Investigators can only act on the evidence they can see
Unsupported formats, failed processing, and evidence that never becomes searchable can create critical blind spots within digital investigations.
Investigators may therefore make decisions without visibility of the full dataset.
S21 tools are designed to reduce those gaps - helping investigative teams review more evidence, surface relevant intelligence faster, and work with greater confidence.
Trusted by investigators working complex digital investigations.

"VisionX is a powerful and vital tool to any Digital Forensic Analyst. I highly recommend it to be part of your forensic software toolbox. The S21 Auto-Categoriser quickly identifies the majority of CSAM images in your case and allows the Investigator to streamline the categorisation process."
