Automate Victim Identification
The S21 Find Victims function (previously Assisted VID) enables everyone to run thorough victim ID searches quickly and easily.
Investigators provide minimal ‘breadcrumbs’ of information — S21 Discovery’s AI does the rest, highlighting possible files containing victims.
Like you, we believe every victim matters. Now, anyone can help identify and safeguard victims faster than ever.
Automated categorisation of CSAM images and videos
The S21 CSAM Auto Categoriser, built into Discovery, enables users to process thousands of images and videos per minute to identify illicit content.
It differentiates between CSAM, indicative content, legally held content and adult pornography — significantly reducing categorisation time and easing the mental burden on investigators.

Fully Offline & Secure
Protect sensitive evidence and eliminate the risks of cloud-based AI learning from your victims’ images and videos — and potentially exploiting them further. S21 Discovery runs completely offline, ensuring no data ever leaves your environment and removing all exposure to third-party access or breaches.

Built for Everyone — from Frontline Officers to Lab Experts
S21 Discovery is easy to use for simple frontline users and powerful enough for advanced lab analysts. Whether you’re on the front line or in the lab, it provides the right tools to get the job done.

No Servers or Specialist Hardware
Deploy instantly without complex infrastructure. S21 Discovery runs efficiently on standard workstations or existing networked machines — no dedicated servers or high-end hardware required.
Easily Scan and Create Cases
Set up a new case in moments and quickly scan devices or media for relevant content. S21 Discovery highlights key files early in the process, helping you prioritise evidence and focus on what matters most without unnecessary delays.
Instant CSAM Detection
Automatically detect and flag CSAM within scanned devices and media. S21 Discovery identifies high-risk material early, reducing investigator exposure and ensuring critical evidence is prioritised for review and action.
Flag Files of Interest
Mark important files with flags to keep them organised and easy to revisit. Whether highlighting potential evidence or noting items for further review, flagged files remain clearly visible throughout the case for faster access and decision-making.
Report Generation
Create detailed, professional reports directly from your case with just a few clicks. Include flagged files, key findings and supporting details in a clear format that is ready to share, review, or submit as part of your investigation.
