S21 Deepfake Detector
Detect manipulated and synthetic media when authenticity matters
When video or imagery may be manipulated, delays or uncertainty can undermine safeguarding, intelligence, and evidential decisions.
S21 Deepfake Detector enables investigators to assess whether images or video frames have been synthetically generated or digitally manipulated — quickly, offline, and without reliance on external services.
Built specifically for investigative and safeguarding contexts, it provides an additional layer of confidence when authenticity is in question.
Why this capability matters
When authenticity is uncertain, investigative risk increases
In an era of increasingly accessible synthetic media tools, investigators are encountering manipulated or AI-generated imagery and video more frequently — sometimes intentionally deceptive, sometimes unknowingly shared.
Without reliable indicators, time can be lost assessing credibility, evidential value, or safeguarding relevance.
Faster authenticity assessment
Move from suspicion to informed judgement in minutes — without specialist expertise.
Consistent, repeatable analysis
Apply the same detection methods across cases, teams, and time.
Stronger evidential confidence
Support intelligence, safeguarding, and court decisions with documented analysis.
One focused capability. One clear investigative outcome.

Assess potential manipulation indicators without relying on external tools or prolonged review.
How S21 Deepfake Detector works
Investigators may encounter video or imagery where authenticity is unclear — from social media clips to seized media files.
S21 Deepfake Detector is a standalone, offline investigative tool that analyses images and video frames for indicators of synthetic generation or digital manipulation.
It evaluates visual artefacts, inconsistencies, and patterns commonly associated with manipulated or AI-generated media — presenting results in a clear, investigator-friendly format.
