Block AI-powered fraud before it reaches your platform

Secure every user interaction with AI-driven deepfake detection that adapts to emerging threats.

Block AI-powered fraud before it reaches your platform

Secure every user interaction with AI-driven deepfake detection that adapts to emerging threats.

The deepfake threat isn't coming, it's already here

Deepfakes and synthetic media are now standard tools in the fraudster's playbook.


  • Generating synthetic selfies that slip past basic image checks 

  • Injecting fake videos directly into liveness verification flows 

  • Manipulating document videos with static images disguised as genuine recordings 

  • Coordinating attacks across borders to exploit regional verification blind spots 

The cost of missing these attacks? Account takeovers, financial losses, and regulatory penalties that could have been prevented.

Stop deepfakes at every layer

Selfie Deepfake Detection

Identifies and blocks AI-generated or digitally altered selfie images in real time.

Liveness detection

Verifies active human presence and filters out replays, masks, and synthetic identities.

Document Video Analysis

Authenticates identity documents captured on video, detecting static image injection and manipulation.

Location & Behavioural Analysis

Adds contextual intelligence—flagging suspicious patterns across location, device, and behaviour.
