Account takeover

Fight fraud and empower genuine users with a digital ID that stops account takeover (ATO) in its tracks.

Account takeover prevention

True positive identification

The only way to truly prevent account takeover is to be certain that the user is who they claim to be. Our industry-leading AI uses advanced behavioral biometrics, location analysis and device fingerprinting techniques to passively determine the user's identity – denying access to bad actors, even if they know their username and password.

Preventing ATO in banking

Start More Certain

Whether it's password breaches, bots or shared credentials, you don't want anyone but the genuine user accessing their account. Our industry-leading, cross-browser device fingerprinting and other intelligence factors protect against account takeover.
