What is the difference between SMS Verify and Verify Plus?

SMS Verify delivers phone-based verification and MFA using a time-based, one-time passcode (OTP).  Verify Plus does the same thing, but layers in a dynamic risk assessment score to determine a user’s risk before an OTP is deployed. Verify Plus is an add-on that enhances fraud detection and prevention.

What does machine learning (ML) evaluate?

Telesign’s proprietary and customizable machine learning model evaluates phone data attributes, global traffic patterns, and phone number intelligence to uncover hidden insights to predict fraud and risk.
