Our take
Persona enables businesses to verify customer identities, fostering trust in online interactions and aiding in age verification, fraud prevention, and account recovery. It offers a comprehensive suite of automated identity verification components with worldwide coverage that can be configured, branded, and themed to create custom-tailored flows for any use case
Businesses and governmental organizations can access Persona’s platform via an API, which supports various documents from government-issued IDs to biometrics, ensuring customers are who they claim to be. Persona’s platform also collects passive signals such as a user’s device, location, and behavioral patterns to provide a more holistic risk profile, beneficial in financial and insurance contexts
Recently, Persona partnered with Member Driven Technologies (MDT) to enhance identity verification for credit unions. This partnership enables credit unions to adjust their identity verification flows in real-time based on risk signals, improving user conversion and fraud deterrence. The collaboration aims to streamline operations and strengthen fraud prevention, both digitally and in branches. Since founding, Persona has been scaling its offerings and now boasts a worldwide presence, serving clients in nearly every country and supporting 20 languages.
