Who we are

Founded in 2012, Callsign’s mission is to power the identification of every web, mobile and physical interaction seamlessly. To do this, we hire the brightest, most inquisitive minds who want to change the rules of identity and make this mission a reality. Callsign products use deep learning techniques to combine event, threat and behavioural analytics with multi-factor authentication, securing access to services while uniquely establishing the most frictionless and transparent user experience. We provide risk intelligence in real time, enabling organisations to adjust authentication journeys intelligently, also in real time. By pinpointing suspicious access attempts, we can step up and step down the authentication requirement, catching fraudulent activity more effectively while simultaneously removing friction for legitimate users.

Apart from looking to keep people safe from bad guys, we are also looking to make their digital lives better with ubiquitous technology that works for all, regardless of circumstance.
