18% employee growth in 12 months
Our take
Callsign uses deep learning technology to analyse a variety of real time signals such as the GPS location, force of touch and screen co-ordinates to identify potentially suspicious usage of a device. Collaborating with Lloyds bank, the company's technology helps to mitigate unauthorised access while providing a seamless user experience.
Callsign is not the only company in this area, and faces competition from other firms such as AimBrain, Behaviosec, and BioCatch. To stand out, its AI system takes into account a combination of different factors to improve its accuracy and reliability. It has also built security in, with all data encrypted on the device itself before being sent to the server.
