About
Callsign is a digital identity and authentication company founded in 2010 and headquartered in London, United Kingdom. The company builds an intelligent authentication platform that verifies user identity through multiple simultaneous signals — behavioral biometrics (how a user types, swipes, and moves a device), device intelligence (device fingerprinting, SIM state, GPS data), and contextual risk signals — in addition to traditional multi-factor authentication methods. By combining these layers into a single authentication decision, Callsign claims to achieve recognition accuracy of up to 99.999%, enabling frictionless authentication for legitimate users while flagging anomalous sessions for step-up verification or fraud review.
