Callsign is a behavioral authentication and intelligence platform that helps organizations recognize genuine users naturally, securely, and without friction. At its core is the Intelligence Engine, which uses ensemble machine learning, behavioral biometrics, device fingerprinting, and telco intelligence to passively authenticate users and detect fraudulent activity in real time. The platform identifies users based on their unique digital behaviors rather than requiring intrusive authentication steps, delivering seamless experiences across account login, online payments, account creation, and zero trust network access.

The Orchestration Layer enables organizations to design, test, and deploy end-to-end customer journeys through a code-free drag-and-drop interface. Dynamic interventions allow teams to update and release new authentication controls without engineering dependency, providing agility against an evolving threat landscape. The Authentication Suite supports multi-factor authentication across knowledge, possession, and inherence factors, and includes Callsign One for streamlined, device-native authentication.

Callsign addresses a comprehensive range of fraud vectors including account takeover, social engineering and scams, bots and malware, SIM swap and call divert, and synthetic identity fraud. For compliance, the platform supports PSD2 and Strong Customer Authentication as well as KYC and AML workflows. Organizations in financial services can expect to see savings of up to 40% over five years according to site claims, while a proven 83% reduction in fraud from digital impersonation is cited for bot and malware threats.

The platform is cloud-native, horizontally and vertically scalable, and designed to integrate with existing infrastructure regardless of where an organization is in its digital transformation journey. Callsign is built on ethical AI principles with privacy at the forefront, ensuring solutions remain compliant with existing and future privacy regulations.
