Callsign Platform is a behavioral authentication and digital identity solution built around three core components: **Intelligence Engine** Uses machine learning ensembling, behavioral biometrics, device fingerprinting, and telco intelligence to passively authenticate users and detect threats. It continuously learns from user behavior to distinguish legitimate users from potential fraudsters without introducing friction. **Orchestration Layer** A code-free, drag-and-drop interface for managing end-to-end user authentication journeys. It allows organizations to design, test, and deploy authentication processes and controls without writing code. Supports zero-risk testing and provides audit and review capabilities. **Authentication Suite** Provides multi-factor authentication (MFA) covering the three authentication factors: knowledge (something the user knows), possession (something the user has), and inherence (something the user is). Designed to work across devices and locations. **Integration & Deployment** The platform supports cloud-native deployment with both multi-tenant and single-tenant options. It integrates with existing legacy infrastructure and supports horizontal and vertical scaling for availability. The platform is designed to help organizations reduce friction for legitimate users, detect and block fraudulent access, meet regulatory compliance requirements, and consolidate multiple authentication and fraud-prevention vendors into a single solution.
