Callsign Orchestration Layer is a platform component designed to unify disparate security and fraud detection systems through a code-free integration and policy management interface. The product enables organizations to connect existing technologies and systems without writing code, using a plug-and-play policy manager and a graphical user interface (GUI). It is aimed at security and risk management teams seeking to reduce reliance on point solutions by consolidating online fraud detection (OFD) capabilities through orchestration. Key functional areas include: **Policy Management:** Provides an environment for developing, testing, and deploying customer journey policies. Non-technical analysts can build and manage policies through a no-code interface, with built-in workflows and approval models to ensure only approved policies go live. **Testing and Simulation:** Supports simulation, A/B testing, and Champion/Challenger testing to validate policies and processes before production deployment, reducing risk during rollout. **Code-Free Integration:** Allows organizations to connect multiple systems and technologies without custom development, using the GUI-driven policy manager to launch and modify processes quickly. **Real-Time Orchestration:** Uses a multi-model approach to expose multiple levels of data, enabling dynamic and tailored customer journey experiences that balance fraud risk and user experience in real time. The solution is positioned as an orchestration layer within Callsign's broader platform, addressing the complexity of modern fraud detection stacks as referenced in Gartner's Market Guide for Online Fraud Detection.
