Fraud Management System
Subex’s Fraud Management System (FMS) uses advanced AI and GenAI to proactively detect, investigate, and prevent telecom fraud. It employs AI and ML models and rules to identify patterns and highlight anomalies, while AI investigative agents investigate the resulting cases and provide actionable insights. With decades of experience, the system unifies data, automates workflows, and turns complexity into clarity. Scalable and flexible, it evolves with your business to ensure continuous improvement and adaptability. This empowers operators to protect revenue, safeguard networks, and combat new threats with confidence and agility.
Features
Rule Modeling
Configurable rule management for usage- and transaction-based fraud across lines of business, deployed in real time via the detection engine. Supports advanced rule types such as threshold, geographic, pattern, hotlist, sequential patterns, dedupe, trend/anomaly; and pairs well with ML-based techniques for adaptive detection.
Fraud Dashboards and Analytics
Built-in dashboards and reports for analyst performance, rule performance, case insights, plus a flexible report builder to create custom dashboards and visualizations e.g., maps, line, heatmaps, scatter, combo charts from diverse data sources.
Link Analysis
Visualize syndicates and relationships using force-directed graphs across entities like numbers, accounts, IMEI, destinations. Includes pre-calculated metrics, in-graph actions (flag, create case, hotlist), and integrated retrieval to enrich investigations with additional context.
Data Management
Flexible, scalable ETL to onboard new data streams quickly. Provides advanced data mapping (string manipulation, lookups, bulk load) and supports batch, micro-batch, streaming, and API integrations.
Case Management
Embedded case management captures alerts and helps teams prioritize cases. SOPs can be configured as guided workflows so analysts investigate and resolve within SLAs.
Signalling Risk Intelligence
Monitors control-plane signaling to detect and prevent fraud earlier—especially for scenarios better identified at the signaling layer e.g., Wangiri, IRSF, CLI spoofing, A2P SMS bypass. Built on a future-ready architecture that adapts to emerging telecom protocols
User Management
Role-based access control with configurable password policies, multi-role switching, and built-in authentication support including LDAP/IDM and SAML 2.0-based options.
Comprehensive Fraud Intelligence
Subex Risk Intelligence Database e.g., suspect/test numbers, high-cost destinations, unallocated ranges, number validation is updated regularly. Intelligence auto-updates relevant rules, improves tagging of event attributes, and can also act as seed data for ML training/re-training.
List Management
Maintain Priority/Watch/Allow/Block lists and match across key fields such as caller/called number, country, cell sites, equipment ID, etc. Includes auto-expiry to keep lists clean and reduce false positives over time.
Integrated GenAI
Subex FMS uses industry leading Generative AI (Large Language Models based) agents, “Gen AI agents” to transform fraud investigation and operations. Acting as intelligent assistants, these agents analyze vast data in real-time to uncover patterns and reduce investigation time.
By automating tasks and enhancing investigation accuracy, they enable proactive responses and free analysts to focus on complex fraud scenarios which require extreme domain expertise. This ensures telecom operators stay ahead of evolving fraud tactics, safeguarding revenue and efficiency.

Frequently Asked Questions
Everything you need to know about how our fraud management solutions work.
How is Subex’s Fraud Management different from traditional fraud detection systems?
Traditional systems react after losses occur. Subex uses real-time scoring, behavioural intelligence, and AI-driven anticipation to surface threats the moment they emerge—across identities, subscriptions, roaming, digital payments, and partner channels. The goal is prevention, not post-incident discovery.
