Mobik Data Guard is a fraud prevention and revenue assurance solution designed for mobile network operators. The product uses NGE-DPI (Next-Generation Enhanced Deep Packet Inspection) technology powered by AI and Machine Learning to analyze network traffic in real-time. The platform analyzes over 3,500 applications and protocols, including encrypted traffic such as HTTPS, SSH, and VPNs, using more than 5,500 metadata points. Data Guard addresses data fraud that can result in revenue loss of up to 5% in competitive prepaid mobile markets. The solution detects and prevents zero-rate charging exploitation through methods including HTTP header injection, domain fronting, and DNS spoofing. It monitors data revenue leakage by performing network scans that measure data usage and detect control problems and billing issues. The collected data enables point-to-point comparison with business support systems and can serve as backup for billing calculations. Data Guard implements Fair Use Policy management to ensure network resources remain available during peak times by limiting specific users or groups. This preserves Quality of Experience for the majority of users while increasing network efficiency. The platform provides real-time dashboards for all data traffic and offers 24/7 global support. It scales to any mobile network size without limitations on concurrent subscribers or total subscriber base.
