Mobik SMS Guard is a managed solution designed to detect and block fraudulent SMS traffic on mobile networks. The product targets grey route SMS fraud, including illegal A2P (Application-to-Person) and P2P (Person-to-Person) bypass traffic that causes revenue leakage for mobile network operators. The solution operates as a fully managed service that can work with or without an SMS firewall, including the ability to manage existing third-party firewalls. It detects fraudulent messages in real-time without requiring reconfiguration of network elements or inspection of SMS message content, making it GDPR compliant. SMS Guard blocks abused routes to force SMS traffic migration to authorized routes, increasing the volume of billed A2P traffic. The platform includes capabilities for two-way SMS communication, automated billing, invoicing, reporting, campaign creation, and automated package creation. It provides a secure web interface for administrators with multiple user account support and can be white-labeled and deployed on-site or in the cloud. The solution uses globally distributed test probes that are fully scalable and configurable. It offers detailed metrics and reporting with visualization capabilities, allowing operators to assess specific destinations, operators, SMS hubs, OTTs, and applications. The system is designed as a carrier-grade, fully redundant solution with no single point of failure. Mobik positions this as a revenue assurance solution that operates on a revenue share model, requiring zero CAPEX and zero OPEX from operators, with deployment possible within 24 hours of agreement.
