What is the practical value of our MNO SMS Firewall service?

Unauthorized Routes Identification

Tactics involving unlawful routes encompass traffic blending, off-net termination, SMS delivery via local aggregators, and other methods such as SIM Boxes (also known as SIM Farms). Our ENQUIRELINK MNO SMS Firewall facilitates identifying and managing any form of illicit routing.

SIM Boxes (SIM Farms) Fighting

These devices contribute to revenue loss for Mobile Network Operators (MNOs). Combatting these prepaid Peer-to-Peer (P2P) SIM card activities demands a solution that effectively tackles aggressive and sophisticated techniques. With the ENQUIRELINK SMS Firewall, mobile network operators can mitigate revenue loss while enhancing subscriber satisfaction.

Flooding Prevention

SMS flooding attacks involve a barrage of A2P messages aimed at overwhelming the Mobile Network Operator’s (MNO’s) Mobile Switching Center (MSC). Our MNO SMS Firewall identifies potential flood attacks by scrutinizing originating GT parameters and ensures the highest SMS security.

GT Scanning

This malicious scanning attack aims to locate OPEN SMSCs to terminate traffic without charge. Primarily targeting Mobile-Originated (MO) Traffic, GT Scanning involves sending MO_FWD to a range of GTs to pinpoint a vulnerable SMSC. ENQUIRELINK detects potential GT Scanning activities by monitoring FWD SM-MO packets.
