As the SS7 network constitutes the main interconnection backbone among telephone operators, even more people depend on it daily to communicate with each other. Along with its expansion, SS7 network suffers from constant attack surging by fraudsters, hackers and adversaries, exploiting loopholes in the protocol to breach subscriber privacy, deny access to key services and to directly defraud mobile operators. Our SS7 Firewall completes our SMS Firewall and secures the internal network without interruptions.
