Industry experts have been warning for many years about SS7 security concerns and how SS7 can be abused to redirect calls, track locations, and capture text messages. SS7 is very slowly being replaced by newer signaling protocols like Diameter, but during this extended period of gradual migration, these security holes remain very much a concern.

These security holes are being exploited with vigor and determination by fraudsters worldwide, targeting both networks and their subscribers. This has driven the sustained growth of an ever-expanding set of signaling
derived fraud, saddling operators with enormous financial losses, lowered customer satisfaction (CSAT) and subscriber churn.

It is clear that operators need to secure their SS7 signaling architecture in a way that addresses not just  these already well-known concerns, but also allows operators to protect their networks in real time against newly emerging threats, without having to wait for a vendor-provided solution.
