Let's protect the A2P SMS ecosystem

IRSF (International Revenue Share Fraud) is escalating, including SMS AIT (Artificially Inflated Traffic) incidents. Calls and SMS to IPRNs (International Premium Rate Numbers) are being hijacked on a regular basis and it's getting harder to distinguish legitimate calls and SMS from AIT. In addition, AI technology is being used to intensify SMS AIT, generating millions of fake SMS, in particular, One Time Passwords (OTPs). All this is a major risk to business messaging.​

Stop IRSF before it even starts

Existing solutions are about detection after the fraud has happened. The GSMA’s new service is the first one that enables you to prevent IRSF attacks from occurring in the first place through the swift gathering and aggregation of data, which is faster than AI.
