HAUD’s probe solution is a non-intrusive solution that is set-up to monitor any leakages from A2P SMS.


SMS tests are sent by HAUD, simulating subscriber traffic and capture details of the SMS traffic received on the probe including traffic source, Sender ID other details. A centralised back end collates the data which is then analysed to identify suspicious activity as well as providing reporting on trends and new threats or showing the effectiveness of currently used controlling mechanisms of solutions.
