HAUD’s Firewall for Security & Protection defends your network against a wide range of SS7 vulnerabilities, including flooding, GT scanning, faking, spoofing and the incorrect use of MAP protocol.


The Firewall monitors all incoming international and local SS7 traffic on your network, capturing and blocking the illicit use of SS7 signalling. It controls SS7 category 1, 2 and 3 fraud, enabling you to maintain the integrity of your network.

360-degree network protection is enforced through the use of the Firewall’s pre-emptive BulkGuard module. This identifies spam and fraudulent traffic, such as Wangiri, SMiShing and malware, allowing you to neutralise threats at source.



Key Features
