HAUD’s Signalling Firewall for SS7 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 Signalling 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 SS7 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.

SS7 Protection Key Features

SpoofGuard and FakeGuard

Prevent spam and fraudulent traffic from being sent through your network to mobile subscribers worldwide, by Identifying and also blocking, all spoofing and faking attempts.


Automatically detect spikes in traffic and apply messages per second (MPS) thresholds to suspect sources, ensuring your network is not targeted by denial of service attacks.


Block requests for network or subscriber information, as well as other SS7 category 1 fraud, coming from outside your network, ensuring that subscriber privacy is respected and that MAP opcodes are used only by legitimate interconnect partners.
