Cellusys systems can be an instrumental tool in combating fraud targeting your network or subscribers


Signalling Firewall

Functions as an active probe that can feed real-time GTP-C, SIP, SS7, and Diameter traffic data to third-party systems or send reports to specialized fraud teams.

The firewall can then enact rules based on these recommendations, as well as industry recommendations and other discovered threats.

Discover fraudulent patterns and block known fraudulent IMSI ranges, or implement customised rulesets using the user-friendly GUI.


Mobile Broadband Analytics

Functions as a passive probe that can feed full GTP-C (control plane) and GTP-U (user plane) traffic data to third party systems in real time, or send alerts and reports to specialized fraud teams to enable accurate analysis and detection of fraud.

Alerts and reports are fully customisable and easy to set up for everyone on your team thanks to the user-friendly GUI.

SMS Firewall

Protection against various kinds of SMS fraud including spam and A2P fraud.

Spam events can be automatically detected and blocked. After a fraudulent or suspicious A2P SMS has been blocked, the message sender can be informed that their message was delivered, when in fact it has been removed from the network. Alternatively, grey or suspicious A2P SMS messages can be modified to include a warning to the recipient.
