Diameter Firewall (BroadForward DFW) is a complete and advanced software-based solution that protects 4G networks against potential attacks, unauthorized senders, malformed messages, overload situations, and much more.
Diameter Firewall (DFW) is in use with leading mobile operators around the world. The DFW provides operators with a default set of firewall rules that implement the GSMA specifications FS.19. None of the firewall rules in the system are ‘hard-coded’ and can therefore be adapted for/by the operator as required.

The DFW reduces the window of opportunity for criminals to exploit a breach on their mobile network. It detects and blocks duplicated SIM or SIM swap fraud in real-time by performing velocity tracking. This unique feature automatically determines – with a high degree of accuracy – whether roaming location changes are plausible in terms of the speed normally required to bridge that distance (‘time-distance plausibility’).
The easy-to-use Graphical User Interface provides full control of firewall rules and insight into signaling traffic. It gives extensive flexibility to configure, adapt, enable or disable firewall rules that can be deployed across all supported access technologies. The use of readily available templates means operators do not require vendor involvement, scripting or coding to manage or customize firewall rules.
The BroadForward DFW will improve the operator’s effectiveness in dealing with unexpected (fraudulent) behavior and significantly increases roaming security. The BroadForward DFW offers major differentiators compared to traditional firewall products:
The GSMA regularly releases updates to its guidelines for “Diameter Interconnect Security” also known as the FS.19 recommendations. In general, these recommendations define the following four categories:
