Signalling Firewall
The Signalling Firewall inspects and controls signalling traffic across SS7, Diameter, GTP, SIP and HTTP/2 — the protocols that underpin mobile network interconnect. It operates at interconnect boundaries to identify and manage signalling activity that is invalid, unexpected, or indicative of known attack patterns.
The platform applies configurable, protocol-aware rules in real time, aligned with GSMA recommendations and operator policies. It detects and mitigates threats such as unauthorised signalling queries, subscriber data exposure, and attempts to manipulate network behaviour across both legacy and IP-based environments.
Actions can be configured per policy, including blocking, modification, rate limiting, or alerting. All activity is logged and made available for analysis, enabling operators to review traffic behaviour, refine rule sets, and maintain visibility across signalling layers.
The firewall supports multi-protocol, multi-interface deployments across SS7, Diameter, GTP, SIP and HTTP/2, covering both legacy and next-generation interconnect scenarios within a single integrated platform.
