Deployed for the past 35 years, SS7 provides signaling that enables mobile and fixed network operators to setup/teardown calls, to route text (SMS) messages, support inter-network connectivity and transparent roaming, and to provide per-session information such as caller ID. Today SS7 is a critical part of the global telecommunications infrastructure. Because SS7 networks were originally designed to work within an operator’s trusted domain or to interwork between trusted operators, security was not a top design consideration nor were potential SS7 vulnerabilities adequately addressed.

Ribbon has partnered with Cellusys to provide a multi-layer security solution that leverages existing STP gateway screening capabilities and incrementally adds Signaling Firewall capabilities needed for context-sensitive assessment on SS7 messages.
