Telecom Signaling Security
Service Overview
Signaling networks carry the messages that make calls connect, subscribers roam, and data sessions stay authenticated - which makes SS7, Diameter, and GTP prime targets for abuse. Rutters Solutions tests these interconnects the way an attacker would, tracing paths to location disclosure, fraud, interception, and service disruption before they surface in production.
A named senior consultant owns each engagement from scoping through remediation review, so you always have a single, accountable point of contact with real hands-on telecom security experience.

Key Capabilities
A structured methodology for probing and hardening signaling network environments.
In-depth SS7 network testing that surfaces subscriber-tracking, call-interception, and fraud exposure.
Independent review of LTE signaling perimeters and roaming interconnect trust boundaries.
Targeted assessment of GRX/IPX interconnects to close off spoofing and data-leak vectors.
Controlled attack simulations that verify whether deployed signaling firewalls actually hold.
Why Rutters
Every telecom security engagement is run by practitioners who have built and operated carrier networks, not just tested them.
We probe using the exact tradecraft real adversaries rely on, so findings reflect genuine risk.
Methodology mapped directly to the GSMA FS.11 (SS7) and FS.19 (Diameter) baselines.
Purpose-built tooling surfaces undocumented logic flaws that standard scanners miss.
Practical, implementation-ready guidance on STP/DRA routing and firewall rule design.
