Voice Firewall
Mobileum’s Voice Firewall uses AI-driven analytics to block robocalls, spoofing, and telecom voice fraud. Protect your network and ensure STIR/SHAKEN compliance.
Validate your signaling firewall post-upgrades with Mobileum’s automated testing platform. Reduce risks and ensure network security before going live.
Mobileum’s Automated Signaling Firewall Testing enables telecom operators to proactively validate firewall performance in lab settings before changes go live. Built on the dsTest platform, it simulates real-world threats across SS7, Diameter, GTP, and HTTP/2 protocols — ensuring every upgrade or rule change maintains security effectiveness. With repeatable, automated test cycles, Mobileum eliminates manual risk and accelerates validation across complex signaling environments.
Every rule update or configuration change can expose critical vulnerabilities. Mobileum helps operators close that risk gap with AI-powered, standards-based testing that replicates sophisticated threat scenarios. By simulating attacks before live traffic is exposed, operators gain assurance that firewalls will perform under pressure—enhancing security, reducing incident response time, and supporting compliance.

The Tier 1 US operator needed to perform pre-production validation of the changes to ensure that the signaling firewall did not expose any vulnerabilities before deployment. This needed to be an automated process.
dsTest was used to automate testing of signaling firewall changes by emulating SS7, Diameter, and GTP-C traffic with existing libraries. Integrated with TSAR, the solution enabled rapid, scheduled validation of firewall rule changes to ensure continued security and eliminate vulnerabilities.
