PROTEI is thrilled to announce the launch of its cutting-edge Unified Signaling Shield (USS), a Multi-Protocol Signaling Firewall designed to empower Communication Service Providers (CSPs) to effectively monitor, control, and manage signaling traffic with both national and international operators, carriers, and telecom service providers.

In today’s digital landscape, it is crucial for CSPs to protect networks against various threats, including protocol vulnerabilities, subscriber data exposure, and unauthorized location tracking, across protocols such as SS7, Diameter, and GTP-C. Additionally, challenges like voice call misuse, including Wangiri scams, robocalls, CLI spoofing, and Flash calls, necessitate robust protections. PROTEI Unified Signaling Shield extends further by implementing proprietary rules based on vast market experience and deployment expertise.

Malicious actors are not restricted to single protocols; they exploit interfaces to achieve their ends. Recent attacks demonstrate increasing complexity and sophistication, especially those driven by nation-states. Such attacks, executed across multiple protocols simultaneously, could escape detection if protocols are isolated from one another.

PROTEI Unified Signaling Shield operates as a comprehensive multi-protocol firewall, safeguarding SS7, Diameter, GTP-C, SIP, and ISUP protocols. By utilizing a unified platform to process signaling across all protocols, the USS enables real-time correlation during active processing, as opposed to relying solely on post-processing or reporting. This capability allows the USS to effectively counter sophisticated, multi-protocol attacks by detecting and blocking them in real time.

PROTEI USS is also equipped to identify and address unexpected or unconventional signaling messages by applying appropriate MTP, SCCP, TCAP, and MAP policing rules. It features intuitive dashboards that provide CSPs with a clear overview of ongoing activities and how USS is managing these threats.

Furthermore, PROTEI USS complies with GSMA guidelines FS.11, FS.19, FS.20, and FS.36, covering all aspects of GSMA’s Category 1, 2, and 3 security recommendations. It surpasses these standards by detecting unusual low-level activities, signaling inconsistencies, and other anomalies.
