NSI Network Sentry | SS7 Intrusion Detection and Firewall System

Available to Network Operators, Corporate, and Government

NSI Global’s Network Security Systems as well as our SS7 vulnerability testing and consulting services allow mobile network operators, telecommunications regulatory authorities, and public safety and security agencies to defend themselves against illegal interception, user tracking, manipulation, and fraud on the network level, covering the entire signal chain from edge to core.

NSI Global along with its European based COMSEC, developed the NSI Network Sentry system which is comprised of:

Sentry Detect – a comprehensive intrusion detection system that is capable of identifying protocol violations and/or misuse by fraudsters and other unauthorised foreign or domestic entities. Using high-performance real time analysis as well as a state of the art monitoring rule set with automatic updates, Sentry Detect permits network operators to identify and report threats.

Sentry Block – Sentry Block utilises the same analysis system as Sentry Detect. It is a sophisticated active SS7 firewall that can automatically block illegal traffic at each SS7 Signal Transfer Point, thus preventing such traffic from penetrating the core network.

SS7 & Diameter Vulnerability Testing and Consulting

With our core network penetration tests, NSI Global offers the most comprehensive signalling network vulnerability assessment in the industry.

We help you to protect your core network’s Achilles heel against subscriber privacy violations, illegal interception of calls, messages and data theft, billing fraud, denial of service, network settings manipulation, and provide further network tests. All tests performed are including but not limited to GSMA FS.11 Category 1-4 recommendations and are valid for 2G, 3G, 4G and 5G.

NSI Global has provided SS7 vulnerability testing and consulting to mobile network operators in Europe, North America, Africa, the Middle East and Asia.
