GTP (GPRS Tunnelling Protocol) defined by the 3GPP standards, has been a fundamental protocol in the evolution of mobile networks. Over the years, GTP has evolved from connecting and enabling seamless roaming access in GPRS to acting as a liaison between old and new technologies across 3G and 4G.
The GTP protocol, designed for legacy networks, continues to be used in 4G and 5G networks and is also known for inherent vulnerabilities. GTP lacks robust, built-in security mechanisms. These inherent vulnerabilities make it a potential hotbed for security exploits through the IPX/GRX border, like - Denial of Service, Data interception, Fraud, Subscriber impersonation and Data disclosure. Despite some upgrades and changes, these vulnerabilities are carried forward, posing a significant threat to the security and reliability of 5G networks.
TSG GTP Firewall is a high-end security solution built to shield mobile networks from potential risks associated with GTP. This Firewall, a vital part of our Telecom Security Guard (TSG) platform, provides robust security for 3G, 4G, and 5G networks, maintaining secure and seamless telecom services. Compliance being key in security, our Firewall aligns with the GSMA FS.20 guidelines, safeguarding your network from GSMA Category 1, 2, and 3 threats. Our solution’s unique feature which helps query actual subscriber location information provides protection Category 3 attacks.
Our Firewall can be used as standalone solution, and even higher efficiency is achieved by synergizing with other TSG platform modules to cross-check threats across protocols like SS7, Diameter, and HTTP/2.
The GTP Firewall can be deployed as a virtual network function of a bare metal appliance
It can act as a standalone network function or part of the full TSG platform
Both on premises and cloud deployment options are supported
