As 5G expands and merges with existing 4G networks, the signaling layer becomes a prime target for sophisticated attacks. Next-generation signaling firewalls (NGFWs) provide real-time threat detection, protocol correlation, and advanced analytics to secure the signaling perimeter across SS7, Diameter, GTP, and 5G core interfaces.

In today’s hybrid 5G and 4G environment, signaling threats are more complex and widespread driven by the convergence of cloud, IoT, and data layers. Next-generation signaling firewalls (NGFWs) play a vital role in defending networks by scanning, inspecting, and verifying signaling traffic before it reaches the core. These firewalls provide comprehensive visibility and advanced threat intelligence to detect anomalies and cross-protocol attacks across SS7, Diameter, GTP, and emerging 5G interfaces like HTTP/2 and PFCP. With real-time blocking, protocol correlation, and control over policies, NGFWs ensure telecom networks remain resilient, secure, and future-proof.
