Signaling Firewall
Intelligence-driven, multi-protocol signaling firewall for SS7, Diameter, GTP-C and 5G signaling.
Signaling Security
Intelligence-Driven Signaling Security
Signaling networks contain critical vulnerabilities that enable attackers to extract subscriber information, locate devices, intercept calls and messages, and perform DoS attacks. Vulnerabilities are present in all network generations and through interoperability between networks of different generations.
Enea’s intelligence-driven signaling security solutions discover, analyze, and protect against threats across multiple protocols, including SS7, Diameter, GTP-C, and HTTP/2.
Signaling Security Portfolio
Voice Firewall
Combat caller ID spoofing, fraud, and scams in voice channels.
Signaling Intelligence Layer
Know what is going on in your network. The Signaling Intelligence Layer provides visualized threat intelligence insights.
Threat Intelligence
Investigating signaling cyber threat events to uncover attacker tactics, techniques, and procedures. Identifying compromised networks and threat activity over time to assist security operation centers in measuring and understanding current signaling threats and risk levels.
Penetration Testing
Complete, independent pen testing services for SS7, Diameter, and GTP defences.
Threat Intelligence for National Security
Global intelligence-driven insights helps national security organizations understand the signaling threat landscape.
The Enea Difference
Many vendors follow GSMA recommendations but stop short of continuously adapting to a rapidly evolving threat landscape. Enea goes further. Leveraging our deep signaling security expertise, we proactively identify, analyze, and mitigate threats that extend beyond standard guidelines. Our customers benefit from real-world signaling threat intelligence gathered across five continents, continuously fed into our firewall to improve detection accuracy and strengthen protection.
Our approach is built on a continuous cycle:
- Observe – Our extensive global deployments give us a unique vantage point into the signaling threat landscape. We detect attacks in real time and closely track threat actors and their evolving techniques.
- Learn – Our threat intelligence team and security researchers analyze observed data to develop actionable insights into attacker tactics, techniques, and procedures across the signaling ecosystem.
- Adapt – Using these insights, we continuously refine firewall rules and configurations, ensuring protection against both known and emerging threats.
- Protect – Deployed directly within customer networks, the Adaptive Signaling Firewall safeguards signaling interfaces in real time, filtering and analyzing trillions of events.
The intelligence and expertise generated through this cycle are shared with the broader mobile ecosystem via industry organizations, most notably the GSMA Fraud and Security Group, where Enea actively contributes insights, research, and best practices.
