Enea Adaptive Signaling Firewall
Intelligence-Driven Signaling Firewall for All Network Generations
Mobile network operators use the Adaptive Signaling Firewall to protect 2G, 3G, 4G, and 5G networks from signaling threats such as location tracking, reconnaissance, denial-of-service attacks, interception, and privacy leaks. Powered by patented detection techniques and comprehensive signaling threat intelligence, it delivers proactive protection against complex attacks and emerging threats on SS7, Diameter, GTP-C, and HTTP/2.
36
Deployed and actively protecting networks in 36 countries on five continents.
100%
Successfully defended against 100% of attacks in rigorous customer network testing.
Protecting Networks, Users, and Compliance
The Adaptive Signaling Firewall is designed as a long-term security foundation for mobile network operators. The need for signaling security evolves continuously as networks expand, technologies change, and attacker techniques advance. Enea partners with operators to stay ahead of that evolution.
Signaling Security Expertise Built In
As an active member of the GSMA’s Fraud and Security Group, Enea contributes to signaling security standards and best practices, bringing deep, real-world expertise in SS7, Diameter, GTP-C, and 5G signaling directly into the Adaptive Signaling Firewall. This ensures protection remains effective across all network generations.
Powered by Real-World Threat Intelligence
The signaling firewall is enhanced with global threat intelligence derived from real-world attacks observed across networks worldwide. These insights are continuously translated into actionable protections, enabling operators to defend against both known and emerging threats, even before they are seen locally.
Adaptive to Any Network, Any Compliance Need
Built for adaptability, the Adaptive Signaling Firewall meets diverse regulatory and compliance obligations across regions. It supports multi-generation networks, non-disruptive updates, and flexible deployment models aligned with operators’ cloud and infrastructure strategies.
Features and Benefits
Built by Signaling Security Experts
Developed by the experts who help define industry best practices, the Adaptive Signaling Firewall is backed by Enea’s long-standing leadership in signaling security research. Our team who contributes to some of the most influential GSMA signaling security policies, also ensures that real-world threat expertise is engineered directly into the firewall.
Powered by Global Threat Intelligence
The firewall is powered by comprehensive, proactive signaling threat intelligence that delivers deep visibility into both current and emerging attack techniques, ensuring effective protection even against previously unseen threats.
Protection Across All Network Generations
The Adaptive Signaling Firewall secures SS7, Diameter, GTP-C, HTTP/2, SIP, and ISUP with true real-time, cross-protocol correlation. A single firewall protecting all network generations increases security effectiveness while simplifying operations, management, and maintenance.
Unified Platform for Signaling, Voice, and Messaging
Sharing a common platform with the Adaptive Voice Firewall and Adaptive Messaging Firewall improves operational efficiency, reduces total cost of ownership, and minimizes reliance on specialized in-house expertise.
Faster Response to New Threats
Security updates and enhancements can be applied through configuration changes without service interruption or maintenance windows. This allows operators to deploy new protections in minutes rather than waiting months for updates.
Flexible Deployment Options
The Adaptive Signaling Firewall supports deployment across public, private, and hybrid clouds, virtualized environments, and bare-metal servers. This flexibility allows operators to deploy on today’s infrastructure while remaining fully prepared for future cloud migrations or architectural changes.
5G-Ready by Design
5G signaling requires the same level of protection as legacy networks. Rather than treating 5G security in isolation, the Adaptive Signaling Firewall integrates protection across all signaling protocols, safeguarding modern 5G networks against legacy, hybrid, and emerging threats.
Standards-Compliant and Beyond
The Adaptive Signaling Firewall complies with GSMA FS.07, FS.11, FS.19, FS.20, FS.36, and IR.82, fully addressing GSMA Category 1, 2, and 3 security recommendations. Beyond compliance, it applies advanced behavioral and protocol-level analysis to detect emerging and previously unknown threats.
Patented Category-3 Protection
Patented algorithms detect sophisticated malicious signaling that mimics legitimate roaming subscribers—raising the bar for advanced attack prevention. Detailed location and movement analysis further enhances protection in sensitive or geographically complex environments, including border regions, maritime networks, and satellite use cases.
Expertly Managed
Signaling security expertise is scarce. Enea offers managed services for its firewalls, enabling operators to leverage Enea’s deep signaling security expertise and global threat landscape insights to keep defenses continuously up to date. For operators with the required skills and resources, the firewall can also be managed in-house, providing flexibility without compromising security.
