Secure Your Signaling Network. Protect Subscriber Trust.
Comprehensively assess and secure the protocols that power communication across modern and legacy mobile networks—ensuring resilient control-plane operations and protected subscriber data.
Signaling Security Testing provides a comprehensive evaluation of the protocols that govern communication across mobile networks. It focuses on both modern 5G service-based interfaces and legacy signaling systems to uncover vulnerabilities that can impact network integrity and subscriber privacy.
This service ensures signaling networks operate securely and reliably across 2G, 3G, 4G, and 5G environments, safeguarding both infrastructure and subscriber data.
Why It Matters
As telecom networks evolve, the coexistence of legacy and next-generation protocols increases the attack surface. Without proper assessment, vulnerabilities within signaling layers can compromise control-plane communications and expose critical services.
Hidden Risks Across Signaling Layers
Signaling protocols are foundational to mobile network communication—but also present critical security risks when not properly secured. Both legacy and modern signaling interfaces require continuous evaluation to mitigate these risks effectively.
Subscriber Tracking
Exploitation of signaling data to monitor user location.
Call & SMS Interception
Unauthorized access to communication channels.
Denial-of-Service (DoS)
Disruption of network availability.
Network-Wide Disruptions
Exploiting protocol weaknesses to impact services at scale.
Comprehensive Multi-Protocol Assessment
We cover the full spectrum of signaling protocols, from legacy SS7 to modern 5G HTTP/2 interfaces.
HTTP/2
5G Service-Based Architecture
What it is?
Underpins communication in 5G service-based architecture, enabling API-driven interactions between network functions.
Why it is vulnerable?
As an API-based protocol, it introduces risks related to insecure communication, message tampering, and insufficient encryption.
What we assess?
