ABOUT_US
A dedicated team of telecommunications security researchers, engineers, and analysts — specialized in identifying, analyzing, and mitigating vulnerabilities across all generations of cellular networks.
TelcoSec specializes in identifying, analyzing, and mitigating vulnerabilities across all generations of cellular networks (2G, 3G, 4G LTE, and 5G). Through advanced tooling, rigorous security audits, and continuous protocol research, we empower network operators, equipment vendors, and enterprises to build resilient, attack-proof telecommunications infrastructure.
Our core research teams operate across baseband exploitation, SS7/Diameter signaling analysis, 5G core architecture, and radio access network security — providing the most comprehensive coverage in the industry.
Cellular Stack Research
Specialized expertise in baseband firmware reverse engineering, non-access stratum (NAS) protocol analysis, and 5G SBA security models.
Vulnerability Disclosure
Systematic discovery and coordinated disclosure of critical vulnerabilities in global mobile infrastructure and roaming interconnects.
End-to-End Validation
Validation services spanning SIM/eSIM security, radio interface encryption (A5/x, SNOW 3G), and core network signaling protection.
Standardization Support
Assisting GSMA and 3GPP working groups in hardening future telecommunications standards through proactive threat modeling.
