Free Scoping CallTelecommunications Vulnerability Intelligence
Telecom operators manage the backbone of digital connectivity. Compromised telecom infrastructure enables mass surveillance, call interception, and disruption of emergency services.
SS7/Diameter Protocol Exploitation
Legacy signaling protocol vulnerabilities enabling call interception, SMS redirection, location tracking, and two-factor authentication bypass across the global telecom network.
5G Network Slicing Isolation Failures
Insufficient isolation between 5G network slices allowing cross-slice data leakage, resource exhaustion, and unauthorized access to enterprise-dedicated network segments.
SIM Swapping and eSIM Hijacking
Social engineering and API exploitation enabling unauthorized SIM profile transfers, account takeover, and interception of SMS-based authentication codes.

Frequently Asked Questions
How is the API Security Testing schedule determined?
After a preliminary analysis where we map all targets, we calculate the man-day effort and present a finalized schedule.
Do you help remediate the vulnerabilities?
Absolutely. Our report includes specific remediation advice tailored to your tech stack and infrastructure.
Are reports valid as legal compliance documents?
Prepared using globally recognized methodologies (OWASP, NIST), our reports act as formal reference documents for auditors.
