Pentest Reporting for Telecommunications
Secure critical communications infrastructure and subscriber data with penetration testing reports built for the unique demands of telecom networks.
Security Challenges in Telecommunications
Telecommunications providers operate the foundational infrastructure that all other industries depend on. From 5G radio access networks and core packet switching to subscriber management platforms and customer self-service portals, telecom attack surfaces are vast, complex, and high-value. Nation-state actors target telecom networks for surveillance capabilities, while financially motivated attackers pursue subscriber data, SIM-swap fraud, and toll fraud schemes that can cost carriers millions.
- Signaling protocols including SS7, Diameter, and GTP carry inherent security weaknesses that enable subscriber tracking, call interception, and fraud when exposed to untrusted network interconnections.
- 5G network slicing, edge computing deployments, and NFV/SDN infrastructure introduce software-defined attack surfaces where configuration vulnerabilities can compromise network segments serving critical customers including emergency services and government agencies.
- Regulatory requirements from bodies such as the FCC, ENISA, and national telecom authorities mandate security assessments of critical infrastructure, with growing emphasis on supply chain security following high-profile incidents involving network equipment vendors.
Penetration testing in telecom environments requires expertise spanning traditional IT security, mobile network protocols, cloud-native network functions, and physical infrastructure. Reports must address findings across these diverse technology domains while maintaining consistent risk ratings and providing remediation guidance that accounts for the carrier-grade availability requirements of production network elements where downtime directly impacts millions of subscribers and emergency services connectivity.
How Vulnsy Helps
Vulnsy provides the reporting framework telecom penetration testing engagements demand. Finding templates cover both IT-domain vulnerabilities in subscriber management portals, billing systems, and customer APIs, as well as telecom-specific issues such as SS7 filtering bypasses, GTP tunnel manipulation, and network function virtualization misconfigurations. Each template includes remediation guidance calibrated for carrier-grade environments where changes require extensive change management and testing.
Report generation produces documents structured around telecom network architecture domains: access network, core network, OSS/BSS platforms, and customer-facing systems. This segmentation helps telecom security teams route findings to the appropriate engineering groups, from radio access network teams to IT application developers, ensuring each finding reaches the team best positioned to remediate it.
- Client portals provide telecom CISOs with unified visibility across assessment findings spanning network infrastructure, subscriber-facing applications, and internal operational platforms.
- Team collaboration supports large-scale telecom assessments where network security specialists, web application testers, and mobile security experts contribute findings to a single cohesive report.
- Compliance-ready formats align with NIST CSF, ISO 27011 (telecom-specific guidance), and regional regulatory requirements, producing evidence packages suitable for regulatory audits and board-level security reporting.
