Telecommunications

Security, Continuity and Sovereignty of Communication Infrastructure

Your operator and ISP organizations simultaneously manage BTK Information Security Regulations, ISO 27011 and GSMA frameworks alongside signaling attacks against the 5G core network and data breaches that could affect millions of subscribers. With attack-oriented EPC/5GC penetration tests, External Attack Surface Management (EASM) and signaling protocol analysis, we prevent subscriber data leakage before it happens and deliver ready evidence sets for BTK audits.

Get in Touch All Solutions

Audit & Compliance: Our telecommunications solutions are aligned with the BTK (Turkish Information & Communication Technologies Authority) Regulation on Processing Personal Data and Privacy Protection in the Electronic Communications Sector, BTK Information Systems Management regulations, ISO/IEC 27011 (telecom), ISO 27001, ETSI standards, KVKK and GDPR.

Industry Capabilities

What we do for the Telecommunications sector

Solutions designed for your sector's specific regulations, threat model and operational needs.

5G Core

Core Network and 5G Security Audit

Security validation at every layer of next-generation mobile networks.

  • 5G Architecture Audit: We test Network Slicing, MEC and RAN layers in adversary mode, proving the SLA security of the 5G slices you provide to your enterprise customers.
  • Signaling Protocols: We test location tracking and SMS redirection vulnerabilities over SS7, Diameter and GTP, closing subscriber privacy breaches before any BTK notification is needed.
  • Core Network Hardening: We run attack-oriented tests against management interfaces of EPC and 5GC components, neutralizing scenarios that could cause service disruption in the core network before production.

BSS OSS and subscriber data security
BSS / OSS

BSS/OSS and Subscriber Data Security

Security of operators' business and operational support systems.

  • BSS (Business Support Systems): We test your billing, subscriber management and CRM systems with authorization bypass scenarios, documenting and closing revenue leakage and subscriber manipulation risks.
  • OSS (Operational Support Systems): We replay unauthorized access scenarios in your network management and provisioning systems, closing the risk of a malicious insider disabling base stations.
  • Subscriber Privacy: We test CDR and metadata flows belonging to millions of subscribers, preventing KVKK Article 12 and BTK Personal Data Regulation sanctions with documented controls.
EASM

Large-Scale External Attack Surface (EASM)

Continuous monitoring of operators' vast IP blocks and domain names.

  • ZFPScan Integration: We continuously scan your operator IP blocks for asset-vulnerability mapping, turning your enormous attack surface into a single auditable inventory.
  • Shadow IT Detection: We report in real time test servers and forgotten services exposed outside the organization, closing entry points for data leakage and ransomware attacks within days.
  • DNS and Infrastructure Security: We test your authoritative DNS and BGP routing processes with hijack scenarios, eliminating route manipulation risks that could cause country-wide outages.

Backbone and data center security
Backbone / DC

Critical Backbone and Data Center Audit

Security of Internet Exchange Points (IXP) and main distribution networks.

  • Physical and Cyber Synergy: We perform controlled physical penetration of your main switch and data center buildings, proving card cloning and tailgating chains and making your security policy concrete.
  • DDoS Resilience: We validate your operator-level scrubbing centers with controlled load tests, backing the DDoS SLA commitments to your enterprise customers with concrete evidence.
Reporting & Deliverables

Audit-ready deliverables

Concrete deliverables provided at the conclusion of our audit and testing projects tailored to your telecom operation.

  • BTK Compliance Report: A defensible compliance report and evidence chain for audit visits, evaluating BTK Information and Communication Security Measures and ISO 27011 controls article by article.
  • 5G Core Network Pentest Report: Findings, evidence chain and operator-level recommended hardening steps from attack-oriented tests against SBA interfaces, NEF, AUSF and UDM components.
  • EASM Attack Surface Action Plan: An actionable roadmap with the external attack surface map over millions of IPs discovered via ZFPScan, prioritized findings and team/time estimates for remediation.
