Case Study: Cyber Resilience in Telecommunications

How a Telecom Provider Secured Network Infrastructure, Protected Customer Data, and Reduced Cyber Insurance Premiums by 58%

Industry Example: Telecommunications & Network Services
Company Size: ~1,000 employees across multiple regional offices and network operations centers
Annual Revenue: US $650 million
Estimated Cyber Insurance Premium (Before): US $950,000/year
Estimated Cyber Insurance Premium (After): US $399,000/year
Savings: ~58% reduction through validated security controls and continuous monitoring

The Challenge

A leading telecommunications provider faced growing cybersecurity risks as customer data, network infrastructure, and cloud-based services expanded.

Key challenges included:

  • Customer data protection: Personal, billing, and usage data for millions of customers needed robust protection against theft or leakage.

  • Operational risk: Network outages, compromised routers, and service disruptions could impact millions of users and result in regulatory penalties.

  • Complex IT environment: Distributed network operations centers, remote staff, and third-party vendor access increased exposure.

  • Rising insurance premiums: Insurers demanded evidence of continuous control validation and cyber maturity for coverage renewal.

Without a structured cyber assurance program, the provider risked data breaches, network downtime, regulatory fines, and rising insurance costs.

The Solution

The telecom company implemented a cyber assurance and control validation platform, following the Antigen Security methodology, tailored to large-scale telecommunications operations.

Key initiatives included:

  • Continuous Control Validation: Automated verification of endpoint protection, MFA, patching, and access controls across offices, NOCs, and network devices.

  • Network & Infrastructure Security: Real-time monitoring of routers, switches, and core network systems for misconfigurations, vulnerabilities, and unauthorized access.

  • Customer Data Protection: Oversight of billing systems, CRM platforms, and cloud storage for sensitive customer information.

  • Third-Party Risk Management: Continuous scanning of vendor portals, cloud providers, and service partners with access to critical infrastructure.

  • Insurer-Ready Reporting: Consolidated cyber posture and risk scorecards mapped to ISO 27001, SOC 2, and NIST CSF standards for insurers and regulators.

The Outcome

Rapid Risk Reduction
Within 45 days, the platform identified and helped remediate:

  • Misconfigured network devices exposing internal management interfaces

  • Outdated patches on NOC workstations and network servers

  • Shared credentials and weak passwords across regional offices

Quantifiable Results:

  • Cyber control compliance improved from 69% to 97% across all systems and offices

  • Cyber insurance premiums reduced by 58%, with expanded coverage for network downtime, data breaches, and ransomware

  • $551,000 in annual premium savings

  • Zero major cyber incidents affecting network operations in the following 12 months

Operational and Strategic Benefits:

  • Simplified compliance reporting for SOC 2, ISO 27001, and regulatory audits

  • Reduced manual monitoring and IT oversight by 65%

  • Enhanced visibility and security of distributed network infrastructure

  • Strengthened trust with customers, partners, and insurers

Why It Matters for the Telecommunications Industry

Telecom providers manage critical infrastructure and highly sensitive customer data, making them prime targets for cyberattacks. Common risks include:

  • Network outages caused by ransomware or misconfiguration

  • Data breaches impacting millions of customers

  • Insider threats and third-party vendor vulnerabilities

  • Rising insurer expectations for verified cyber maturity

By implementing continuous control validation, monitoring, and insurer-ready reporting, telecom companies can:

  • ✅ Protect customer data and critical network infrastructure

  • ✅ Reduce cyber insurance costs and expand coverage

  • ✅ Prevent operational disruption and downtime

  • ✅ Demonstrate cyber resilience to insurers, regulators, and partners

  • ✅ Strengthen customer trust and competitive positioning
