Case Study: Global Telecommunications Provider achieves real-time third-party connection visibility and avoids potential PCI fines with ExtraHop

Global Telco Provider Improves Compliance and Security with RevealX

A global telecommunications provider serving tens of millions of customers and working with over 30,000 third‑party vendors needed real‑time visibility into external connections to ensure security, compliance, and performance. Their manual CMDB was quickly outdated—an audit uncovered more than 650 devices not registered in the CMDB, and a vendor was transmitting PII over unencrypted Telnet, creating a risk of PCI violations and data breaches.

By using ExtraHop’s network performance and security analytics, the telco gained automatic, real‑time discovery and CMDB updates, independent monitoring of third‑party connections, and rapid detection and remediation of unencrypted traffic. The solution exposed and closed hidden risks, halted insecure data flows, and helped the company avoid potential PCI fines worth millions.
