Case Study: Wireless Telecommunications Company achieves real-time visibility into third-party connections to improve security and compliance with ExtraHop

Global Telecommunications Provider Uses ExtraHop to Monitor External Connections to Improve Compliance and Security

A global telecommunications provider serving tens of millions of customers depends on more than 30,000 third‑party vendors to maintain its services. The company faced a critical visibility gap: its CMDB was manually maintained and quickly became outdated, and a routine audit revealed hundreds of vendor‑connected systems that weren’t tracked, creating security, compliance, and performance risks.

By leveraging ExtraHop’s real‑time network performance and security analytics, the telco automatically discovered and populated device and connection details into the CMDB, eliminating the blind spot. The deployment uncovered 650+ unregistered machines, detected a vendor transmitting PII over unencrypted Telnet (averting potential PCI fines worth millions), halted insecure traffic, and gave the security team independent, continuous visibility into third‑party connections.
