Case Study: Leading Telecommunications Service Providing Company reduces system compromises and accelerates threat detection with Lastline

Telecomm Giant Uses Lastline to Protect Against Advanced Threats

A major U.S. wireless telecommunications provider serving millions of customers faced mounting risk from sophisticated, email‑borne and lateral cyberthreats that its existing antivirus and email security tools missed. With high availability requirements (including Emergency 911 obligations), frequent false positives and an overwhelmed SOC, the carrier urgently needed better perimeter detection and real‑time threat intelligence to stop attacks before they caused fraud, outages or regulatory exposure.

The carrier deployed Lastline Defender across its distributed data centers in hours, integrating artifact analysis, network traffic analysis and intrusion prevention to identify malicious URLs, binaries and evasive behaviors. The solution improved email and web threat detection, reduced successful compromises and the number of investigations, accelerated response times (saving hours per day for the SOC), and enabled automated IoC distribution and firewall updates so analysts could focus on true high‑priority incidents.
