Case Study: DQE Communications achieves full network visibility and scalable DDoS protection with NETSCOUT (Arbor Sightline & Threat Mitigation System)

DQE Communications Achieves Comprehensive Visibility into Network Traffic

DQE Communications, a leading commercial fiber‑optic provider in southwestern Pennsylvania with more than 3,247 miles of network, was facing limited visibility into its traffic as it expanded. That blind spot left the company ill-equipped to detect and defend against growing Distributed Denial of Service (DDoS) threats, prompting Director of IP Services Patrick Lazorchak to seek a robust visibility and mitigation solution.

DQE deployed Arbor Sightline for end‑to‑end network visibility and Arbor Threat Mitigation System for surgical, out‑of‑band DDoS removal (handling up to 400 Gbps). The combined solution delivered immediate ROI—Sightline provided day‑one visibility and, within six months, Threat Mitigation appliances were protecting upstream peering points—enabling faster, proactive responses, lower engineering overhead, reduced time‑to‑mitigate, and stronger protection for DQE’s infrastructure and customers.
