Case Study: Large US-Based ISP achieves cost savings and new managed DDoS revenue with NETSCOUT Arbor Sightline & TMS

ISP’s DDoS Mitigation and Reporting Cuts Costs and Provides Revenue via Managed DDoS Services

A large US ISP was seeing very large DDoS attacks that overwhelmed edge and near‑edge equipment, causing regional outages and making detection and forensic investigation slow and costly. Existing monitoring tools focused on performance, leading to unnecessary truck rolls and leaving many customers unable to protect themselves; the ISP needed a faster way to detect and block attacks, reduce operational costs, and offer managed DDoS protection.

By deploying NETSCOUT Arbor solutions—Sightline with Sentinel, Threat Mitigation System (TMS), Arbor Edge Defense and Arbor Cloud—the ISP gained rapid detection, automated orchestration (including BGP FlowSpec and on‑edge scrubbing), and detailed reporting of what traffic was blocked, where and why. The outcome was faster time to resolution, lower operational overhead and fewer truck rolls, plus a new managed DDoS service that provides customers on‑demand or always‑on protection with transparent mitigation reporting.
