Case Study: Major Financial Institution achieves reduced customer-portal downtime by detecting and mitigating evasive DDoS attacks with NETSCOUT Arbor Sightline & TMS

CDN’s Add-On DDoS Protection Falls Short for Major Financial Institution

One of the world’s largest financial institutions with global data centers serving millions faced repeated multi-vector, evasive DDoS attacks that slipped past its CDN’s add-on protection, rendering critical customer-facing applications unavailable for hours and exposing the limits of a cloud-only defense.

By using NETSCOUT Arbor Sightline, the Arbor Threat Mitigation System (TMS), and the ATLAS Intelligence Feed, the customer gained full edge visibility to detect attacks the CDN missed and forward them to TMS for mitigation. This hybrid, multi-layered solution identified and stopped attacks designed to evade upstream protections, significantly reducing downtime of a critical portal and preventing recurring, customer-impacting outages.
