Case Study: Large European Financial Institution achieves continuous DDoS protection and zero downtime with NETSCOUT's Arbor Edge Defense (AED) and Managed AED

Large European Financial Institution Employs Managed AED to Protect Their Networks, Applications and Services

A large European financial institution faced repeated service outages during business hours after software updates from their DDoS protection vendor, prompting an RFP for an always‑on cloud‑only solution. NETSCOUT discovered the customer’s concern that cloud monitoring alone could leave brief windows of unmitigated traffic and argued for a more resilient approach.

NETSCOUT implemented a hybrid defense: Arbor Edge Defense (AED) appliances on‑premise for always‑on, always‑mitigating protection with the chosen cloud scrubbing service as overflow, and provided managed‑AED services. A proof of concept showed AED stopped illegitimate traffic faster than the cloud alone; since deployment and fine‑tuning by NETSCOUT’s managed‑services team the institution has experienced no DDoS‑related downtime and increased confidence in network availability.
