Case Study: Multinational Bank achieves rapid DDoS mitigation and restored business continuity with NETSCOUT Arbor Cloud and AED

Multinational Bank Thwarts DDoS Attack to Repair Productivity Losses and Rescue Reputation

A multinational bank in Africa was hit by a large, sustained volumetric DDoS attack that forced the team to geo‑block traffic, cutting off customers and overloading two ISPs that lacked mitigation capabilities. The outage threatened business continuity, productivity and the bank’s reputation as the attack targeted their web services infrastructure over a high‑impact weekend.

NETSCOUT Arbor delivered emergency Arbor Cloud protection and rapidly deployed a virtual AED on a repurposed server, then configured GRE tunnels and automated cloud signaling to redirect and scrub malicious traffic. Services were restored within two days, losses were minimized, and the bank subsequently purchased multiple AED appliances and ongoing Arbor services to ensure continuous DDoS detection and mitigation.
