Case Study: National Government Tax Agency achieves improved service delivery, visibility, and DDoS protection with NETSCOUT

Tax Agency Capitalizes on Cisco ACI SDN Migration, Improves Service Delivery With NETSCOUT

A national tax agency that processes millions of returns and supports 35,000+ employees had completed a migration to a Cisco ACI SDN with 40GB links but encountered visibility gaps across the new leaf-and-spine data center fabric and faced repeated DDoS attempts that threatened public-facing tax collection services and taxpayer data.

The agency implemented a single-vendor NETSCOUT solution—nGeniusONE with InfiniStreamNG appliances, Packet Flow Switches, and Arbor Edge Defense—tapping ACI traffic, generating real‑time “smart” data, and forwarding conditioned feeds to security tools. The deployment closed visibility blind spots, enabled proactive performance management, blocked inbound DDoS attacks (and outbound malicious traffic), validated the SDN investment, and preserved continuous, secure tax service delivery.
