Case Study: Northumbrian Water maintains always-on VoIP and Citrix availability for 4.4M customers with NETSCOUT nGenius

NetScout Assures Network Applications Always On Tap for Northumbrian Water

Northumbrian Water Limited (NWL) is a major UK water and wastewater utility serving 4.4 million customers and 2,000 corporate users across three data centers and more than 50 WAN links. With critical Citrix and VoIP applications running over a geographically dispersed, multi‑vendor network, NWL needed better, continuous visibility to meet regulatory service levels and quickly identify problems that previous packet probes could not reliably detect.

NWL deployed NetScout’s nGenius solution with InfiniStream appliances at its data centers to capture, store and analyze edge traffic continuously. The unified platform verifies QoS for VoIP and Citrix, exposes misconfigurations, speeds root‑cause diagnosis, reduces service disruptions, and boosts IT productivity — helping NWL maintain high customer service and support its award‑winning sustainability commitments.
