Case Study: Major Insurance Company achieves reliable, high-quality delivery of business-critical VMware and Citrix applications with NETSCOUT

Improving Reliability and Availability of Business-Critical Applications With Enhanced NETSCOUT Visibility

A leading U.S. insurer serving government employees and their families with medical, dental, vision and wellness plans—backed by a ~1,500-employee IT organization—faced critical visibility gaps in its VMware ESX and Citrix VDI environments. Those gaps prevented troubleshooting of web-based and virtualized applications (including a HIPAA gateway), led to prolonged outages and degraded remote end-user experience, and left IT unable to identify Citrix usage patterns or root causes for infrastructure brownouts.

The company expanded its existing NETSCOUT deployment—nGeniusONE with InfiniStreamNG and vSTREAM appliances on VMware—to generate contextual metadata and real-time analytics. NETSCOUT pinpointed an authentication-server CPU issue, restored application availability, provided Citrix VDI usage and performance dashboards, and added HL7 monitoring for HIPAA compliance. The result: faster problem resolution, improved customer and employee experience, elimination of additional application tools, and NETSCOUT adopted into the standard infrastructure build for future projects.
