Case Study: Aon achieves global network visibility and faster issue resolution with NETSCOUT nGeniusONE and nGeniusPULSE

AON’s Successful Journey to Global Network Visibility

Aon, a global professional services firm with about 50,000 colleagues in 120 countries, faced technology sprawl from rapid growth and more than 400 acquisitions. Their regional network performance hubs required consistent network, application and UCC performance, but multiple monitoring tools left IT without a single platform for global visibility — making it hard to answer basic questions about network health, issue resolution speed, and delivered performance.

Aon standardized on NETSCOUT’s suite (nGeniusONE, InfiniStreamNG, 5010 Packet Flow Switch and nGeniusPULSE) to create one packet- and synthetic-testing monitoring fabric with consolidated global dashboards. The solution replaced five disparate tools, improved cross-team collaboration, enabled 24/7 proactive testing and faster root-cause identification, and supported migrations (including VoIP) and routing fixes — delivering higher availability, quicker troubleshooting, and clearer performance metrics for decision-making.
