Case Study: International Bank achieves rapid identification of months-long payment gateway slowdowns with NETSCOUT

NETSCOUT Pinpoints Source of Months-long Slowdown in Custom Payment Gateway App

An international bank with dozens of branches and 100+ ATMs faced months-long intermittent latency in its custom payment gateway, causing transactions to time out, frustrate customers and staff, and trigger blame between the bank and third-party providers. The IT team lacked end-to-end observability and packet-level evidence to identify where delays originated, making troubleshooting slow and inconclusive.

By deploying NETSCOUT’s nGeniusONE, InfiniStreamNG appliances and packet flow switching, the bank gained hop-by-hop visibility, custom application identification, and deep packet inspection at microsecond granularity. That evidence quickly pinpointed the third-party payment processor as the source of the slowdowns, enabling remediation, ending the “blame game,” and improving troubleshooting efficiency and the bank’s digital customer experience.
