Case Study: a largest longstanding banking institution cuts troubleshooting from 2 weeks to 15 minutes with NETSCOUT observability

NETSCOUT Observability Cuts Bank’s Troubleshooting from 2 Weeks to 15 Minutes

A major longstanding banking institution faced significant IT performance challenges across its global operations. The bank's complex infrastructure, spanning multiple data centers and cloud environments, suffered from persistent issues that severely impacted user experience and productivity. Key problems included poor-quality Microsoft Teams calls causing communication breakdowns, slow LDAP authentication that halted employee logins for weeks, and call quality degradations in high-traffic contact centers. The lengthy troubleshooting processes were incurring risks to revenue and customer satisfaction, prompting the need for a solution from vendor NETSCOUT.

NETSCOUT implemented its nGenius Enterprise Performance Management solution, including nGeniusONE, InfiniStreamNG, and vSTREAM appliances, along with its Visibility as a Service (VaaS) support. This provided deep packet inspection at scale and end-to-end observability, allowing the IT team to swiftly identify root causes. Most notably, NETSCOUT's solution slashed the time to resolve the persistent LDAP server issue from two weeks down to just fifteen minutes. The bank also restored UC&C call quality and optimized contact center operations, dramatically reducing mean time to repair and safeguarding both revenue and its brand reputation.
