Case Study: Leading Financial Institution reduces MTTR and streamlines SOC workflows with NETSCOUT Omnis Cyber Intelligence and Splunk

Enhancing Bank Security with Splunk and NETSCOUT’s Omnis Cyber Intelligence

A global leader in banking with branches across six continents and trillions of annual transactions faced a persistent cybersecurity challenge: siloed alerts and a fragmented workflow left SOC analysts unable to quickly correlate endpoint detections with the underlying network activity. Despite heavy investments in security tools, the bank’s analysts spent excessive time digging through logs, leading to delayed responses and elevated MTTR.

The bank deployed Splunk Enterprise with a custom Tier 1 dashboard and integrated NETSCOUT’s Omnis Cyber Intelligence (OCI) to combine EDR alerts with deep packet–level network context. Analysts could pivot from Splunk to OCI to trace ingress vectors, extract suspicious file hashes, and then search enterprise-wide for other compromises; automation also reduced ticketing errors. The result: MTTR fell from hours or days to minutes, analyst workflows became more intuitive, additional infected systems were identified faster, and overall confidence in the bank’s cybersecurity posture improved.
