Case Study: Leading North American Bank detects insider threats and safeguards financial data with Splunk Enterprise

How Splunk Software is Used to Safeguard Financial Data

A major North American bank faced rising insider-threat risk from hundreds of contract developers and technical staff who had access to sensitive source code and customer data. Existing monitoring tools were siloed, costly to run at scale, and unable to correlate logs or automate responses, leaving the bank exposed to potential data exfiltration as contracts neared expiration.

The bank deployed Splunk Enterprise to ingest and index logs from BlueCoat, FireEye, Active Directory and other systems, creating unified dashboards and role- and contract-aware risk scores. When risk thresholds are exceeded, Splunk issues alerts and triggers automated actions (for example, enable targeted monitoring, block USB or cloud storage access, notify managers), reducing manual effort and monitoring costs while protecting intellectual property and customer financial data.
