Case Study: Orrstown Bank achieves a 50% reduction in fraud losses and enhanced security and business intelligence with Splunk Cloud (Splunk)

Orrstown Bank Invests in Splunk Cloud for Security and Business Intelligence

Orrstown Bank, a $1.2 billion community bank with 22 branches in Pennsylvania and Maryland, faced rising debit-card fraud and strict regulatory requirements but lacked the visibility and analytics from its one-size-fits-all SIEM. The bank needed a cloud-first solution to detect internal and external threats, collect forensic evidence, and minimize on‑premises infrastructure while improving operational efficiency and customer experience.

Orrstown deployed Splunk Cloud in two weeks, aggregating data from 60+ sources (ATMs, transaction histories, firewalls, servers, etc.) and adding anomaly-detection and real-time dashboards for centralized security and business analytics. The result: faster detection and response, an estimated 50% reduction in fraud losses, improved ATM performance and customer satisfaction, lower administrative overhead, and the ability to meet compliance mandates.
