Case Study: PostFinance achieves improved fraud detection and enhanced customer experience with Splunk Enterprise

PostFinance Delivers Improved Fraud Detection and Enhances Customer Experience

PostFinance, Switzerland’s third-largest retail bank with nearly three million customers and the country’s leading payments provider, needed better visibility into payments processing and its online banking platform to proactively detect and respond to fraud and phishing threats. Existing processes were manual and fragmented, limiting the bank’s ability to spot anomalies across merchant transactions and its E‑Finance portal used by 1.6 million customers.

By deploying Splunk Enterprise to monitor e‑commerce, web and middleware logs, reverse proxies and banking systems, PostFinance automated about 50 fraud searches into dashboards and real‑time workflows. The result: faster, more accurate debit‑card and online fraud detection, streamlined investigation and escalation, improved response to phishing attacks, and new merchant insights that help product teams innovate and enhance customer protection.
