Case Study: Large Retail Company achieves faster PCI breach investigation and saves thousands with LogRhythm IIR Services

LogRhythm IR and Platform Expertise Saved Retailer Thousands

A large retail company suspected a credit card data breach and, per PCI requirements, engaged an external Payment Card Industry Forensic Investigator (PFI). The PFI lacked deep expertise in the retailer’s LogRhythm SIEM and planned to export/import all SIEM data—an approach that would have delayed the investigation by days and driven up expensive daily PFI fees.

LogRhythm’s IIR Services stepped in to train the PFI on searching active and backup log data, wrote optimized SecondLook searches, and implemented file-integrity monitoring for critical files. This avoided the time-consuming export/import plan, shortened the investigation, saved the retailer thousands in PFI fees, met PCI obligations, and enabled timely remediation of the threat.
