Case Study: Travel Company achieves PCI compliance and 75% faster incident resolution with Sumo Logic

Travel Company - Customer Case Study

A global, multi‑billion‑dollar travel company that powers a high‑volume bookings engine was struggling with exponential log growth — processing over 5 billion web requests per month and generating roughly 50 GB of daily logs across 250 AWS EC2 instances. Manual Syslog-based monitoring couldn’t scale or provide searchable, actionable intelligence, and meeting PCI DSS Requirement 10 (tracking and monitoring access to cardholder data) became increasingly difficult and time‑consuming.

The company chose Sumo Logic for its rapid time‑to‑value, low management overhead, robust feature set and strong security posture (including PCI DSS 3.0 Service Provider Level 1 and encryption in transit and at rest). That decision reduced the time, cost and complexity of PCI audits, extended analytics to IT Ops and development, and cut mean time to investigate and resolve incidents by more than 75%, dramatically speeding problem detection and remediation.
