Case Study: Callcredit achieves real-time threat detection and predictive security with LogRhythm

LogRhythm Passes All Callcredit's Checks, Chosen to Underpin Data Security Best Practice

Callcredit, a UK provider of marketing and credit solutions that holds data on roughly 42 million individuals and 2.8 million businesses, faced growing difficulty protecting sensitive information and monitoring its IT estate — generating over 50 million event logs daily made identifying aberrant activity slow and resource-intensive. With regulatory obligations (PCI DSS, ISO 27001) and the need for a flexible platform that would integrate with multiple vendors and bespoke applications, Callcredit decided to replace its legacy tools with a next‑generation SIEM.

Callcredit deployed LogRhythm’s integrated log management and SIEM with Protective Monitoring and an AI correlation engine to centralize visibility and automate monitoring across the estate. The platform correlates tens of millions of logs in real time, delivers predictive alerts on anomalous behavior, speeds up incident detection and networking troubleshooting, simplifies compliance and reporting, and delivered a rapid return on investment.
