Case Study: Firstmark Credit Union achieves real-time user activity monitoring and rapid incident response with LogRhythm

Firstmark Credit Union Uses LogRhythm to Monitor Internal Activities

Firstmark Credit Union, a San Antonio financial cooperative with 14 branches and over $820M in assets, needed better visibility into internal user activity to prevent theft, fraud and data breaches. Individual events on their network often looked benign alone, so the credit union required centralized log collection and event correlation across headquarters and branches to detect suspicious patterns and meet regulatory requirements.

They deployed a LogRhythm XM all‑in‑one SIEM for log and event management, advanced correlation, real‑time user monitoring (tails), file integrity checks, alerting and fast reporting. The solution delivered immediate alerts (e.g., prohibited USB use), one‑click drilldowns, rapid investigations and quick compliance-ready reports, significantly reducing investigation time and prompting plans to expand agents to every PC.
