Case Study: Service Credit Union cuts fraud loss 70% by cracking down on account takeovers with Unit21
Key results
The challenge
Service Credit Union faced a year-over-year increase in fraud loss driven by account takeovers, with as many as 10-20 successful ATOs daily leading to losses upwards of millions per quarter. Its legacy system only generated alerts in nightly batches, treated internal transfers as non-threatening, and could not be customized to flag the fraud the team was seeing.
The solution
The credit union replaced its rigid legacy vendor with Unit21's flexible transaction monitoring and case management platform, gaining control over data mapping, custom rules, and alert timing.
“Just because it's a 'best-in-class' tool does not mean it's doing the job right. We could no longer rely on our vendor to protect us. We had to take charge.”

The results, in context
Service Credit Union reported a 70% reduction in fraud loss, preventing over $1M in fraud losses quarterly, with the platform detecting 50% of fraud cases first and automating 2-3 FTEs worth of manual work. The figures are documented in Unit21's Service Credit Union customer story.
