The Challenge
E-Commerce Plus was losing significant revenue to false declines while simultaneously suffering from promotional code abuse. Their existing fraud rules were overly aggressive, blocking legitimate customers at checkout.

- Promotional abuse rings were exploiting coupon codes across multiple accounts
- Account takeover attempts were increasing during holiday sales events
- Legacy vendor required 48-hour SLA for rule changes during peak traffic
- No ability to distinguish between returning customers and new suspicious accounts
