Case Study: DNSimple achieves zero false positives and 90% fewer chargebacks with Sift

How DNSimple completely eliminated false positives using Sift

DNSimple, a domain registration and DNS management service with thousands of customers, struggled with card-testing and phishing fraud that produced frequent chargebacks. Lacking proactive defenses and only having a five-day window to identify fraudulent transactions, the company was forced into slow, reactive investigations that couldn’t stop ongoing abuse.

By quickly integrating Sift (initial JavaScript install and a short REST API rollout), DNSimple used Sift Scores and Network Visualizations to prioritize reviews, expose linked fraud, and streamline investigation workflows. The result: chargebacks dropped by over 90%, they report zero false positives, faster reviews, and no negative impact on legitimate customers.
