Dirobi

It takes some effort, not a plug and play app, however after many years of dealing with fraudsters I would say this is the best fraud filter I have had. It's well worth spending an hour or two to thoroughly set it up and understand everything, and their support was super helpful and responsive when I had trouble figuring out best settings. Great app and great service, this is a keeper for my store.

Very powerful and intuitive. Has been a great help building our Shopify revenue.
