Fraud Control

The app is useful if you take the time to understand and configure the rules correctly. Managing the messaging shown to customers when a checkout is blocked is important, as the default language is too soft for effective deterrence.

One major drawback is the lack of visibility into who is actually being blocked at checkout. All blocked users remain anonymous, so you only see aggregate counts rather than actionable detail. Greater transparency here would significantly improve the product.

Lastly, you can edit what the blocked customer sees by searching the language for "Decision rule block"

I was a little confused by the poor reviews, but they were completely unfounded.
After installing the app, the “Fraud Control” app appears on the left in the admin menu. And right below it is Rules. So it's not a button, but a menu item. You can then create rules there.

A bot is using my store to test stolen credit cards. I contacted Shopify support about it and they said to install this app and it'll help to stop the attacks. Well, this app does nothing to stop the attacks from happening. I'm still getting hundreds of abandoned carts with card details and fraudulent orders are still getting through.
