We were using a tailored version of the solution built for us by Forter. If we needed to use new parameters, they'd upgrade for us. The solution is used for credit card purchases. You insert your card number, your address, and other details. Underneath, the system takes your IP, your connection details related to the browser, and whether you've connected from a tablet, phone, etc. All that information goes to Forter and enables us to know whether the user is trying to commit fraud. We are customers of Forter and I'm the lead developer.
