Blocking high risk transactions

[hk123]

Hi all,

Our web store was hit by series of fraudulent transactions for the past few months and we now plan to have a simple fraud check at the lowest cost if possible. We checked the IPs and most of the transactions were from Nigeria and China. We have contacted some freelancers on developing such feature for us but the setup fee seems like not cheap. Where can I find third party tools to monitor fraud transactions?(Perhaps free one? 😃) Thanks.

What do you mean by "fraud check"? How are you processing your transactions now (paypal, a bank payment gateway, other)? What kind of fraud are we talking about?

As far as "cheap" goes, I would not recommend choosing a solution based on cost. The "cheap" guy might be cheap for a reason - and your potential losses/ liability can easily outweigh what it would cost to implement a good solution.

The solution to the problem of fraud depends on how the fraud was perpetrated. If your site has some exploitable logical flaw, you'll need to fix it. If your business has some exploitable business process (like mailing your products to consumers before they pay for it) then you need to examine that. Your payment gateway (e.g., paypal or authorize.net) may have certain features you can use to improve the quality of your site's validation -- things like enforcing address matches and collecting the 3-digit security code, etc.

Thanks for all of the replies.
We manage to find several solutions from maxmind, fraudlabs pro and subuno. Seems like we still need freelancers to help us integrate with their tool. In the process of evaluation. :o
