Effective Fraud Prevention for SMBs<br />

by Isaac Gurary<br />

When most people think of online credit card fraud,<br />

they imagine fraudsters targeting popular websites<br />

such as Tiffany’s, Amazon or Macy’s. While large<br />

businesses are most certainly targets for fraud,<br />

most have sophisticated in-house fraud departments that<br />

exclusively deal with fraud prevention. Those fraud prevention<br />

departments are generally well staffed with experts that have<br />

access to sophisticated fraud detection technology.<br />

When it comes to small to mid-sized businesses, most are not<br />

able to afford to employ such personnel and fraud prevention is<br />

often delegated to customer service reps, warehouse managers<br />

or simply anyone that happens to have a few extra hours that<br />

can manually review certain orders.<br />

The latest LexisNexis True Cost of Fraud Report (<strong>2016</strong>) states that<br />

the average small to mid-sized eCommerce business receives<br />

353 fraud attempts monthly, of which 114 are successful. This<br />

obviously comes at great cost to eCommerce merchants, so<br />

many have implemented basic fraud prevention strategies to<br />

help mitigate this risk.<br />

What are some of these strategies that SMBs are currently using<br />

for fraud prevention?<br />

1. Usage of Gateway Fraud Filters: Most Gateways allow<br />

the eCommerce merchant to set up some basic rules to<br />

block transactions that may be fraudulent. An example of<br />

that is when there is an AVS mismatch they can decline the<br />

transaction. This is generally the first line of defense used<br />

by SMBs and can work decently for businesses that are<br />

not high fraud targets. This is not a great solution for most<br />

eCommerce businesses as the selection of available rules<br />

is pretty sparse and the available rule set capabilities are<br />

not very flexible, leading to a higher rate of false positives<br />

(blocking a legitimate transaction due to overzealous fraud<br />

prevention efforts). The technology utilized is also pretty<br />

basic so the potential to block all fraudulent transactions is<br />

limited as well.<br />

2. Manual Review: Many eCommerce merchants will have<br />

employees that will review purchases over a certain<br />

dollar amount to confirm their legitimacy. Currently, the<br />

average eCommerce merchant manually reviews 26%<br />

of all transactions*. The manual reviews typically involve<br />

using search engines such as Google to find any mentions<br />

of the purchaser’s name or other credentials, tracking<br />

the purchaser’s social media accounts, and using online<br />

maps, often with street views to make a best estimate if<br />

transaction on their website was made by the cardholder.<br />

While this is a definitely improvement for using gateway<br />

filters exclusively and manually reviewing orders does catch<br />

a lot of obvious fraud, there are still quite a few downsides<br />

to this method:<br />

a<br />

The employee(s) doing the manual review would need to be<br />

up to date with all the latest fraud tactics - any knowledge<br />

gap can be very costly.
