Protect Yourself with the Authorize.net Velocity Filter

eCommerce merchants are vulnerable to a certain type of fraud that is perpetrated by attempts to authorize stolen credit card numbers via a program that generates hundreds or even thousands of credit card authorizations at one time. We saw a recent case that resulted in over 8,000 such attempts in one day! You may not realize this is happening until you check your daily batch, or worse, not catch it until the month end statements show the excessive transaction fees being charged for these authorizations. Please protect yourself by using the fraud filters available with your eCommerce software. If you use the Authorize.Net payment gateway, please enable the Velocity Filter, which limits the number of transactions allowed per day. To set that filter, go to the “Account” menu, and click on the “Daily Velocity” link under the Security Settings area. Authorize.net also has additional Fraud Screening technology available with their optional Advanced Fraud Detection Suite.

In addition to setting these filters, we strongly recommend that you review your transaction activity every day before the settlement time, and immediately contact us or the 24/7 support center if you see any anomalies. This type of fraud can quickly add up to thousands of dollars in authorization fees, and we don’t want to see that happen to any of you!
