Advanced fraud detection and prevention tools for online payments
The Advanced Fraud Detection Suite (AFDS) gives merchants built-in fraud detection tools to screen online payments, flag suspicious transactions, and review risky orders with rules-based controls inside the payment gateway.
eCommerce fraud doesn't just target big businesses
Over the next five years, analysts project that small and medium businesses will face more than $130 billion in losses from payments fraud,1 yet most SMB owners believe they're too small to be targeted. That's exactly what fraudsters count on.
Authorize.net's fraud detection tools are built specifically for businesses of your size: no security team required, no complex integration, just 13 configurable filters that work from day one.

Three layers of payment gateway fraud prevention
Effective payment gateway fraud prevention works at three levels: your own business practices, your payment gateway's built-in tools, and your network firewall. Authorize.net handles the middle layer automatically. Here’s how you can strengthen all three areas.
Be proactive
Look at your website and see where you might be vulnerable. What customer verification tools do you have in place now? Don’t ignore suspicious activity.
Use a fraud prevention tool
AFDS is the built-in eCommerce fraud prevention service included with every plan. Its 13 configurable fraud filters let you set transaction thresholds, payment velocity limits, IP address blocks, country restrictions, and more. Every filter triggers a specific action you control: hold for review, decline automatically, or process and flag.
Set up a simple firewall
Many firewalls come with basic tools for botnet detection, prevention, and removal.
What Authorize.net's fraud detection software monitors
AFDS screens every transaction against 13 configurable filters covering the most common vectors of ecommerce fraud. Each filter operates independently, so you can tune your protection to match your specific business risk profile.
Transaction amount thresholds
Block or flag orders that fall outside your typical order value range, catching both unusually large purchases and micro-transactions used in card testing.
Payment velocity limits
Detect multiple rapid transactions from the same card, email, or IP address, a common pattern in automated fraud attacks.
Shipping and billing address mismatches
Flag orders where the shipping destination doesn't match the card's billing address.
Country and IP address restrictions
Block or review transactions originating from specific countries or regions outside your customer base.
Suspicious customer data patterns
Identify repeated use of the same email, phone number, or device across multiple failed or flagged transactions.
Support every major card your customers use
Authorize.net accepts all major credit and debit cards, including Visa, Mastercard, American Express, Discover, JCB, and UnionPay. Whether your customers pay with a signature debit card, a prepaid card, or an EMV chip card, your checkout stays seamless.
All card types are processed through the same secure gateway, no separate setup required per card network. Call us at 1-888-323-4289 with your questions.
