PayPal’s Fraud Protection Services, in conjunction with your Payflow service’s standard security tools such as Account Monitoring, can help you reduce fraudulent online transactions for which you would usually be liable. PayPal’s Fraud Protection Services automatically screens (filters) transactions for known or suspected fraudulent identifiers, allowing you to accept, reject, or hold for review transactions that include these high risk triggers.
PayPal's Fraud Protection Service contains the basic fraud filters:
Total Purchase Price Ceiling Filter
Total Item Ceiling Filter
Shipping/Billing Mismatch Filter
AVS Failure Filter
CSC Failure Filter
ZIP Risk List Match Filter
Freight Forwarder Risk List Match Filter
IP Address Velocity Filter
You also have the option of adding Buyer Authentication and Account Monitoring. PayPal’s Buyer Authentication Service integrates Visa’s Verified by Visa and MasterCard’s SecureCode into secure calls to the PayPal-hosted Payflow service. These services prompt buyers to provide a password to their card issuer before being allowed to execute a credit card purchase. Using Buyer Authentication shifts fraud liability from the merchant. PayPal's Account Monitoring includes:
Transaction monitoring by trained PayPal security professionals who identify fraudulent activity prior to settlement.
Proactive notification of suspicious account events.
A call-in number to speak with security representative about suspicious account activity and understand how to take proactive measures to prevent in future.
Complete investigation and research of suspicious account events, including:
Investigation of PayPal Internet log files and audit trails relevant to your account
Packaging of all relevant data to assist in funds recovery process with bank, and prosecution with law enforcement
