How Global Fraud Protection Works for You 

Our Global Fraud Protection helps detect and block fraud by using machine learning that examines data across billions of global transactions. It's built right into your website and requires no work on your part. 

By learning from billions of sales each year, our global fraud protection assigns a risk score to each transaction and automatically blocks high-risk charges before they ever hit your business. 

Fraud Protection Details 

• Partnerships with Visa, Mastercard, American Express, and others allow us to use data like TC40s, SAFE reports, and early dispute notifications to identify fraudulent activity. 

• Proxy detection is used to identify IP spoofing and proxy usage, both of which are leading indications of fraud.  

• We also use the customer's email domain to determine if a payment is fraudulent. 

• With billions of transactions happening through our network every year, we can use historical card data to spot patterns across years of data. 

• We also use more standard fraud detection methods like customer detail matching to ensure that the billing, shipping, and other properties match the customer information.  

• Taking this a step further, we can use a customer's data to track the number of distinct countries in which the card was used during the past day. For example: The system sees a card registered in Canada having been used in three or more countries in the past twenty-four hours and assigns a level of fraud probability, then handles it accordingly. 

Additional Information

• For the most part we block fraud before you ever sees it or know it’s getting blocked. Sometimes transactions get through or we’re not 100% sure it is fraud. In these scenarios we proactively email the you and inform you of the risk.
• If a you suspects a transaction may be fraudulent, please contact our support teams, from there they will open a case with our Risk Team for additional assistance or advice on how to handle the transaction.
• At times you may also see in-store transactions get declined for fraud. This usually has an error code of something like ‘Declined. Suspected Fraud’. When this happens, it means one of our risk rules have been triggered and/or we received information from the card issuer about that card. In some cases, the merchant may still want to accept such transactions, while it is technically possible, we strongly discourage that behavior since it introduces additional risk to us and the merchant.
