Risk Manager: Protect Your Online Business from Fraud

Our digital economy has made it easier than ever to sell online. But with this convenience comes increased risk of payment fraud, particularly for card-not-present transactions. For Australian businesses, having robust fraud prevention isn’t just nice to have, it’s essential for protecting your revenue and reputation.

Here’s how Square Risk Manager helps you stay ahead of fraudsters while keeping legitimate sales flowing smoothly.

What is Risk Manager?

Risk Manager is Square’s integrated fraud prevention tool that lives directly in your Dashboard. It uses advanced machine learning to monitor transactions across all your Square payment channels including Online Store, Payment Links, eGift Cards, Invoices, Buyer Subscriptions, Appointments and Virtual Terminal, to help detect and stop suspicious activity before it impacts your business.

Square also runs internal fraud prevention rules on all payments by default. Risk Manager is free for all sellers and adds an additional layer of protection, giving sellers more control to calibrate their risk tolerance and tailor fraud defenses to their business needs.

How Risk Manager Protects Your Business

Powered by advanced machine learning, Risk Manager analyses multiple risk signals in real time to help you proactively detect and prevent fraud before it impacts your business.

For example, an online clothing store might choose to invoke 3D Secure (which we will explore further down) for ecommerce transactions that exceed its typical order value or when billing and shipping addresses do not match. A café or restaurant may require 3D Secure for card-not-present payments that are above its average ticket size, such as prepaid group bookings or larger online orders, to help reduce the risk of chargebacks.

The right configuration depends on your business model and your risk tolerance. Some businesses may apply stricter rules to minimize chargebacks, while others may take a lighter approach to maintain a smoother checkout experience.

Strengthen Your Protection with 3D Secure

Want even stronger protection against fraud?

Another common form of fraud occurs when a stolen or compromised card is used to complete a legitimate-looking transaction, which later results in a chargeback.

3D Secure (3DS) is a powerful feature that helps protect your business from fraud chargebacks. With 3D Secure, the card issuer verifies the customer’s identity before payment completes. You may have seen this in some of your online purchases – a bank or card verification pops up requesting you to log in or sending you a one-time pin code to verify that you are in fact making the purchase. If a chargeback ever arises from a 3D Secure-verified transaction, liability shifts to the issuer, meaning you’re not out of pocket for that dispute.

Step 1: Customer starts the payment
The customer enters their card details and initiates a payment on your checkout page.

Step 2: Card issuer verifies the customer’s identity

The card issuer may prompt the customer to complete one or more authentication steps

Step 3: Payment is authorised

Once authentication is successful, the transaction proceeds to authorization. If a chargeback occurs, liability shifts to the card issuer.
