Handling Fraud Effectively: Automatically cancel or pause suspicious orders

Setting to hold or cancel orders with high risk factor.

If a potentially fraudulent transaction is detected, the WooCommerce Anti-Fraud will automatically block or prevent these orders based on your specific configuration. The plugin can easily be configured to perform one or more of the following automated actions:

  • Automatically Cancel the order.
  • Automatically place the order On-Hold.
  • Email Admin + Notify store of Suspect Order without changing the order status.
  • Auto Blacklist email and other Order Details.
  • Prevent Bank/Payment Gateway access (Pre-payment verification)

Pre-Configured Rules

WooCommerce Anti-Fraud works out of the box – no need for additional rule configuration. We have defined a collection of default rules that automatically assess and scores each transaction. These pre-configured rules are suitable for most online stores. Moreover, you can easily customize the rules to suit your preferences with just a few clicks and to place higher or lower importance on specific factors/rules.

Customize the importance of each risk factor

The WooCommerce Anti-Fraud plugin lets you assign a ‘risk weight’ to each risk factor. This means that you can decide how important each risk is and configure this to your specific sotore. The higher the risk weight for each category, the higher the consideration will be given to the rule in calculating the overall risk score when the risk is detected.

First-time Purchase Rules

First time purchase rule

Identify first-time customers or their initial order in a processing state. This rule also allows you to
recognize new customers. Allow Antifraud to understand and make it easier for your existing clients to shop and repurchase.

Harness the Power of Machine Learning with Maxmind minFraud® integration

minfraud

WooCommerce Anti-fraud now includes integration with the Maxmind minFraud Score tools. Now, combine existing rules with a smart real-time risk score for each order. This feature gives you an extra layer of security by assessing orders for fraudulent activities using a smart machine learning algorithm by MaxMind. Enabling this feature, you will be notified about the status of the order when the risk score exceeds the threshold set in the minFraud Settings.

Ordered Quantity and Amount Check

order amounts

These two features can help you reduce chargebacks effectively. You can set the maximum buying amount, number of products and even weighting based on the type of products you are selling to counter fraudulent activities.

Access Ecommerce Fraud Prevention Experts

Check the ‘risk’ of each order

antifraud

WooCommerce Anti-Fraud plugin automatically assigns a risk score to each order on a scale of 1 to 100. The higher the score, the greater the likelihood of the order being fraudulent. This is called the risk score. Examining the risk score enables you to quickly evaluate the potential risk associated with the transaction and take the appropriate defensive actions. You can find the risk score and receive advice for each order directly within the WooCommerce admin panel.

Beneath the risk score, users can see any warnings linked to the order. The advice provided is related to the rules in place (for example, if a customer’s IP address doesn’t match the billing country). The higher this number is, the more likely it is that the order is potentially fraudulent.

Whitelisting of User Roles, Payment Methods and Emails

Settings to whitelist user roles, payment methods and emails

Pre-Purchase Assessment of Risk

Pre purchase assessment of orders

Evaluate customers before they make actual purchases through your Payment Gateway.

If the risk score reaches a high-risk order range, the customer order will be denied in advance, a custom message will appear on the checkout explaining the reason for denial. Add a custom message by typing in the text area in the pre-purchase setting.
