<h2>Types of Rules Configurations</h2>
Fraud Shield for WooCommerce offers four main types of validation rules to protect your store from spam, fake accounts, and fraudulent orders:
<div class="twocol-one">
Registration Rules:
Safeguard your store from fake or spam user signups by validating critical fields during the registration process.
Available settings include username validation to block generic or numeric-only usernames, email username validation to block emails with suspicious local parts, and email domain validation to restrict sign-ups from known spam, disposable, or fake email domains.
</div>
<div class="twocol-one last"><img class="aligncenter size-full wp-image-18734005957183" src="https://woocommerce.com/wp-content/uploads/2025/10/registration_settings.png" alt="Registration settings" width="980" height="719" /></div>
<div class="twocol-one">Checkout Billing Address Rules:
Validate billing details during checkout to prevent fake orders and suspicious transactions. These rules identify incomplete, invalid, or mismatched billing data, stopping fraud before it reaches payment processing.
Available settings cover validation for billing details, including name, address, city, state, country, postal code, email, phone number, and company. This helps block fake, invalid, or disposable information to maintain data accuracy and prevent fraudulent or low-quality orders.
</div>
<div class="twocol-one last"><img class="aligncenter size-full wp-image-18734005957187" src="https://woocommerce.com/wp-content/uploads/2025/10/checkout-settings.png" alt="checkout settings" width="980" height="798" /></div>
Checkout Shipping Address Rules:
Ensure shipping details are accurate and legitimate. By blocking fake or bot-generated addresses, these rules reduce delivery issues, save fulfilment costs, and maintain a smooth order experience for genuine customers.
Available settings cover validation for shipping details, including first and last names, address, city, state, country, postal code, phone number, and company. This ensures the blocking of fake, invalid, or suspicious entries to maintain accurate and trustworthy order information.
<div class="twocol-one">
Technical Rules:
Go beyond basic form validation with system-level checks. Technical rules verify IP addresses, browsers, device types, and other metadata to detect patterns linked to fraudulent behavior. This adds a powerful, invisible layer of protection that works in real time.
Available settings include validation for IP address, device, browser, operating system, email domain, user role, and user ID, allowing you to block traffic from suspicious sources, outdated systems, disposable email domains, restricted user roles, or known spam accounts.
</div>
<div class="twocol-one last"><img class="aligncenter size-full wp-image-18734005957189" src="https://woocommerce.com/wp-content/uploads/2025/10/technical-settings.png" alt="Technical Settings" width="980" height="894" /></div>
With these four layers of configurable rules, Fraud Shield provides precise, proactive control over fraud prevention, helping you block bad actors without disrupting genuine customers.

<h2>Global Settings</h2>
The General Settings section allows store owners to manage the core functionality of the Fraud Shield for WooCommerce extension.
It provides global controls to enable or disable the extension, configure how fraud detection rules behave, and manage logging for security insights and debugging. These settings help ensure that validation rules are applied efficiently while offering visibility into all blocked attempts. <img class="aligncenter size-full wp-image-18734005957198" src="https://woocommerce.com/wp-content/uploads/2025/10/global-settings.png" alt="Global Settings" width="980" height="654" /> 
<hr class="wccom-product-heading__hr" />
<h2>Blocked User Section</h2>
The “Blocked User” section of this extension offers a comprehensive dashboard that lists all users who were blocked due to failing fraud detection rules during registration or checkout.
<img class="aligncenter size-full wp-image-18734005957209" src="https://woocommerce.com/wp-content/uploads/2025/10/blocked-users.png" alt="blocked users" width="980" height="560" />
<hr class="wccom-product-heading__hr" />
<h2>Prevent fraudulent registrations from specific email domains</h2>
Scenario: You want to prevent fake account creation using disposable emails and suspicious addresses, commonly used for testing or fraudulent purposes.


Steps to create the validation rule:

<ol class="wp-block-list">
<li>In your store’s WP Admin dashboard, go to WooCommerce > Settings > Fraud Shield.</li>


<li>Add a Registration Rule:
<ul class="wp-block-list">
<li style="list-style-type: none">
<ul class="wp-block-list">
<li>Enable fraud shield for registration</li>

</ul>
</li>
</ul>
<ul class="wp-block-list"></ul>
</li>


<li>Now, if a customer adds an email with a domain name that is blocked with error message. <img src="https://woocommerce.com/wp-content/uploads/2025/10/user-registration-validation.png" alt="" /></li>
</ol>

<h2>How to Block Fraud Orders</h2>
Configure to protect your WooCommerce store by blocking fraudulent orders automatically. Use smart filters like user email, name, and other identifiers to stop scammers before checkout.

<ul class="wccom-tick-list-primary">
<li>Block by Email Address – Add suspicious or blacklisted email IDs to automatically prevent new orders.</li>
<li>Block by Customer Name – Stop repeat offenders or fake name patterns (e.g., “Test User,” “Demo Buyer”).</li>
<li>Block by Domain – Restrict orders from disposable or spammy email domains like @tempmail.com.</li>
