# Fraud prevention

Digital River’s in-house fraud engine is Transaction Defender. Based on its evaluation, Digital River accepts or declines a transaction. No manual setup is required. See [Ecommerce Fraud Protection](https://www.digitalriver.com/global-seller-services/fraud/) for details.

{% hint style="info" %}
 If the **Order Status** in BigCommerce is set to **Manual Verification Required**, the merchant does not need to take action; Digital River manually reviews the transaction.
