# Create and set up filters (/platforms/checkout/advanced/customize/fraud-protection/fraud-protection-advanced/filters)



Filters are the rules that decide whether Fraud Protection Advanced (FPA) approves, rejects, or puts a transaction into a review queue.

The **Filters** tab shows customized filters that merchants can enable, adjust, or create as needed. Your merchants can also see simulations based on the current filter settings applied to their historical data for a selected time period.

> **Info:** All customized filter recommendations are disabled by default. To activate them for fraud detection, your merchants must manually enable relevant filter suggestions.
