# Radar Rules

Radar Rules are a feature of Radar Plus and Radar Pro that help you fine-tune how Radar can work for you to prevent fraud. Rules allow you to block, review and allow payments based on criteria that you choose, according to your business needs.
Rules are available to Stripe accounts that have upgraded to Radar Plus or Radar Pro. See [our pricing page](https://stripe.com/radar/pricing) for more information.
