# Cloud Cleaning

Cloud cleaning ensures the availability of the entire network by connecting to the cloud cleaning service provider for upstream traffic cleaning based on alarm policy settings in case of network faults caused by massive volumes of attack traffic.

Before you configure cloud cleaning, ensure that you have contracted the service from the cloud cleaning service provider.
