# AWS Control Tower proactive controls as Hooks
<a name="proactive-controls-hooks"></a>

The AWS Control Tower Control Catalog provides pre-built compliance rules (proactive controls) that you can implement as Hooks. This approach saves setup time and helps you validate resource configurations against AWS best practices across your organization without writing code. 

Proactive controls evaluate AWS resources before deployment, preventing non-compliant resources from being created rather than detecting issues later. They check configurations against established security, operational, and governance standards. 

To get started, simply activate proactive control-based Hooks in your desired account and Region. These Hooks will then evaluate specific target types to ensure compliance with your selected controls. 

For more information about available proactive controls, see the [AWS Control Tower Control Catalog](https://docs.aws.amazon.com/controltower/latest/controlreference/controls-reference.html).
