Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Adding a managed rule group to a web ACL through the console

This guidance applies to all Amazon Managed Rules rule groups and to the Amazon Web Services Marketplace rule groups that you're subscribed to.

Production traffic risk

Before you deploy changes in your web ACL for production traffic, test and tune them in a staging or testing environment until you are comfortable with the potential impact to your traffic. Then test and tune your updated rules in count mode with your production traffic before enabling them. For guidance, see Testing and tuning your Amazon WAF protections.


Using more than 1,500 WCUs in a web ACL incurs costs beyond the basic web ACL price. For more information, see Amazon WAF web ACL capacity units (WCUs) and Amazon WAF Pricing.

To add a managed rule group to a web ACL through the console
  1. Sign in to the Amazon Web Services Management Console and open the Amazon WAF console at

  2. Choose Web ACLs in the navigation pane.

Test and tune any changes to your Amazon WAF protections before you use them for production traffic. For information, see Testing and tuning your Amazon WAF protections.

Temporary inconsistencies during updates

When you create or change a web ACL or other Amazon WAF resources, the changes take a small amount of time to propagate to all areas where the resources are stored. The propagation time can be from a few seconds to a number of minutes.

The following are examples of the temporary inconsistencies that you might notice during change propagation:

  • After you create a web ACL, if you try to associate it with a resource, you might get an exception indicating that the web ACL is unavailable.

  • After you add a rule group to a web ACL, the new rule group rules might be in effect in one area where the web ACL is used and not in another.

  • After you change a rule action setting, you might see the old action in some places and the new action in others.

  • After you add an IP address to an IP set that is in use in a blocking rule, the new address might be blocked in one area while still allowed in another.
