Deploy a managed ruleset in the dashboard for a zone
You can deploy and configure managed rulesets for a zone in Security > WAF > Managed rules.
To deploy a managed ruleset for several Enterprise domains in your account, refer to Deploy a managed ruleset in the dashboard for an account.

 Deploy a managed ruleset
To deploy a managed ruleset with the default configuration:
- Log in to the Cloudflare dashboard, and select your account and domain. 
- Go to Security > WAF > Managed rules. 
- Under Managed Rulesets, select Deploy next to a managed ruleset. 
This operation will deploy the managed ruleset for the current zone, creating a new rule with the Execute action.
 Enable or disable a managed ruleset
Select the Enabled toggle next to a managed ruleset to enable or disable it.
 Configure a managed ruleset
Configure a managed ruleset to:
- Define specific field values for one or more rules (for example, configure a rule with an action different from the action configured by Cloudflare).
- Disable one or more rules.
- Specify a custom filter expression to apply the rules in the ruleset to a subset of incoming requests.
To skip one or more rules, or entire WAF managed rulesets, add a WAF exception.
 Configure field values for all the rules
To configure rule field values for all the rules in a managed ruleset:
- Log in to the Cloudflare dashboard, and select your account and domain. 
- Go to Security > WAF > Managed rules. 
- Next to the Execute rule that deploys the managed ruleset you want to configure, select the managed ruleset name. 
- Under Ruleset configuration, set one or more rule fields from the available values in the drop-down lists. - For example, select the action to perform for all the rules in the ruleset from the Ruleset action drop-down list.  
- (Optional) To apply the rules in the ruleset to a subset of incoming requests instead of all requests, set the scope using a custom filter expression. 
- Select Save. 
 View the rules of a managed ruleset
You can browse the available rules in a managed ruleset and search for individual rules or tags.
Use the available filters in the Browse Managed Ruleset interface.
To view the rules of a managed ruleset:
- Log in to the Cloudflare dashboard, and select your account and domain.

- Select Browse rules.  
 Configure a single rule in a managed ruleset
To configure a rule in the Browse Managed Ruleset interface:
- Search for a rule using the available filters. You can search for tags. 
- Find the rule you want to configure in the results list. 
- In the result line for the rule you want to change, select the desired value for a field in the displayed drop-down lists. For example, select the rule action in the Action dropdown. - In some managed rulesets, you can also change the status of a rule using the toggle next to the rule.  
- Select Next, and then select Save. 
 Configure rules in bulk in a managed ruleset
To configure several rules at once in the Browse Managed Ruleset interface:
- Enter search terms in the available input to find the rules you want to configure. You can search for tags.  
- In the results list, select the checkboxes for all the rules you want to configure. - Alternatively, select a tag name under the search input to filter the rules with that tag, and then select the checkboxes for the rules you want to configure. 
- Update one or more fields for the selected rules using the drop-down lists displayed in the top right corner of the table.  
- Select Next. 
- If you selected a tag, a dialog appears asking you if any new rules with the selected tag should be configured with the field values you selected. - Select Do not apply to new rules to apply your configurations to the selected rules only.
- Select Apply to new rules if you want to apply your configurations to any new rules with the select tag.
 
- Select Save. 
 Specify a custom expression for the ruleset
To apply the rules in the ruleset to a subset of incoming requests, specify a custom filter expression for the rule that executes the managed ruleset.
- Log in to the Cloudflare dashboard, and select your account and domain. 
- Go to Security > WAF > Managed rules. 
- Next to the Execute rule that deploys the managed ruleset, select the managed ruleset name. 
- Select Edit scope. 
- Under Set Scope, select Custom filter expression. 
- Under When incoming requests match, define the scope for all the rules in the ruleset using a custom filter expression. Use the Expression Builder or the Expression Editor for defining the expression. For more information, refer to Edit expressions in the dashboard. 
- Select Next, and then select Save.
