Deploy a WAF managed ruleset in the dashboard

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.

Example WAF Managed Rules configuration in the Managed rules tab under Security > WAF. There are two managed rulesets already deployed, and one managed ruleset available for deployment.

Deploy a managed ruleset

To deploy a managed ruleset with the default configuration:

  1. Log in to the Cloudflare dashboard, and select your account and domain.

  2. Go to Security > WAF > Managed rules.

  3. 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.

Turn on or off a managed ruleset

Select the Enabled toggle next to a managed ruleset to turn it on or off.

Configure a managed ruleset

Configure a managed ruleset to:

  • Specify a custom filter expression to apply the rules in the ruleset to a subset of incoming requests.
  • Define specific field values for one or more rules (for example, configure a rule with an action different from the action configured by Cloudflare), or turn off those rules.

To skip one or more rules — or even entire WAF managed rulesets — for specific incoming requests, add an exception.

Configure field values for all the rules

To configure rule field values for all the rules in a managed ruleset:

  1. Log in to the Cloudflare dashboard, and select your account and domain.

  2. Go to Security > WAF > Managed rules.

  3. Next to the Execute rule deploying the managed ruleset you want to configure, select the managed ruleset name.
    If you have not deployed the managed ruleset yet, select the managed ruleset name under Managed Rulesets.

  4. (Optional) To execute the managed ruleset for a subset of incoming requests, select Edit scope and configure the expression that will determine the scope of the current rule deploying the managed ruleset.

  5. In the ruleset configuration section, define settings for all the rules in the ruleset by setting one or more fields using 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.

    The Configure Managed Ruleset page displaying the available options to override all the rules in the ruleset. In the displayed managed ruleset you can override the ruleset action.

  6. If you are editing a deployed managed ruleset, select Save. If you have not deployed the managed ruleset yet, select Deploy to deploy the ruleset immediately, or Save as Draft to save your deployment settings for later.

Configure rules in bulk in a managed ruleset

  1. Log in to the Cloudflare dashboard, and select your account and domain.

  2. Go to Security > WAF > Managed rules.

    Selecting all rules in a page displays additional drop-down lists above the table to override the behavior of several rules at once.

  3. Update one or more fields for the selected rules using the buttons displayed in the top right corner of the table.

  4. Select Next.

  5. 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.
