# Create a content security rule in the dashboard

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/client-side-security/rules/create-dashboard/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Note

Only available to customers with Client-Side Security Advanced.

1. In the Cloudflare dashboard, go to the **Security rules** page.  
[Go to **Security rules** ↗](https://dash.cloudflare.com/?to=/:account/:zone/security/security-rules)
2. Select **Create** \> **Content security rules**.
3. Enter a descriptive name for the rule in **Description**.
4. Under **If incoming requests match**, define the scope of the content security rule (or policy). You can use the Expression Builder (specifying one or more values for **Field**, **Operator**, and **Value**) or manually enter an expression using the Expression Editor. For more information, refer to [Edit expressions in the dashboard](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ruleset-engine/rules-language/expressions/edit-expressions/).
5. Under **Allow these directives**, select the desired [CSP directives](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/client-side-security/rules/csp-directives/) for the content security rule by enabling one or more checkboxes.

  * To manually enter an allowed source, select **Add source**.
  * To refresh the displayed sources based on detected resources, select **Refresh suggestions**.  
  Note  
  Cloudflare provides suggestions for **Default**, **Scripts**, and **Connections** directives. For the **Default** directive, suggestions are based on monitored scripts and connections resources.
6. Under **Then take action**, select the desired action:
  * _Allow_: Enforces the CSP directives configured in the rule, blocking any other resources from being loaded on your website, and logging any [rule violations](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/client-side-security/rules/violations/).
  * _Log_: Logs any content security rule violations without blocking any resources not covered by the rule.
7. To save and deploy your rule, select **Deploy**. If you are not ready to deploy your rule, select **Save as Draft**.
