# Review policy

Before you implement a policy on an NGINX instance or Config Sync Group, you may want to review it. F5 NGINX One Console creates a policy for your F5 WAF for NGINX system.

## Review F5 WAF for NGINX policies

From NGINX One Console, select **WAF** > **Policies**. Select the name of the policy that you want to review. You'll see the following tabs:

- Details, which includes:
  - Policy Details: Descriptions, status, enforcement type, latest version, and last deployed time.
  - Deployments: List of instances and Config Sync Groups where the F5 WAF for NGINX policy is deployed.
- Policy JSON: The policy, in JSON format. With the **Edit** button, you can modify this policy.
- Versions: Policy versions that you've written, labeled sequentially (`v1`, `v2`, `v3`, and so on). Each version shows its name, creation date, enforcement mode, and optional version comment. Select a version to view its details or update its comment. You can also apply an older policy version to your deployments.

## Modify existing policies

From the NGINX One Console, you can also manage existing policies. In the Policies screen, identify a policy, and select **Actions**. From the menu that appears, you can:

- **Edit** an existing policy.
- **Save As** to save an existing policy with a new name. You can use an existing policy as a baseline for further customization.
- **Deploy Latest Version** to apply the latest revision of an existing policy to the configured instances and Config Sync Groups.
- **Export** the policy in JSON format.
- **Delete** the policy. Once confirmed, you'll lose all work you've done on that policy.

**Note:** 
If you use **Save As** to create a new policy, include the `app_protect_cookie_seed` [directive](/waf/policies/directives.md).
