# Use a built-in or custom standard
Use built-in standards or create and edit custom standards for your organization.
You can use a built-in industry standard or create a custom standard. A custom standard can be either a copy of a built-in standard or a custom standard created from scratch.
## Use a built-in standard
Cortex provides built-in industry approved regulatory compliance standards, for example **GDPR**. These standards cannot be edited or deleted, you can duplicate them to create a custom standard.
## Clone a built-in standard
To reuse and modify a built-in standard, clone the built-in industry standard:
1. In the **Standards** catalog, right-click on the built-in standard you want to edit or select 
from the standard's side pane.
2. Select **Save as new**.
3. Define compliance standard metadata, including:
1. **Name**: By default, the original built-in standard name is used with “\_copy“ is appended. You can update it if needed.
2. **Description**: You can update the description if needed.
3. **Select Controls**: You can select or deselect controls as needed.
4. Click **Create**.
## Create a custom standard
You can create a custom compliance standard that is tailored to your own business needs and organizational policies.
To organize controls within a custom compliance standard, you establish categories and optional sub-categories. Every control is defined as part of a specific standard and assigned to a single category within it. Sub-categories offer an additional layer of organizational structure.
1. In the **Standards** catalog, click **Create Standard**.
2. Define compliance standard metadata, including:
1. **Name**
2. **Description** (optional)
3. **Labels** (optional)
3. Click **Next.**
4. Under **Select Controls**, you select the controls that you would like to add to the standard.
5. Click **Create**.
## Manage existing custom standards
Custom compliance standards can be managed from **Posture Management → Compliance → Standards Catalog.** Right click on a standard or select from the standard's side pane to edit or delete it. You can edit all parameters of the standard and update the list of controls assigned to it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://cortex-docs.paloaltonetworks.com/cortex-cloud-runtime-security/compliance/monitor-and-track-compliance-adherence/choose-compliance-standards-from-the-compliance-catalog/use-a-built-in-or-custom-standard.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
