Use a built-in or custom standard

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.

2. 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.
