# Users, roles, and domains

In SitecoreAI, access security is controlled on three levels:

- [user](https://doc.sitecore.com/sai/en/developers/sitecoreai/user-security/users-roles-and-domains/creating-users-in-sitecoreai.html "Creating users in SitecoreAI") - an individual user
- [role](https://doc.sitecore.com/sai/en/developers/sitecoreai/user-security/users-roles-and-domains/create-and-set-up-a-role.html "Create and set up a role") - a collection of users. Roles enable you to assign access rights to a group of users instead of to an individual user
- [domain](https://doc.sitecore.com/sai/en/developers/sitecoreai/user-security/users-roles-and-domains/security-domains.html "Security domains") - a collection of security accounts

With these three levels of security, you can control all user access to SitecoreAI functionality and website content.
