What are the three types of Zendesk Instances regarding End-User access?

The correct classification of Zendesk instances concerning end-user access consists of three types: Open, Restricted, and Closed.

An Open instance allows any user to create a ticket or access content without any specific verification or validation. This is ideal for organizations that want to provide broad access and ease of use.

A Restricted instance limits user access based on certain criteria or roles. In this setup, only authenticated users or those with specific permissions can access certain features or content, balancing user accessibility with security concerns.

Closed instances are the most restrictive. Access is granted only to users or groups that have been explicitly invited or given permissions by the organization. This would be suitable for confidential information or when privacy is a premium.

These distinctions play a critical role in how businesses manage their customer interactions, define user roles, and secure sensitive data, ensuring that end-users have appropriate access consistent with organizational policies.
