The Juniper Mist platform categorizes alerts into three main types to help administrators quickly identify the nature of a problem. These categories are Security, which covers threats like rogue APs; Infrastructure, which relates to the health and status of network devices like APs and switches; and Marvis, which includes alerts generated by the AI engine based on detected anomalies and service-level failures.

A. Users: While Mist monitors user experience, "Users" is not a top-level alert category. User-related issues are typically surfaced through Marvis Actions or Service Level Expectations (SLEs).

B. Site: Site is a scope or filter for viewing alerts and other data within the Mist portal, but it is not a fundamental category of alert type.
