Abstract: According to examples, an apparatus for managing alerts pertaining to additions of users to a user group in a computer network may include a processor and a memory, which may have stored thereon machine readable instructions that are to cause the processor to, during a learning period, identify an entity that added a user to the user group during the learning period and enter an identification of the identified entity into an allowed entity list for the user group. Following the learning period, the instructions are to cause the processor to identify a user addition event that indicates that an adding entity added another user to the user group, determine whether the adding entity is in the allowed entity list, and manage issuance of an alert regarding the user addition event based upon whether the adding entity is in the allowed entity list to reduce a number of issued alerts.
