There are five types of users:

Standard Users 
Regular users who can be given various Permissions and have Edit rights to as much or as little of the platform as you decide.
View-Only Users
Users who can only view certain parts of the platform depending on the Permissions you assign them. They require a special license.
Collaborator Users
Users who can be assigned to edit/view various Platform modules, depending on the Permissions you give them.  For more information on collaborator users, click here.
Managed Users
Users who are similar to collaborator users. They have full case management permissions and therefore are capable of running Hybrid SOC model together with the MSSP.  Note that Managed users have no access to edit playbooks.  For more information on Managed Users, click here.
Managed-Plus Users
Users who have the same full case management permissions as the managed user plus the ability to build and edit playbooks on their own environment. For more information on Managed-Plus Users, click here.
