+## Persona's
+
+#### Global
+Global is a persona/placeholder for policies that are general 
+in nature or do not only apply to one persona. So it is used 
+to define policies that apply to all personas or don't apply to 
+one specific persona. The reason for having this persona is to 
+be able to have a model where we can protect all relevant 
+scenarios. It should be used to hold policies that apply to all 
+users or policies that enforce protection on scenarios not 
+covered by policies for other personas
+
+#### Admins
+We define admins in this context as any non-guest identity 
+(cloud or synced) that have any Azure AD or other Microsoft 
+365 admin Role (like in MDCA, Exchange, Defender for 
+Endpoints or Compliance). As guests who have such roles are 
+covered in a separate persona, guests are excluded from this 
+persona.
+
+#### Internals
+Internals cover all users who have an AD account synced to 
+Azure AD who are employees of the company and work in a 
+standard end-user role.
+
+#### Guests
+Guests holds all users who have an Azure AD guest account 
+that has been invited into the customer tenant
