In order to limit admin access in Sphereshield portal, please follow these steps:
Under settings go to “Site Security”
Change the setting "Users can only see Teams they have permissions on" to yes.
3. Click the “Add” button to add users as Admins. Please be sure to also add the compliance administrator you configured in the initial configuration of the portal as an “Admin with settings access”
4. Start typing the names of the users you wish to configure and pick them from the drop down menu. You’ll need to configure at least one admin with settings access and one without. This will lock out other users from accessing the portal
After the configuration is complete, only the compliance admin will have access to all the teams on the tenant.
As long as you perform actions with the other users configured as admins, they will only have access to their own teams.
