Limiting sensitive data in notifications

AlphaSeb - The feature discussed in this article is only available via App Protection Policies (MAM) and as such is configurable (e.g., you could create an APP policy that only blocks org data for notifications on devices that are not enrolled and that are using an APP PIN).

The OS notification controls cannot be managed via App Protection Policies.

For enrolled devices, Apple does provide a number of notification controls per-app, however, the "Show Preview" setting is not one of the controllable settings - https://developer.apple.com/documentation/devicemanagement/notifications/notificationsettingsitem.
