About
Customers with Virtru for Drive subscriptions have various options on how to protect their Drive content. This includes the ability to configure a Google service account for Shared Drive compatibility. This allows users to access encrypted content in any Shared Drive they are a member of.

Service account setup
Background
Virtru needs to make real-time access-based decisions around whether a user is allowed to access content within a particular Shared Drive. To do so, Virtru must utilize a “service account” from Google to make calls to the Shared Drive API. This service account needs the drive.metadata.readonly scope.
The specific calls we will be making are outlined here: Drives: list
A service account is needed because Shared Drive functions differently than My Drive with respect to how files are owned and shared. Shared Drive limits files moving into and out of the Shared Drive and is intended to support established teams with expected membership changes and user turnover. In order to support this complex flow, Virtru must determine access permissions based on Shared Drive membership at the time of each access attempt.
Will a service account always be needed?
Virtru has investigated the available options from Google to ensure that proper file access is maintained for Shared Drive files. With the available APIs, the service account approach outlined in this document is the best path forward.
We are working in partnership with Google to ensure that Shared Drive APIs are evolving and maturing to accommodate more granular permissions.
