What are the disadvantages with encrypting all files?

Iron Contributor

We are working with a client that has Office 365 E3 licenses. They want to protect their files from being accessed by external parties or ex-employees.

 

We are planning to implement Information Protection sensitivity labels. Since they only have E3, they won't be able to auto-apply sensitivity labels. Any label will need to be applied manually.

 

One approach we are considering is setting the default file label to encrypt the document and grant permissions to all staff. If a document is copied outside the network it will only be accessible to staff with an active account.

 

Is there any disadvantage with this approach?
