Block upload of documents to other office 365 tenant
Do you mean sharing documents with other tenants? because upload means they already have access to those tenants as guests maybe and the other tenants should take the action from their sides not yours.
If you're talking about sharing files with another domains/tenant, as i know you can get prevent that using a File Policy in MCAS
Also you can use entire organization instead of Any Any from domain.
Cheers,
I am not talking about sharing or collaborating here, I am talking about upload.
on my corporate device, i can log in to any office 365 tenant and upload documents of my tenant, i want to restrict to only single tenant
This is not even related to uploading or sharing files, if you don't want your corporate devices access to other tenants you need to use Azure AD tenant restrictions, take a look https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/tenant-restrictions
I hope this will be helpful.
- What about non-cooperate devices?
What if all data is encrypted? What happens to sharing or uploading or any other means of exfiltration?
Sharing, uploading, it doesn't matter if the data is encrypted and only corporate devices can be used to authenticate so they can access the data.
