Without a doubt, Microsoft Teams is a key asset in corporate communications today. To improve collaboration, Microsoft provides the ability to add external users as guests in
external tenants.
This increases productivity, but on the other hand can introduce new risks, especially if your users are guests of other tenants and are not bound by your company policy at this
time.
The guest option is actually a corporate compliance and governance loophole that must be addressed.
The Problem
Scenario
An internal user (let's call him "employee") joins an external tenant (another company) as a guest.
The risks associated with this situation are enormous. For example, as described in this article, Microsoft DLP policies will not apply, which could mean data leakage without any
precautions.
Another example is that a company might disable certain features in Teams for compliance reasons, such as file sharing. These policies will not apply when your users are guests of other tenants.
How to solve
SphereShield Ethical Wall for Microsoft Teams provides functionality as part of the Teams Governance/Ethical Wall feature. By setting up rules, administrators can block all or specific groups of
employees from communicating with external tenants in any form.
Furthermore, it is possible to set unlimited rules to control the communication between users (or groups) and internal users, groups or external users (or domains).
SphereShield also provides the ability to prevent users from joining meetings anonymously
