Protecting against Data Loss in Microsoft Teams Meeting Chats

In my recent blog called My Teams Security Slide I called out support for Data Loss Prevention (DLP) Policies for Microsoft Teams. I think most IT Pros are very familiar with these native platform controls built into Microsoft 365 and may have already applied them to Microsoft Teams Chats and Channels.

One thing I always point out is these same polices will be applied during a Microsoft Teams Meeting to protect against accidental data loss from within the Meeting Chat. This short video demo provides an example use case:

So in the video above Joni invites Adele to a meeting in her Microsoft 365 tenant and is protected from erroneously sharing credit card information. But what happens when Joni is in a meeting that’s hosted in an external tenant?

She is still protected! Check this video out:

Securing Teams Meetings Content Sharing

I recently posted a short blog called My Teams Security Slide, which contained an overview of the security controls I associate with Microsoft Teams. One of the features I listed was “Sensitivity Labels for Content”, which for organisations concerned about data loss prevention is a way of classifying content and applying security policies.

So what does this has to do with a Teams Meeting?

Microsoft 365 Sensitivity Labels actually allow administrators to managed document permissions and Microsoft Teams will honour these. One of the net effects is that is that you can restrict the ability to share confidential documents during a Teams Meeting.

I created this video to demonstrate the resulting end user experience.

This is a great way to protect against accidental data loss during a Microsoft Teams share. But what about policing a Teams Meeting chat? I’ll talk about this in a future post.
