How Microsoft Purview DLP currently can help you protect confidential data in Copilot.

on
Organizations today face a difficult balancing act. Business leaders are eager to adopt tools like Microsoft Copilot to unlock productivity and innovation. Meanwhile, IT and security teams are concerned about safeguarding sensitive information, especially as AI-driven features process vast amounts of organizational data. This tension is real: enabling advanced capabilities without compromising compliance or data protection is a challenge every modern enterprise must solve. Microsoft Purview Data Loss Prevention (DLP) is a key solution to this problem. It provides mechanisms to prevent confidential data from being exposed or misused, even in scenarios involving AI. I want to highlight two features designed to help organizations in controlling what is being processed by Copilot. Blocking Documents Based on Sensitivity Labels One of the foundational features of Purview DLP is its ability to enforce policies based on Microsoft Information Protection sensitivity labels.

Microsoft Teams Guest Access for all (Not just MSA)

on

A truly collaborative platform

For a collaboration tool to be truly collaborative, it needs to support not only most kind of devices but it should also be able to include users from across the globe. For some time now, Slack and Google hangout have kind of ruled this space, by being able to bring people together based on a simple e-mail address, and not making it a prerequisite to be a subscriber of their services.

Microsoft Teams first version of Guest Access had the limitation of only being able to invite other users from companies who also were users of Office 365.

Their second version expanded this functionality to users with a so called MFA (much like Skype Consumer federation was limited to users with a "Microsoft" account).

But all that is gone now. It was just announced that the support for all kinds of guest access into Teams will be supported, and here is quick glance at how it looks.

Prepare the tenant

Guest access is controlled by the Admin of the tenant, and in order for it to work, the administrator needs to set the propper rights and licencing in the portal. This is quite easy done like this:
  • Click Settings
  • Click Services & Add-ins
  • Select "Microsoft Teams"
  • Select "Settings by user/license type"
  • Select "Guest" in the drop down list
  • Verify the option is set to "On"


Invite the user

Once the settings are implemented (Note: the setting is global), users may invite guest by entering an email address in the "add member" dialog:


This will send an email to your contact, which will contain a link to initiate the participation.




After the initial sign in, the user may choose download the client or participate in the web browser of his or her choice, and participate fully with everyone in the team.

I have been playing around with this for a while, and I see this as a great development of Teams, strengthening it's position in the market.
