Microsoft Teams Will Add Third-Party Deepfake Detection and Impersonation Warnings to Meetings in November

Microsoft is preparing to add support for third-party deepfake detection tools and a new impersonation protection feature to Microsoft Teams meetings, according to two new entries on the Microsoft 365 Roadmap. Both features are listed as in development, and Microsoft plans to reach general availability in November after a worldwide rollout.

The deepfake detection itself will not come from Microsoft. Teams acts as the surface for detection signals sent by certified third-party providers, while the separate impersonation protection feature is built into Teams and flags suspicious meeting organizers and participants.

How Deepfake Detection Signals Work in Teams Meetings

According to the roadmap entry, organizations will be able to "enhance meeting security with synthetic audio and video detection solutions provided by certified third-party providers."

Those providers analyze the audio and video of a meeting for signs of synthetic or manipulated media. When a solution finds something, it sends a detection signal to Teams.

Microsoft says it will provide the Teams integration and the in-meeting experiences and controls that surface those signals and let organizations act on them. The roadmap entries do not name the certified providers, and Microsoft has not said whether the integration requires an additional license.

Impersonation protection targets identity rather than media. "When Teams detects a potential impersonation attempt, it surfaces warnings and risk indicators to help users recognize suspicious identities and make more informed decisions when joining or participating in a meeting," Microsoft states in the second roadmap entry.

Why Microsoft Keeps Adding Protection to Teams

The two features continue a series of Teams security changes. Cybercrime groups, ransomware gangs among them, have abused Teams for social engineering attacks aimed at the employees of victim organizations, in some cases by posing as IT support.

Microsoft has answered with a run of smaller controls:

• admins can lock out external users through the Defender portal, a change Microsoft announced in December with availability from January
• a meeting protection policy, rolling out since August, automatically blocks identified external bots from joining meetings
• Teams blurs QR codes sent by external senders to cut down on phishing and fraud attempts
• Users will be able to report suspicious guest invitations directly from Teams starting in November

The changes fit a wider tightening across Microsoft 365, which also includes blocking .msix attachments in new Outlook from November.

Teams administrators who plan to use deepfake detection should track the two roadmap entries and check which certified providers become available once the rollout starts. Organizations that already work with a synthetic media detection vendor can ask whether that vendor is pursuing certification for Teams.

Microsoft has not published a specific November date for either feature, and the roadmap entries do not explain how admins will turn them on.
