Deepfake detection is coming to Teams meetings
Microsoft is preparing to add support for third-party deepfake detection solutions in Teams meetings, giving organizations a way to surface signals about potentially synthetic or manipulated audio and video during calls. The feature is listed among new Microsoft 365 Roadmap entries and is currently in development.
Microsoft said the deepfake detection capability is expected to reach general availability in November following a worldwide rollout. The company has not identified the third-party providers that will be supported, but its roadmap description refers to certified providers whose solutions can analyze meeting media and send detection signals to Teams.
How third-party signals will work
According to Microsoft, supported detection services will examine audio and video from a meeting for indications that the content has been synthetically generated or manipulated. Those services will then send their findings to Teams, where Microsoft plans to provide integrated in-meeting experiences and controls.
The planned integration is designed to let organizations use external detection technology without separating the analysis from the Teams meeting experience. Microsoft’s description focuses on surfacing and acting on signals from providers rather than replacing those providers’ detection systems with a native Teams model.
Warnings for possible impersonation attempts
Teams is also set to receive a separate impersonation protection feature aimed at deceptive meeting organizers and participants. When the service detects what may be an impersonation attempt, it will show warnings and risk indicators to help users assess whether a meeting identity appears suspicious.
The company added that these indicators are intended to help users make more informed decisions when joining or participating in a meeting. The source material does not specify which signals Teams will use to identify a possible impersonation attempt or how administrators will configure the feature.
Part of a broader Teams security effort
The two planned capabilities are part of a broader series of security changes for Teams. Microsoft previously announced that admins would be able to lock external users through the Defender portal starting in January, a measure intended to counter cybercrime groups and ransomware gangs that abuse Teams in social engineering attacks against employees.
Microsoft also said Teams would blur QR codes sent by external senders to provide additional protection against phishing and fraud attempts. The company began rolling out a meeting protection policy in August that allows administrators to automatically block all identified external bots from joining meetings.
More protections planned for guest invitations
In September, Microsoft announced another Teams security measure that will let users report suspicious guest invitations directly from the application starting in November. The reports are intended to help security teams identify and block phishing attempts and other attacks that misuse guest invitations.
Microsoft has not provided further implementation details for the deepfake detection integration or impersonation protection in the material announcing the features. For now, the company’s roadmap indicates that both are in development and are scheduled for general availability in November, with availability following a worldwide rollout.
