Microsoft will add support for third-party deepfake detection and impersonation protection to Teams meetings, according to new entries on the Microsoft 365 Roadmap. Both capabilities are listed as in development and are set to reach general availability in November following a worldwide rollout. The changes are aimed at organizations that rely on Teams for meetings and want additional safeguards against manipulated media and deceptive participants.
Microsoft said the deepfake detection feature will provide Teams integration and experiences that surface and act on detection signals triggered by supported providers. Organizations will be able to enhance meeting security using synthetic audio and video detection solutions supplied by certified third-party providers, according to the company. Those providers analyze meeting media for signs of synthetic or manipulated audio and video and send detection signals to Teams, which enables integrated in-meeting experiences and controls.
The second addition, impersonation protection, is designed to help users identify deceptive meeting organizers and participants. Microsoft said that when Teams detects a potential impersonation attempt, it surfaces warnings and risk indicators so users can recognize suspicious identities and make more informed decisions when joining or participating in a meeting. The feature is part of the same roadmap update as the deepfake detection integration.
The new capabilities fit into a broader effort by Microsoft to strengthen security for Teams users. In December, the company announced that admins would be able to lock external users through the Defender portal starting in January, a move intended to counter cybercrime groups, including ransomware gangs, that abuse Teams in social engineering attacks targeting victims' employees. In August, Microsoft began rolling out a Teams meeting protection policy that lets admins automatically block all identified external bots from joining meetings.
Microsoft has also taken steps against phishing and fraud in recent months. Last month, it said Teams will blur QR codes sent by external senders to provide additional protection against phishing and fraud attempts. In September, it announced that users will be able to report suspicious guest invitations directly from Teams starting in November, helping security teams identify and block phishing attempts and other attacks that abuse guest invitations.
For US organizations, the November availability means Teams administrators and security teams will soon have third-party deepfake detection signals and impersonation warnings available inside meetings, alongside the earlier external user, bot, QR code and guest invitation controls. The roadmap entries describe the features as in development, with general availability planned after a worldwide rollout.
