Microsoft will soon introduce support for third-party deepfake detection solutions and impersonation protection in Teams meetings.
According to new entries on the Microsoft 365 Roadmap, both changes are now in development and will reach general availability in November after a worldwide rollout.
Once available, Microsoft says it will provide Teams integration and experiences to surface and act on deepfake detection signals triggered by supported providers.
"Organizations can enhance meeting security with synthetic audio and video detection solutions provided by certified third-party providers," Microsoft said.
"Third-party detection solutions analyze meeting media for signs of synthetic or manipulated audio and video and send detection signals to Teams, enabling integrated in-meeting experiences and controls."
Teams will also let users detect deceptive meeting organizers and participants through a new impersonation protection security feature.
"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," the company added.
These changes are part of a broader move to boost security for Teams users, with Microsoft also announcing in December that admins would be able to lock external users via the Defender portal starting in January to thwart cybercrime groups (including ransomware gangs) abusing Teams in social engineering attacks targeting their victims' employees.
Last month, it added that Teams will blur QR codes sent by external senders to provide additional protection against phishing and fraud attempts.
Microsoft also began rolling out a new Teams meeting protection policy in August that lets admins block all identified external bots automatically from joining meetings.
More recently, in September, it also announced that it will let users report suspicious guest invitations directly from Teams starting in November to help security teams identify and block phishing attempts and other attacks abusing guest invitations.
