"Organizations can enhance meeting security with synthetic audio and video detection solutions provided by certified third-party providers," Microsoft said.
Microsoft Teams integration with third‑party deepfake detection providers
Microsoft will add support for third‑party deepfake detection solutions in Teams meetings, according to new entries on the Microsoft 365 Roadmap. The company says the capability is in development and will reach general availability in November after a worldwide rollout.
Microsoft described how the feature will work: third‑party detection solutions will analyze meeting media for signs of synthetic or manipulated audio and video and then send detection signals to Teams. Those signals will be surfaced inside Teams to enable what Microsoft calls "integrated in‑meeting experiences and controls."
Impersonation protection: warnings and risk indicators
Alongside deepfake detection, Teams will introduce an impersonation protection security feature aimed at deceptive meeting organizers and participants. "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 said.
The two additions — synthetic audio/video detection and impersonation protection — are presented as complementary: detection solutions flag manipulated media while the impersonation feature highlights suspicious identities and seeks to influence user behavior during meetings.

End the scrambleRollout timing and related admin controls
Microsoft lists both features as entering development on the Microsoft 365 Roadmap and specifies a November general availability after a worldwide rollout. The company has previously signaled related administrative controls: in December Microsoft announced that admins would be able to lock external users via the Defender portal starting in January to hinder "cybercrime groups (including ransomware gangs) abusing Teams in social engineering attacks targeting their victims' employees."
Those administrative controls sit alongside the in‑meeting signals from certified third‑party providers — a combination of prevention, detection and response designed to let organizations both limit access and act when suspicious media or identities are detected.
Recent Teams anti‑abuse features: QR code blurring, bot blocking, guest‑invite reporting
- QR code blurring: Microsoft said last month that Teams will blur QR codes sent by external senders to provide additional protection against phishing and fraud attempts.
- Bot blocking: In August Microsoft began rolling out a new Teams meeting protection policy that lets admins block all identified external bots automatically from joining meetings.
- Guest‑invite reporting: In September Microsoft announced that it will let users report suspicious guest invitations directly from Teams starting in November, a feature Microsoft positioned as helping security teams identify and block phishing attempts and other attacks abusing guest invitations.
What this means for technologists, procurement leaders, and end users
- Technologists and security teams: They will need to plan for integration of certified third‑party detection providers into Teams so detection signals are surfaced and acted upon inside meetings; they will also balance those signals with admin controls exposed via the Defender portal.
- Affected enterprises and procurement leaders: Organizations that buy meeting security services will evaluate vendors for certification and compatibility with Teams' signaling model and will weigh deployment timelines with Microsoft’s November general availability and the broader set of admin features announced across the year.
- End users and meeting participants: Users will begin to see in‑meeting warnings and risk indicators when Teams flags potential impersonation attempts and may notice changes such as blurred external QR codes or restrictions on guest joins as admins adopt the new controls.
Microsoft frames these changes as part of a broader move to boost security for Teams users by combining third‑party detection signals, identity‑focused warnings, and administrative controls. The immediate, concrete milestone is November, when both deepfake detection integration and impersonation protection are scheduled to reach general availability after a worldwide rollout — leaving organizations to prepare for the operational steps that follow.
