Microsoft Teams to Support Third-Party Deepfake Detection and Impersonation Protection
Microsoft Teams will add support for certified third‑party deepfake detection solutions and an impersonation protection feature, slated for general availability in November. The update will surface alerts for synthetic media and suspicious meeting hosts, enabling defenders to act on detection signals.
What Happened
Microsoft announced that Teams will integrate third‑party deepfake detection services and an impersonation protection feature. The changes are in development and will be GA in November after a global rollout.
Organizations can enhance meeting security with synthetic audio and video detection solutions provided by certified third‑party providers.
Impact
All Teams users in organizations that adopt the feature will receive in‑meeting alerts when synthetic audio/video or potential impersonators are detected. The feature relies on certified providers that send detection signals to Teams.
What to Do
- Verify that your organization’s Teams admin has enabled the new security settings once GA.
- Review the list of certified third‑party providers and evaluate integration for your environment.
- Configure Teams to surface risk indicators and warnings for suspicious meeting hosts or participants.
- Train staff to recognize the new warning messages and to verify identities before joining a meeting.
- Monitor Teams logs for detection signals and investigate any flagged meetings.
Mitigation Guidance
Enable the impersonation protection toggle in the Teams admin center. Set up alerting for detection signals and integrate with your SIEM for automated correlation. Keep the Teams client up to date to receive the feature as soon as it becomes available.
