Why it matters
Uninvited AI meeting agents joining sensitive discussions are a real data-exposure vector, and this vendor control shows how platforms are trying to gate agent access to enterprise collaboration.
The Register reports that Microsoft is rolling out bot-detection technology for Teams meetings that uses behavioral and infrastructure signals to distinguish bots from humans, requiring a human in the lobby to deliberately admit a bot. The move responds to unwanted bots—including third-party transcription and meeting-assistant bots—automatically joining meetings that may involve sensitive or NDA-covered discussions, and will add an ISV registration path for known bots while retiring CAPTCHAs.
