Teams adds bot checks and security reports for admins

Before this, admins often had to manage meeting bot risk through meeting etiquette, app approvals, and scattered security signals. In sensitive calls, one accidental bot admission can create a privacy problem long before anyone opens a compliance report. The useful change is that Teams is moving more of this risk into admin-visible controls and reports. Small Microsoft 365 teams still need policy decisions: which meetings tolerate external bots, who can approve them, and who reviews Teams security detections when suspicious messages or files appear.
