Microsoft has introduced a Brand Impersonation Protection feature for Teams that scrutinizes incoming VoIP calls from unfamiliar external contacts to identify potential brand impersonation. This feature alerts users to high-risk and suspicious calls, aiming to enhance security in digital communications. Additionally, Microsoft has postponed the rollout of its Wi-Fi location tracking feature to mid-March, which monitors users' live locations when connected to office Wi-Fi, raising concerns about corporate surveillance.
