vishing protection

Vishing protection refers to defenses against voice phishing, where attackers impersonate trusted entities over phone calls to steal sensitive information. Microsoft Teams has introduced a brand impersonation protection feature that automatically scans inbound VoIP calls and warns users when a call appears to be spoofing a legitimate brand. This client-side shield extends Teams' existing anti-phishing controls into the calling channel, helping to mitigate vishing and social engineering threats. The feature is part of Microsoft's broader effort to harden Teams against malicious calls, links, and file types, providing an additional layer of security for enterprise users.
