Which Microsoft Defender feature is designed to detect impersonation attempts?

The feature designed to detect impersonation attempts is Anti-phishing protection. This capability is specifically geared towards identifying and blocking phishing attacks, which often involve an attacker posing as a trusted individual or organization to manipulate victims into divulging sensitive information, such as usernames, passwords, or financial details.

Anti-phishing protection utilizes machine learning and various detection techniques to analyze incoming emails and messages, looking for signs of impersonation, such as discrepancies in sender information or unusual language patterns. When potential impersonation is detected, it can alert users and initiate protective measures, such as quarantining the email or blocking the sender. This proactive approach helps organizations safeguard sensitive information and enhances overall security posture against common cyber threats.

In this context, other options like Threat Explorer, Threat Trackers, and Threat Response focus on different aspects of threat detection and management but do not specifically address the identification of impersonation attempts as effectively as Anti-phishing protection does.
