Detecting impersonation attempts is essential

Many phishing attacks use sender impersonation to socially engineer their victims by adding credibility.

Cybercriminals have evolved their email impersonation attacks to get through Microsoft 365's native security functionality and secure email gateways (SEGs). This leaves it down to individual employees to determine which emails are legitimate and which are spoofed, with a single mistake exposing organizations to credential theft, data exfiltration, and fraudulent payments.
