Microsoft Defender for Office 365 provides enterprise email accounts with automated attack remediation and defends them from various threats, including business email compromise and credential phishing.

Some security controls are inadvertently overlooked, and as a result some or all users are left with incomplete protection,Not turning on these key protection features can lead to unintentionally allowing malicious messages, such as phishing messages, to be delivered to their inbox.

Once enabled, it will protect all existing and new end users across tenants from phishing emails with malicious attachments and links using Safe Attachments and Safe Links without requiring any actions from admins.
