Business Email Compromise

Business Email Compromise (BEC)


The external tag is a feature Microsoft introduced to help customers recognize emails from external sources. This tag helps businesses, and their employees avoid falling into the trap of business email compromise (BEC). This tag will help you identify emails from attackers that are trying to spoof their email to resemble your domain. For instance, if your domain was, an attacker could send an email from, and if you didn’t notice the subtle difference you might click on a compromised link. Having the external tag eliminates the need to verify each email yourself as Outlook is now doing this for you. These types of attacks are growing extremely common, and this tool is an invaluable resource to prevent them.
