Email/Spam filtering adds an additional layer to protect your business against potential breaches. Incoming and outgoing emails are scanned for known attack vectors and blocked before they are delivered.

A common method used to infiltrate email is to alter where the email was sent from, this can be made to look like the email was sent internally.
An easy approach to safeguard against this is to configure emails to have a label which show if it was sent from an Internal or external sender. Once configured each email will then clearly show if the email was sent from outside your business and helps prevent this common attack vector.
