Writing Style Analysis

Writing Style Analysis adds an additional layer of security to corporate email messages. It requires Cloud App Security to analyze and learn the specific writing style model for each required high profile user.

If Cloud App Security detects a suspicious incoming email message that does not match the writing style model of the supposed high profile user, it sends a copy of the original email message to the administrator of your organization for further manual verification.

Disabling this option prevents the original email message from being sent to the administrator of your organization, but severely affects/limits the ability of the administrator to understand the threat and take appropriate actions.

Data collected	Original email message
