Preventing human error: Solving misdirected emails on Microsoft 365

Email has the highest risk of data loss - more than any other form of business communication. In fact, 91% of organizations experienced outbound email data breaches in their Microsoft 365 environment in the last year.

Human error is virtually impossible to prevent using traditional static DLP rules and solutions, which are too rigid to effectively prevent data loss caused by human error over email.
