Advanced Email Security Protection for Office 365

Threat actors target Office 365 infrastructure with identity deception.

Microsoft Office 365 is the dominant choice for large organizations using or considering cloud-based email. While the move to Office 365 reduces operations and management overhead and provides a compelling user experience, it raises serious security challenges. If you’re making the move to the cloud and Office 365, you need to augment your email security to address today’s most damaging threats.

Office 365 Security Is No Match for Identity Deception

Email is the preferred cyber-crime attack vector and the entry point for 95% of the world’s breaches*. While Office 365 provides good enough security to stop spam, known viruses and malware, it won’t secure you against the most sophisticated email attacks such as Business Email Compromise or spear phishing that rely on identity deception.

In fact, identity deception is so effective that it is used in nearly all advanced email attacks. To stop these attacks a new model focused on determining sender trust and message authenticity is required, of which Exchange Online Protection was never designed for.
