Exchange & Exchange Online

Harden your Exchange security and alert on abnormal email activity.

Exchange servers can hold some of your organization’s most sensitive secrets. That, combined with the difficult task of safely configuring and monitoring Exchange Server and Exchange Online, makes email servers a primary target for attackers and insiders. 


Would you know if a hacker escalated privileges, read the CEO’s email, and marked messages as unread, and created an auto-forward rule? Compromised email accounts can be used for everything from social engineering to exfiltrating sensitive data to jeopardizing the security of an entire network.


With Varonis, you can detect sophisticated threats to Exchange and proactively reduce overexposure. Manage and reduce risk for both Exchange and Exchange Online with intuitive dashboards that highlight misconfigurations and anomalous activity.
