Tessian further complements Microsoft Purview to prevent misdirected emails and stop email data exfiltration.

“Tessian complements Microsoft and reinforces our training. The platform stops the threats you just can’t make a rule for”
Mike Vieira, Cloud Security Lead, Schroders
Prevent Misdirected Email and Data Exfiltration

Tessian complements Microsoft Purview with an AI based approach to prevent messages from being sent to the wrong recipients, and sensitive data from leaving your organization. Leveraging an M365 add-in, Tessian provides a simpler experience for end users and admins alike.

Faster Email Incident Response

Performing hundreds of email investigations in Microsoft’s AIR and Threat Hunting tools can be a challenge. Tessian saves security admins time with one click search building and automated classification, triage and remediation for end user reported emails.

Coach end users in the moment

Coach users in-the-moment with contextualized data on the risks in their emails. Replace Microsoft’s generic banners to help users to learn quicker and understand their role in your defense.
