How Tessian Guardian Works

Intelligently Prevent Data Loss Without Rules or False Positives

Learn What ‘Normal’ Looks Like For Each Person

Tessian analyzes historical email data to understand content, context and communication patterns, enabling a comprehensive mapping of each and every employee’s normal behavior and email relationships (both within and outside your organization). Behavioral intelligence models are established and become more effective with each threat detected

Perform Real-Time Analysis of Emails Before They’re Sent

All emails leaving employee inboxes are analyzed in real-time. Using machine learning powered behavioral intelligence modeling, Tessian conducts an inspection of email content and attachments and automatically detects anomalous events that indicate accidental data loss.

Help People Correct Mistakes Before the Email is Sent

As misdirected emails and incorrect attachments are detected, end-users are alerted in real-time with clear, simple explanations and intelligent suggestions for alternative recipients. End-users are empowered to correct their mistakes before the email is sent.

Get Visibility into Breaches Prevented

With Tessian Cloud Email Security Platform, remediating and reporting on email security risks is easy. Warnings and employee interactions with those warnings are logged for inspection so you can create targeted policies or take other proactive and preventative action. Generate automated reports to share insights with other departments or the board.
