How Tessian Guardian works

Establish employee relationship graph with historical email data.
Tessian analyzes historical email data to understand normal content, context and communication patterns, enabling a comprehensive mapping of every employee’s email relationships (both within and outside your organization). Relationship graphs are established and continuously updated as email behavior changes over time after Tessian is deployed.
Perform real-time analysis of emails before sending.
Tessian’s Human Layer Security (HLS) Engine analyzes all outbound emails in real-time and uses machine intelligence to automatically predict whether the email will result in accidental data loss. HLS engine uses insights from relationship graphs, deep inspection of the email content and attachments, and previous user behavior to detect these anomalous events and gives organizations control over email data.
Automatically prevent accidental data loss from misdirected emails and misattached files.
As misdirected emails and incorrect attachments are detected, employees are alerted in real-time with clear, simple explanations and precise reasons for anomalies and correct recipients are suggested. This way, they can correct the recipient(s) and review attachments before the email is sent. Employee interactions are also logged for inspection in the Tessian dashboard.
