Overview

Tessian is an email security company that uses machine learning to understand human behavior and prevent security threats caused by human error. Its platform analyzes historical email data to understand normal communication patterns and relationships. It then detects anomalies that could indicate threats like business email compromise, accidental data loss (e.g., misdirected emails), and data exfiltration. Tessian's approach is to protect people where they are most vulnerable - on email.
