Why Tessian?

Our approach to email security focuses on the core problem.

Preventing human error.

90% of data breaches start on email.

Email is an open gateway to your enterprise. It’s the most commonly used channel for targeted attacks and social engineering and it’s a major point of egress for sensitive data. The root cause of all of these threats is human error. Employees break the rules, make mistakes and can easily be hacked.To prevent today’s email security threats, your security controls must understand human behavior.

Secure Email Gateways and legacy email security controls rely on rule-based methods of threat detection and are unable to prevent security threats caused by people. Attackers evolve their techniques, email networks are dynamic in nature and human behavior is inconsistent and unpredictable meaning rules are out of date as soon as they are created and signature based approaches are completely ineffective.

To prevent today’s advanced email security threats, your security controls must have the ability to continually analyze, adapt and evolve based on an understanding of normal and anomalous human behavior. This is Tessian’s approach.
