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 behaviour.

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email networks are dynamic in nature and human behaviour is inconsistent and unpredictable meaning rules are out of date as soon as they’re created and signature based approaches are completely ineffective.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 analyse, adapt and evolve based on an understanding of normal and anomalous human behaviour. This is Tessian’s approach.

Tessian turns your email data into your biggest defense against email security threats. We call it Human Layer Security.

Your Data

Your email data is an invaluable source of threat intelligence.

Your employees communicate with their network (internal and external contacts) over email. They have specific project relationships with each person in their network.

Employee project relationships, context, and networks are constantly refreshing with every new email, every new project, and in tandem with business needs.

There’s a wealth of information behind each email communication that can inform behavior, provide context to detect threats unique to your organization.

Through a combination of machine intelligence, deep content inspection, and stateful mapping of email relationships, Tessian turns your email data into your best defense against email security threats.

STEP 1: Establish and Update Normal Behavior
STEP 2: Real time analysis and detection
STEP 3: Threat prevention

Tessian analyzes historical email data to understand normal content, context, and communication patterns for every single employee in your organization. Relationship graphs are established and continuously updated as email behavior changes over time after Tessian is deployed.

Tessian analyzes all inbound and outbound emails in real-time and uses machine intelligence to automatically detect if emails contain security threats based on the Tessian Data Layer, Content X-Ray and Behavioural Analytics insights.

As security threats are detected, employees are alerted in real-time with clear, simple, contextual explanations.
