Tessian Defender FOR INBOUND EMAIL

Prevent email threats that legacy email controls can't detect.

Automatically prevent spear phishing, business email compromise, and other targeted email attacks.
  • Essential defense against today’s inbound security threats.

    Even the most savvy employees can fall victim to the modern social engineering and spear phishing attacks of cybercriminals. Automatically prevent unsafe emails and protect your employees and your data to maintain customer trust.

  • Fix the gap in your email security strategy.

    Tessian can capture difficult-to-detect domain spoof manipulations, zero payload attacks, and look-alike impersonations of internal and external contacts that are impossible to detect with Secure Email Gateways and legacy email security controls.

  • Secure every email while educating your employees.

    Tessian Defender adds intuitive warning banners to unsafe emails which immediately alert employees to potential risks and reinforce security and awareness training.

How Tessian Defender works
Establish employee relationship graph using historical email data.
Tessian analyzes historical email data to understand normal content, context and communication patterns, enabling a comprehensive mapping of every employee’s trusted email relationships (both within and outside your organization). Relationship graphs are established and continuously updated as email behaviour changes over time after Tessian is deployed.
Perform real-time analysis of inbound emails.
Tessian’s Human Layer Security Engine analyzes all inbound emails in real-time and uses machine intelligence to automatically predict whether the email looks unsafe based on insights from the relationship graphs, deep inspection of the email content and previous user behaviour.
Automatically prevent targeted email attacks.
When unsafe emails are detected, employees can either be alerted in-situ with clear, simple explanations of potential risks or emails can be directly quarantined for inspection and approval by Security Analysts.
