Reduce the burden on SOC teams by automating triage, investigation, remediation and risk reporting. Fully automated by machine learning, Tessian requires no manual rules or policy configurations.

Makes phishing awareness training stick by alerting end users to threats in-the-moment with contextual warnings that help them spot threats in the future. Low false positive rates means when they see an alert, they pay attention.

Tessian Defender is a comprehensive advanced email threat prevention solution that automatically prevents a wide range of attacks that bypass Secure Email Gateways, while providing in-the-moment security awareness coaching to drive end-users toward secure email behavior.

Email security is no longer limited to securing an organization’s own email platform. There is a growing trend where attackers gain access to the email account of a trusted sender, impersonate the sender and use it to conduct fraudulent activities.
