Protect against accidental data loss

Stop misdirected emails

Tessian AI uses behavioral and content analysis to warn users of an incorrect recipient before the email is sent.

Prevent misattached files

Tessian automatically warns users when the incorrect attachment has been added to an email, helping them remediate in real-time before sensitive information is inadvertently sent to the wrong person.

Eliminate insider risk over email

Automatic content and recipient classification

Automatic detection of legal, financial, HR terms, and sensitive documents while discovering personal email addresses beyond freemail domains.
