EMAIL HEADER ANALYSER

Turn raw email headers into useful security evidence.

Headers can reveal how a message was authenticated, which identities it used and where it appears to have travelled. Jatzo brings that evidence into one assessment.

Evidence first.Clear result. Deeper detail when you need it.

Source IP context

Eligible plans can inspect public source IP evidence and supporting network context.
