New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


It is possible to fingerprint the remote mail server.


smtpscan is a SMTP fingerprinting tool written by Julien Bordet. It identifies the remote mail server even if the banners were changed.
