Categories are arbitrary strings
that can be used to define your scan (targets, type of
scan, etc.).
Example: Country-XX,Standard
,
or AS-12345,Fast
.
If you
are authenticated, your username will be set as a
category in addition to thoses specified. If you
decide to share those results with other users of this
instance (see below), the category "Shared" will be
set in addition to thoses specified (and if you
include a category "Shared", the results will be
available to other users of this instance, regardless
of "Make the results public").
