Does Symantec DLP perform detection based on keyword proximity to a pattern?
No. Symantec DLP does not perform a proximity check in the default DIs (in other words, data that appears within close proximity of each other, or a specified vicinity of a set number of words).
The keyword validator has to be within the same document / component (i.e., header, body, attachment). For example: The DDI will not trigger on a keyword in the subject line (part of header) when the specified keyword is in the body of an email.
