A Data Loss Prevention (DLP) template combines DLP data identifiers and logical operators (And, Or, Except) to form condition statements. Only files or data that satisfy a certain condition statement will be subject to a DLP policy.
For example, a file must be a Microsoft Word file (file attribute) AND must contain certain legal terms (keywords) AND must contain ID numbers (expressions) for it to be subject to the "Employment Contracts" policy. This policy allows Human Resources personnel to send the file to recipients within a domain. Sending the same file to recipients outside the domain is blocked.
You can create your own templates if you have configured data identifiers.
