The Data Loss Prevention policy monitors content for Personal Information Identifiers (PII) based on the policy's rules configured. A PII is any personal information that may identify an individual; for example, financial account numbers, medical records, passport or government identification numbers, or credit card numbers.

Data classifications are groups of PII combined for the purpose of monitoring similar content. For example, you can create a Data Classification that encompasses medically related PII by including the built-in identifiers for ICD codes, drug names, prescription names, health conditions, and national drug code names. The classification, when applied as a rule to the Data Loss Prevention policy, will monitor and block content matching these identifiers.
