About Data Identifier Definitions

NOTE: Data Identifiers are legacy DLP features that will no longer be supported by the end of June 2025, it is recommended to use a classification-based approach for all your DLP use cases. To assist with migrating your DLP policies from Data Identifiers to Classification, refer to the Migration Guide.

DLP Policy Rules use Data Identifiers to recognize potentially sensitive information in your files and messages. For example, Social Security Numbers, Credit Card Numbers, and other personal identifiable information can use advanced validation to improve accuracy. (For example, Data Identifiers can validate the Luhn check for credit card numbers.)

The following topics provide definitions, validation, and keyword information for all supported data identifiers.
