DLP comes with a set of predefined expressions. After
DLP matches potential digital assets with an expression, the data
may undergo additional verification checks.
Expression Validators
Data units follow semantic rules. Not every 9-digit number is
a valid social security number and not every 15 or 16-digit number
is a valid credit card number. To reduce false positives, expression
validators check if the extracted data units follow these rules.
