Abstract
Embodiments of the present disclosure describe systems, methods, and computer program products for redacting sensitive data within a database. An example method can include receiving a masking policy for a column of a database, the masking policy identifying a category of sensitive data, examining a column of a database to identify a category of sensitive data in a first location of the column, and, in response to a data query accessing the column, the first location of the column exceeding a threshold probability of comprising sensitive data, executing a redaction operation to redact the category of sensitive data from the first location of the column to generate redacted data for a response to the data query.
