Detect sensitive information

The main feature of the Proactive DLP engine is to detect and block sensitive data in files, including credit card numbers and social security numbers. The engine supports a wide range of file types, including Microsoft Office documents and PDF.

Sensitive Data

• Social Security Number (SSN, US and JP)
• Credit Card Number (CCN)
• IPv4
• Classless Inter-Domain Routing (CIDR)
• Any specific data pattern using the regular expression
• _Note: Defining so simple regexes is not the recommended way to use this engine, For example: \d , \w. _Because most documents contain many numbers, so the complexity and time needed to scan are going to be increased a lot when you define something so simple. Turning redaction on with this regex would cause even worse performance.

Certainty score

Certainty score is defined by the relevance of the given hit in its context . It is calculated based on multiple factors such as the number of digits, Bank Identification Number (BIN) lookup, context ...
