Data Loss Prevention (DLP)
Tools and policies that detect and block sensitive data from leaving an organization's control, whether by accident or theft.
DLP systems monitor email, file transfers, cloud uploads, and removable media for patterns matching sensitive data (like credit card numbers, health records, or classified documents) and can block, quarantine, or flag transfers that violate policy. It addresses both accidental leaks (an employee emailing a spreadsheet to the wrong address) and deliberate exfiltration.
