What is the primary function of data loss prevention (DLP) technologies?

The primary function of data loss prevention (DLP) technologies is to monitor and manage data during transactions, ensuring sensitive information does not leave the organization's environment without proper authorization. DLP solutions are designed to identify, monitor, and protect data in use (in endpoints), data in motion (in transit), and data at rest (stored). By doing so, organizations can prevent accidental or intentional data leaks, safeguarding sensitive information such as personal identification information, financial records, and intellectual property.

Monitoring data during transactions allows DLP systems to enforce policies that prevent unauthorized access and sharing of sensitive information. This aspect is crucial for compliance with various regulations and standards, such as GDPR or HIPAA, which mandate the protection of personal and sensitive data.

In contrast to the other options, which do not capture the core purpose of DLP technologies, the focus of monitoring data transactions is intrinsic to DLP's role in protecting against data breaches and ensuring that organizational policies regarding data security are upheld.
