What is the primary purpose of data loss prevention (DLP) systems?

The primary purpose of data loss prevention (DLP) systems is to inspect and secure outgoing data. DLP solutions are designed to identify, monitor, and protect sensitive information as it is transferred outside of an organization’s network. This is crucial for preventing data breaches and unauthorized access to sensitive information, which can occur when data is sent via email, uploaded to cloud services, or otherwise transmitted outside the organization.

DLP systems employ various techniques and technologies, such as content inspection, contextual analysis, and policy enforcement, to ensure that sensitive data remains within the organization's approved channels and is not inadvertently or maliciously exposed. By focusing specifically on outgoing data, DLP systems help organizations safeguard intellectual property, customer data, and other essential information from potential leaks or theft.

This focus on outgoing data clearly distinguishes DLP from other security measures that may center on network traffic, device monitoring, or user access control management.
