What is the primary function of an Endpoint DLP System?

An Endpoint Data Loss Prevention (DLP) system primarily focuses on preventing unauthorized data transfers or leaks from endpoint devices, such as desktops or laptops. Its main function is to identify and stop the transfer of sensitive information, whether through email, USB drives, or other means, and to notify administrators of such attempts. This capability ensures that confidential data remains secure and is not incorrectly shared or compromised.

While monitoring data in transit and inspecting data at rest are important aspects of a broader DLP strategy, they do not specifically highlight the role of endpoint DLP, which is distinctively focused on activities directly involving endpoint devices. Protecting cloud-stored data, on the other hand, often falls under the purview of cloud security measures rather than endpoint protection. Thus, the primary function of an Endpoint DLP system is effectively to stop file transfers that violate security policies and alert administrators to potential data breaches or compliance issues.
