Systems and methods for Zero-day Data Loss Protection (DLP) having enhanced file upload processing are provided. One method may include capturing and sending file upload context (e.g. folder name, metadata, an active URL, etc.) associated with the scheduled file or folder upload to a DLP filesystem driver. For example, the method may include detecting whether a single/multi-file upload, a folder upload, or a drag-and-drop operation exists, through interception of the shell dialog API, the browse folder API, or the drop process interface, respectively. Further, the method may include generating a file upload cache including the file upload context, prior classification entries, and a timestamp indicating when the scheduled file or folder upload was last modified; such that, the DLP filesystem driver may intercept and process the file open call based upon the file upload cache. Accordingly, the file may be processed in accordance with a prior file classification, file/domain filter, or DLP policy.

The disclosed computer-implemented method for preventing data loss over virtualized networks may include (1) receiving, by a data loss prevention callout driver registered to a switch, a network packet from a virtual machine, (2) identifying, by the data loss prevention callout driver registered to the switch, flow context information that specifies a context associated with transmitting the network packet, (3) providing the flow context information and the network packet to a data loss prevention service, and (4) applying, by the data loss prevention service, a data loss prevention policy to the network packet based on the flow context information. Various other methods, systems, and computer-readable media are also disclosed.
