Detecting data leakage to websites accessed using a remote browsing infrastructure

At least one non-transitory computer-readable medium comprising one or more instructions that when executed by a processor, cause the processor to:

• receive, by a remote browser isolation (RBI) proxy from a client device, a transfer request to send data to a destination application, wherein the client device is running an RBI agent and includes a Data Loss Prevention endpoint (DLPe) module, and wherein communications between the client device and the destination application are routed through the RBI proxy;
• receive, from the RBI agent, a plurality of inputs to the client device associated with the transfer request;
• create, by the RBI proxy, a submission request, wherein the submission request includes the plurality of inputs and associated metadata;
• send, from the RBI proxy, the submission request to the DLPe module;
• receive, by the RBI proxy, a response to the submission request, wherein the response includes an instruction to allow the submission request, to disallow the submission request, or to amend the submission request and allow the amended submission request;
• and
• process, by the RBI proxy, the submission request according to the instruction in the response.

• receiving, from the RBI agent, a plurality of inputs to the client device associated with the transfer request;
• creating, by the RBI proxy, a submission request, wherein the submission request includes the plurality of inputs and metadata identifying the client device and the destination application;
• sending, from the RBI proxy, the submission request to the RBI agent;
• making, by the RBI agent, the submission request available to the DLPe module;
• receiving, by the RBI agent, a response to the submission request created by the DLPe module, wherein the response includes an instruction to allow the submission request, to disallow the submission request, or to amend the submission request and allow the amended submission request;
• receiving, by the RBI proxy from the RBI agent, the response to the submission request;
• and
• processing, by the RBI proxy, the submission request according to the instruction in the response.
