Data Loss Prevention does not block or monitor data uploads to send.firefox.com

Technical Articles ID: KB91752
Last Modified: 12/22/2021

Environment

McAfee Data Loss Prevention (DLP) Endpoint 11.x

All browsers supported by DLP 11.x

For supported environments, see: KB68147 - Supported platforms for Data Loss Prevention Endpoint

Problem

DLP Endpoint does not block or monitor data uploads to send.firefox.com when you use a specific Classification in the Web Protection Rule.

Cause

The send.firefox.com website uses the Web Socket protocol. DLP Endpoint can only block access to this page based on the "Get" request. So, DLP Endpoint does not have the information of the file to store Evidences and does not act based on Classification.

Solution

DLP does not support uploads based on classification using the Web Socket. To get this feature in a future release, raise a Product Enhancement Request (PER).

NOTE: The Ideas forum replaces the previous Product Enhancement Request system.

Workaround

As a workaround to prevent data loss, configure the Web Post Protection rule to block or monitor "any data" uploads to the URL send.firefox.com/api/ws.
