Issue/Introduction

As an administrator, I would like to block downloads/uploads when using Web WhatsApp. The chats need to remain active and working.

Environment

Cloud Secure Web Gateway (formerly Web Security Service)

Cause

Web WhatsApp is accessed through the URL web.whatsapp.com, files download and upload is done using the URL mmg.whatsapp.net.

Resolution

UPDATE:

The domain mmg.whatsapp.net. is now being used to access Web Whatsapp initial login, therefore, blocking download and upload while loading the application is no longer possible.

You will need to block the entire Web App called Whatsapp

  1. Create a Content filtering policy under Group B and add a policy with the Web Whatsapp application, set to Block
  2. Additionally, another rule can give create to give specific users access to the application. The rule needs to be placed above the block.

 Note: If you are using Universal Policy Control (UPE). You will need to create a policy for these domains under the web access layer using VPM.
