when connected to a corporate vpn or in a corporate wifi environment, the corporation network uses a proxy for all http traffic. When connect to a personal wifi and not connected to the corporate vpn, all internet connection will display a page where it says "please connect to corporate vpn before you can visit any website". There is a McAfee root CA also being added to the system that allows this to happen. How does this work behind the scene?
the deployed service to client laptop is called McAfee SaaS Web Operations, I just wonder how it works to make root CA redirecting traffic
