My employer performs MITM on gmail.com by generating their own certificate authority. I've only noticed this applies to the web version of Gmail. In additon, Chrome on Windows will alert me when the certificate is not completely authentic.
Does this also apply to the Android App? Will the same MITM logic for gmail web work on the Android App, or is the app more secure? Note that I do not get the same certificate warnings on the app. It's hard to tell if my traffic is intercepted via the app. Are there any other methods that could be used to intercept and decrypt traffic from the Gmail android app?
