That's the purpose of an EV cert, because it requires a company to prove its identity, so the very least you can do is to look for green bar / company name in the address bar.

So then why is it important? What is the argument for encrypting all web traffic? Does it act as a sort of camouflage for the actually important encrypted traffic?
