How does ZenMate differ from other plugins?

In contrast to many other plugins, ZenMate fully encrypts all your browser traffic.

Other plugins just work like a proxy that change your IP but do not offer encryption. ZenMate is the first plugin to offer real security and privacy by encrypting everything you do in your browser so that hackers and sniffing spooks (such as ISP's and governments) don't have a chance to get hold of you.
