The Opera browser for Windows and OS X comes with a free built-in VPN, the first of its kind. The service has no data limits and can be activated through the settings. Activating it will incur some performance penalties and the only locations it supports are Canada, U.S., and Germany. Opera was acquired by a Chinese company, but SurfEasy, a Canadian company independent from the Chinese conglomerate, provides the VPN service. The drawback of the Opera VPN is that it won’t cover your non-browser traffic, such as your email or FTP client applications.
