VPN Unlimited is available on most operating systems: it has applications for Windows, Mac OS, Linux, Android, iOS, Apple TV and Windows Phone and, additionally, browser plugins for Chrome and Firefox. There is no support for any operating system's built-in VPN connection feature, meaning that you will have to use their application to access their VPN servers. A welcome feature is that VPN Unlimited can be configured on supported routers, thus protecting your entire network (for this you need to purchase a Professional or Infinity plan).
KeepSolid's VPN service is available worldwide and, to make it work in countries where VPN traffic is throttled or blocked, you can enable the KeepSolid Wise feature, which masks your VPN connection as simple network traffic.
