Digging a little into its history, ZenMate made its way into the marketplace back in 2014. This means it has been in the industry for a good 4 years. The provider has its main headquarters in Berlin, Germany – which is quite a safe location. Initially, the service was a FREE privacy extension for Chrome. However, later on it jumped the freemium bandwagon, creating premium plans too for leveraging better security.
Some VPN services provide a free trial, so take advantage of it. Make sure you are happy with what you signed up for, and take advantage of money-back guarantees if you're not. This is actually why we also recommend starting out with a short-term subscription—a week or a month—to really make sure you are happy. KeepSolid VPN Unlimited offers a one-week Vacation subscription, for example. Yes, you may get a discount by signing up for a year, but that's more money at stake should you realize the service doesn't meet your performance needs.
We like that the company offers a connection kill switch feature and, for those who need it, there's an option to get a dedicated IP address. VyprVPN is a standout in their effort to provide privacy, and thwart censorship. When China began its program of deep packet VPN inspection, Golden Frog's VyperVPN service added scrambled OpenVPN packets to keep the traffic flowing.
A “kill switch” goes by many names, but the term describes VPN software that shuts off all network traffic in and out of your computer if the encrypted connection fails. A hiccup in your Wi-Fi or even with your ISP can cause a VPN to disconnect, and if you then maintain an unsecure connection—especially if the VPN software doesn’t alert you that it’s no longer protecting your traffic—that wipes out all the benefits of your VPN. We considered kill switches to be mandatory. And although we looked for apps that made it easy to add rules about when to activate kill switches, we considered special config files or manual firewall tweaks to be too complex. (iOS doesn’t support any kill-switch features; we address a few iOS-specific problems that apply to all VPN services in a separate section.)
