If VPN connections get blocked by your network because of strict network management or government censorship, TorGuard offers a “stealth” connection to avoid deep packet inspection. Specifically, TorGuard uses Stunnel (a clever portmanteau of SSL and tunnel) to add an extra layer of encryption and make your traffic look like normal, secure Web traffic. If you’re having connection issues, you can enable Stunnel with a checkbox on the main application window, but only if you select TCP from the protocol list. (Otherwise, the box is unclickable, with no explanation as to why.)
Instead of logically tying the endpoint of the network tunnel to the physical IP address, each tunnel is bound to a permanently associated IP address at the device. The mobile VPN software handles the necessary network-authentication and maintains the network sessions in a manner transparent to the application and to the user. The Host Identity Protocol (HIP), under study by the Internet Engineering Task Force, is designed to support mobility of hosts by separating the role of IP addresses for host identification from their locator functionality in an IP network. With HIP a mobile host maintains its logical connections established via the host identity identifier while associating with different IP addresses when roaming between access networks.
Websites using Google Analytics and various advertising networks can very well track and identify visitors based on a variety of different inputs with their browser (see browser fingerprinting). Therefore it’s best to use a VPN in conjunction with a secure browser configured for more privacy. See my guides: secure browser (an overview of different browsers) and also Firefox privacy, which deals with privacy configurations, tweaks, and add-ons.
In this case, agencies see only the tunnel and not what is inside. They only get to view a single connection from a specific server and not who the user is, location or what is being downloaded or uploaded. VPN software also has the ability to provide agencies with user information or deny request for such. Such solution can be implemented as client and server software, hardware and software or on a subscription basis. There is also Secure Sockets Layer VPN, which enables remove users to connect by simply using a web browser.
If you need a more affordable VPN than our top pick and don’t have an Apple device—or if you need ChromeOS support—we recommend TorGuard. Its apps aren’t as simple or user-friendly, but TorGuard is a good option for more tech-savvy people or those willing to spend a little more time fiddling with an app. TorGuard’s CEO has built trust by talking with media outlets (including us) and detailing the company’s commitment to a service built around a lack of activity logs. Though the apps aren’t as easy to use as our top pick, the connections were the fastest of any we tested and the company has more than twice as many server locations.
To choose the best VPN for you, don’t just look at the price, not least because many services offer massive discounts if you take out a longer term subscription. Start with the basics: how many simultaneous connections can you have? Are there particular security protocols you want to use? Does the provider have servers in the places you’ll want to use it from and the places you want to connect to? How much data will they log about you, and how long do they keep it for?
CyberGhost has been around since 2011 and has come out strongly as a supporter of "civil rights, a free society, and an uncensored Internet culture." We really liked how the company specifically showcases, on their Web site, how folks normally prevented from accessing such important services as Facebook and YouTube can bring those services into their lives via a VPN.
