The first runs in the VPN client app on your computer, so if the VPN connection fails while the VPN client app is running, that VPN client app can turn off the computer or mobile device's internet connection. However, if your VPN connection has failed because the VPN client app itself crashed, then the kill switch may not work, and your IP and data may leak onto the internet.
Even TunnelBear's network performance and pricing are just about average compared to other services we've reviewed, except that you can pay with literal jars of honey. The company takes security and privacy seriously, explaining its policies and protocols in plain English, and you can read the results of two third-party security audits on the company website.
The second thing that happens is that the web application you're talking to does not get to see your IP address. Instead, it sees an IP address owned by the VPN service. This allows you some level of anonymous networking. This IP spoofing is also used to trick applications into thinking you're located in a different region, or even a different country than you really are located in. There are reasons (both illegal and legal) to do this. We'll discuss that in a bit.
Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We're pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors' Choice nod both for desktop VPN apps and Android VPN apps.
Chosen as one of Mashable's top three for staying anonymous online, NordVPN is a choice backed by much of Reddit. It's made for fast streaming and torrenting, P2P and non P2P options, and is one VPN that can actually bypass the American Netflix block anywhere in the world. Plus, a single NordVPN login can be used on up to six devices simultaneously, so sharing the perks and splitting the price is a major bonus for savvier internet users. Reddit user ambillop writes:

For features, VPN.ac offers double-hop VPN servers, numerous encryption options, obfuscation (stealth VPN), and great apps for all major operating systems and devices. VPN.ac’s apps are very well designed and come in both light and dark modes. In addition to the VPN, you can also use their secure proxy browser extension, which is available for Firefox, Chrome, and Opera browsers.
The service uses Advanced Encryption Standard with a 256-bit key, a common method employed by VPN services. Connections are protected using 2048-bit public key encryption. For privacy, the service offers a malware detection software. What is good about the software is that it can be downloaded and used without providing any personal information. This holds as long as you use the free version of the software and never contact customer support.

A powerful VPN service, Hotspot Shield is ideal for those who enjoy using public Wi-Fi. It is basically a free VPN that comes in the form of an application or as a browser extension. Security is assured as the service uses OpenVPN , which makes use of the same encryption as HTTPS does. This feature is particularly effective in protecting credit card information during online purchases.
In terms of general performance, Hide My Ass! around the average mark with a quick and stable 6.4MB/s (51.2Mbit/s) for FTP to 6.9MB/s (55.2Mbit/s) HTTP via UK endpoints, and 8.8MB/s (70.4Mbit/s) for FTP and 7.2MB/s (57.6Mbit/s) HTTP in the Netherlands. In other words, pretty good going. VPN connections to the U.S. are almost invariably slower than those to closer geographic endpoints, as you’d expect, the 2.12MB/s (16.96Mbit/d) we got with Hide My Ass this time around was definitely below average.
Obfuscation – Obfuscation is a key feature if you are using a VPN in China, schools, work networks, or anywhere that VPNs may be blocked. However, if you are not in a restricted network situation, obfuscation is generally not necessary and may impact performance. (See the best VPN for China guide for a great selection of VPNs with built-in obfuscation features.)
The Overplay Smart DNS service, on the other hand, routes internet connection using a different DNS to give the illusion that one is located in a different country, without significant speed reduction. This is very useful to those who want to access sites that are blocked in their own countries. The service supports PCs, Apple TV, iPhone, iPad, Wii, PS3, XBOX360, among other devices.
Buffered VPN doesn't disclose much about the size of its network, but the 30-day money back guarantee means that you can take their service for a test drive and really get a feel for how well it performs for you. The company lost a few points from us because they do keep some connection information. They gained points for their client support, unlimited bandwidth, and generous number of simultaneous sessions allowed.
