VPN, or a virtual private network, is an Internet privacy technology that allows you to surf anonymously by encrypting all your online traffic at the IP level. In essence, VPN is a group of computers networked together over a public network (namely, the Internet). Businesses use VPNs to connect and use network resources remotely, when they're not physically on the same LAN, as a method for securing and encrypting their communications over untrusted public networks.
Anti-virus software and firewalls may protect the information on your computer, but a VPN is invaluable for protecting your data while online. Your IP address leaves a trace on every website you visit and reveals information about past websites you've visited, your ISP, and even your location. Even if you have not considered using a VPN, at some point in the future you probably should, and it may become as important as choosing an Internet provider if you value your privacy and the security of your online traffic.
More than 2 billion people are regular Internet users currently. Typically, this includes transferring some very confidential information such as banking info, business communications, passwords and general account data. What many people don't realize is that the majority of the time, this information is passed over a public and unsecured Internet. It's very easy, even for a novice, to set up programs to catch all this information as it passes over the open Internet (think "Free Wi-Fi" scams where travelers in an airport or cafe patrons fall victim to a fraudster's "free Wi-Fi hotspot" connection).
One simple and cheap solution to this is using a VPN, or virtual private network. This is a secured network that you sign into with your Internet-enabled device, which in turn encrypts and tunnels all your online traffic as it's carried over the public Internet. In short, it allows your computer or mobile device to send data over the public Internet as it were on a private, secure network, making it practically impossible for even the most sophisticated criminals to uncover your Internet traffic.
The most important aspect of VPNs
In short, a VPN secures your computer's Internet communications to guarantee that all of the data you are sending and receiving is encrypted and secured. It is a group of computers networked together over a public network. It allows you to get secure remote access to network resources over a public network, such as the Internet.
Sample VPN uses
Even if you do not specifically fit in any of the above categories, any combination of the above is a good reason to protect sensitive data online.
Additional Benefits of using a VPN
In addition to providing an encryption layer to pass all your Internet traffic through, VPNs offer a number of other benefits:
Bypass Region Restrictions - access blocked sites
As an end user, you should probably not worry much about the different encryption protocols (PPTP, L2TP,IPsec,SSTP, SSL/OpenVPN), as most of them have their benefits and drawbacks. It is probably enough to say that there have been some vulnerabilities found in the PTTP protocol, however, the most widely used ones are IPSec and SSL.
It is important to note that if you're planning on using VPN under different OSes, you should consider using SSL/OpenVPN, as OpenVPN works with Windows, Linux, Android and iPhone devices, unlike SSTP VPN, for example.
How to Choose a VPN Provider
There are many VPN service providers out there, and they all were not created equal. Many will try to throttle your speed and will limit you to the number of times you can switch IP addresses. The best VPN providers should offer most of the following list of key features:
It is probably worth mentioning that there are even some free VPN providers. A word of caution, however, is that free VPN providers have very weak commitment to your privacy, they offer fewer exit points, log your activities, serve contextual ads while you're connected, and track your usage to tailor future ads to you. All this defeats many of the key features in using a VPN service in the first place.
With all those considerations in mind, and short of rolling your own VPN, below is a list of some top VPN providers.
