What is a VPN? And why you should Choose a VPN
What is a VPN?
VPN stands for ‘Virtual Private Network’ when it is not shortened to VPN it makes more sense. Its name itself is somewhat accurate and descriptive of its function.
The ‘Private’ part of its name is most important as it describes the key benefit of a VPN over a Proxy or a Smart DNS. VPN providers encrypt all traffic transferred across their networks, usually with 128bit or 256bit encryption and connected by one of the following protocols; PPTP, OpenVPN, L2TP/IPSec or SSTP. The encryption means that ISP’s, Google, Facebook, Governments, Hackers and the NSA cannot see what you are getting up to online. Your normal connection to the internet provided by your ISP is not encrypted and leaves you vulnerable to unwanted spying, so you should always be trying to connect to a VPN – even if you’re just browsing.

Let’s now look at ‘Network’ – VPN providers have servers placed in lots of different countries around the world, this creates a ‘Network.’ The VPN provider allows you to connect to their network of servers and use them to securely and anonymously browse the internet.
The last piece of the puzzle is ‘Virtual.’ By connecting to one of the servers in the VPN providers network your computer/device appears to the outside world as if you are the server in whichever country/location you have chosen. Therefore you ‘virtual-ly’ appear to be somewhere that you are not.
Why Choose a VPN
There are many reasons that you should you use a VPN. Not only for anonymous online, but it also provides a layer of protection that you do not get with any other type of security software.
There a numerous horror stories of people bank accounts, social security numbers, facebook accounts being hacked and most of the time this can be avoided. Most hackers can obtain your data over an unsecured connection or public Wifi. By using a VPN, you create an encrypted tunnel between your device and the website you are connecting to – any data that the passes through the tube are entirely invisible to any would-be hacker.
One of the most common uses for a VPN is to allow users to stream multimedia content that would otherwise be restricted to their location. A VPN enables you to appear somewhere that you are not by changing the IP address that the rest of the world can see. Once your IP address is broken, you can access previously unavailable content.
