Why Use a VPN?
Updated: March 31, 2016
Why? Because a VPN does the following:
- Protects your online privacy
- Allows you access to geo-blocked online content/services
- Protects you against hackers
Why use a VPN? Well, because it connects you to the internet through a "private network", putting a layer of encryption on all your data and allowing you access to websites and online services that you would otherwise be blocked from accessing due to your physical location.
Lets look into each of these main VPN objectives in more detail to give a more well-rounded understand of what a VPN does and some context to how each purpose is executed and achieved.
Protects your online privacy
Using a VPN protects your online privacy. What does this mean? It means that the second you connect to a VPN, all of your online activity/behaviour is given a very sophisticated level of encryption that makes it incredibly difficult/impossible for your data to be connected to your identity and physical location.
A VPN does this by placing encrypted bits onto every packet transferred between your device and your ISP. Various protocols are offered to give varying levels of encryption, trading off less encryption sophistication for faster speeds and vice-versa.
Allows you access to geo-blocked online content/services
Geo-blocked online services and websites nowadays are becoming the norm. Everyone has experienced this in some way shape or form, whether with Netflix, Hulu or a YouTube video being blocked. These geo-blocks are 99% of the time implemented by checking your IP address, so through using a VPN you are able to change your IP address to "show" your location as wherever in the world you need to be to access the content you want at any time.
By allowing you control over your IP address, a VPN gives you the freedom to access online content you would otherwise be unable to access.
Protects you against hackers
Today's online monitoring and surveillance is pretty heavy and only getting more-so. Hackers are another level of this invasion. There are many third party individuals that purposefully use highly technically sophisticated methods to hack into your most sensitive online personal data such as bank details, passwords, private messages and even your device's microphone and camera.
With this going on, a VPN can act as a great base defence against such digital hackers. By allowing you to privatise your online connection through encryption and cloak your identity+location, you are instantly making it significantly more difficult for a hacker to access your sensitive data than without a VPN connection.
So all in all the main uses a VPN provides are privacy protection, IP address freedom, and hacker defence. Connecting to the internet through a VPN will give you these benefits instantly and consistently. A VPN is a simple, light piece of software/app that you download to your device(s), open, then connect to. They are easy to use and are becoming only more and more essential in today's online climate.
