What is a VPN?

A VPN, in a nutshell, anonymises your online browsing by encrypting any data that you might enter as well as shielding your location and IP address from view. This means that in theory your actions are completely untraceable and it prevents any prying eyes from having access to information you would rather keep to yourself. You can use a VPN on a laptop, desktop or mobile and it doesn't matter who your broadband provider is.

How does a VPN work?

When you log onto the internet via a VPN, your internet connection is routed through multiple different servers. Any information shared as a result of your browsing is then hidden from view from anyone who might be watching, including your service provider. If somebody was trying to snoop on you when you were looking at their website they would only be able to see the IP address of the VPN provider rather than your own as you are using the secure network that the VPN provides.

Why should I get a VPN?

The main reason that people are drawn to a VPN is, as you’ve probably guessed, privacy. There are growing concerns around internet security and a VPN offers an additional level of safety on top of any spyware or antivirus software you may have.

A VPN is especially useful if you are someone who connects to public wi-fi. These hotspots are far less secure than home networks which means that it’s far more important to make sure your data is encrypted.

The anonymity of a VPN also prevents any targeted ads and stops your data being harvested and sold on for profit.

Are there any downsides to getting a VPN?

If you decide to opt for one of the more secure VPNs then you will have to pay, but they are rarely more than £10 a month, so it shouldn't break the bank.

The noticeable downside when you're using it will be your internet speed. As the VPN diverts your connection through their own servers, the increased output slows down the connection speed. Different VPNs will be able offer different speeds, so it’s worthwhile checking the specs before you buy one.
