If you are in the process of looking in to your online security then you may have come across the term VPN. VPN stands for Virtual Private Network and allow users to securely access a private network and share data remotely through public networks. This can mean that information you are accessing which may have been able to have been accessed by other people or your internet provider for example, no longer can thus making it more secure online.
If you happen to use your phone, tablet or laptop often on unsecured Wi-Fi networks such as in a café or in an airport then a VPN may be needed, especially if you are accessing your bank or other sensitive date for example. A VPN will encrypt your information before it reaches the public Wi-Fi making it more secure for you.
For some people they simply do not like the fact that the government and other companies such as their service provider can track what they are doing, this may include sites you are visiting, conversation you are having along with what you are searching for. For many people it is all about their own privacy rights and having a VPN allows them to only disclose information the wish to to the people they want to.
