How do you know that my data is public?
OK - let's clear this up first before we go into what a VPN (Virtual Private Network) is, and how to protect your data by using one.
So how do I know your data is public? Well, I don't know that it is public in the way that this blog is public, but I do know that it could be, and very easily.
How would that happen? Well, it would just take the will of one of the many millions of capable hackers from anywhere in the world. Every day there are breaches of privacy and data that harms innocent users of the Internet. They are able to, once having peered into your stream of data, they can see everything you do, and get information on things like payment information, banking information, all documents, emails, and literally any ingoing or outgoing, sensitive information. This information can be used to do a load of harm, like wiping bank accounts clean, stealing personal identities, and releasing information that could be damaging if made public.
Is there a way to protect my data and browse the Internet privately?
The simple answer is yes, and yes.
And the simple solution is to go buy a VPN service.
What is a VPN (Virtual Private Network), and how does it work?
A VPN is a system that allows your connection to be hidden behind an extremely sophisticated system of encryption. Just like with everything else on the planet, there are good VPN systems, which typically cost more money, and there are bad VPN systems, which can be as low cost as FREE (the FREE ones don't actually work. If you look into this, you will soon discover that this is true).
The ones that work go through the process below where they are in between your device and the Internet, and they go through a process of cloaking your IP address, blocking unwanted connections, and encrypting all data going in, and coming out, which all allows you to browse anonymously, and safely.
Go get one. I won't make any suggestions because I've only tried one. Go out there and do some research. I think you will find that the prices are reasonable, the options are good, and that the benefits make having a VPN very worth trouble and service fees.
