What is VPN in general:
VPN or „Virtual Private Network” was formerly used to securely connect to a private network over a public network. VPN encrypts the transfered data from your network card to the VPN server. The encryption is done in real time so nobody between can monitor your traffic. A VPN works fully independent from the used connection method. That means you can use a VPN anywhere, anytime on any device, over WiFi, UMTS or Ethernet. VPN fully encrypts the connection.
The potential of VPN technology was huge and so smart computer scientists found numerous ways to extend the use. One of these possible extensions is, to use it as a personal privacy shield.
To understand this, we need to take a look at the basic internet functions.
Access the internet without a VPN:
The process when you try to access a website. Broken down to the basics:
- Your computer asks a so-called “DNS server” where the website is, that you want to access. The DNS server creates the answer, sends it to your computer and saves the request for the future
- Your computer sends your inquiry to your ISP. They process and save your inquiry.
- Your ISP sends your inquiry to the Website you want to access. All your data runs through the infrastructure of your ISP. The webserver sends the file you wanted to access back to you. The answer also runs through all the infrastructure.
Now the problem should be obvious. At first, the DNS-server knows what you try to do. Therefore everybody who has access to this server can have a good insight into your browsing behavior. Secondly, all the data runs through the infrastructure of your ISP. Data, messages, and searchings are exposed completely. Thanks to that, your ISP knows exactly what you do. But there is an easy, quick and cheap way to secure your privacy. Using a VPN service.
Access the internet with VPN protection:
How this works:
Your computer encrypts all of your data with the chosen protocol and sends it to the VPN-server. We always recommend using OpenVPN here, since it is the safest protocol and yet fast enough. The data runs through the infrastructure of your ISP and the internet to our VPN server fully encrypted. Nobody on the way between can take a look at your data. The VPN server processes all the steps, your computer would have done. By that, all the computers, servers and internet devices only get to know the information about our server. Not about you. That means, the affected DNS server and the website you tried to access only know, that our VPN server accessed them. Your ISP only knows that there is data running through. But when they try to take a look at it, they only see encrypted, unreadable rubbish. By that, nobody knows what you are doing. To be absolutely safe, we always recommend a VPN provider that is completely log-free. That means the VPN-Server forgets does not track your online activities. Thus nobody can recognize, who was connected at which time with what outcome. The server forgets everything. By that, you become anonymous and nobody can trace your data.
The conclusion of that:
When looking for a VPN provider keep an eye on the following:
- Is not in a 14-eyes country
- Has a log free policy
- Is fast and reliable
