What Is VPN – Purpose, Principle Of Operation And Advantages Of VPN


The abbreviation VPN stands for Virtual Private Network, VPN is a technology that provides an encrypted connection and works over the Internet. You can connect to it from anywhere in the world. VPN allows you to anonymously browse sites blocked in a particular region. In simple terms, a VPN is a secure technology that will allow you to bypass legal and geographic restrictions while using the Internet.

Why Is It Needed

The legislation of some countries provides for blocking the list of sites, although for most citizens of these regions they do not bear any harm. Often such web portals are used for entertainment purposes, and sometimes for educational purposes.

How VPN works

VPN technology is most often used in cases where the IP address of the user’s computer does not have access to certain sites.

After starting VPN, using a browser extension or a special program, the IP address changes to the IP server of another country – France, Germany, Great Britain or any other. Start your VPN free trial and get connected to the world without any restrictions.

Eventually, if you decide to get a paid version, there are providers on the market that offer great VPN deals and coupons – so you can save great discounts when purchasing.

Once connected to a private network, a secure connection is created that cannot be blocked by the ISP. This allows you to anonymously browse any sites on the Internet, even if they are blocked in a particular region.

What is the catch of free VPNs

Everyone wants to make money on the services they provide. Developers of VPN programs and browser extensions are no exception.
