VPN: what is it?

The term: “VPN” often appears in the context of corporate data transfer security. This type of technology is a good solution not only for IT or corporate employees, but also for ordinary users. Choosing a VPN is proof that we are serious about network security. How does this technology work?

About VPN increasingly can be read in the media, blogosphere in the context of protecting Internet user’s privacy. And although the beginning of the existence of the virtual network is related to business, not only entrepreneurs need it. VPN originally was created to protect correspondence from industrial espionage.

What is VPN?

A VPN (Virtual Private Network) is a virtual private network in which all data between the user and the network is transmitted through an encrypted tunnel. VPN features:

• the user connects to the Internet through a special server
  intermediary, so that the data is confidential and fully secure
• this network does not physically exist and works as
  virtual bridge connecting user and server
• A VPN is a private connection, that is, the user has
  access to an account where he or she enters login information, i.e. a login and password.

The operation of VPN is very simple: when a user connects to a server, a connection is made between the server and the Internet.

What is VPN protection all about?

The VPN sends data in encrypted form. This involves assigning a new IP address by the VPN server, through which the user connects to the Internet. The real IP address is invisible and there is no way to access it. It is possible to connect to VPN server abroad, and then all services and sites on the Internet will read this as the user’s presence in the particular country from which we buy the service. This is how, for example, journalists abroad work when they want to get some information, which is usually not accessible. The server decrypts the data sent by the user through the tunnel and then sends it to the global network. When the data comes in from the Internet, the server encrypts it and sends it to the user.

A VPN protects from:

• Data theft
• Eavesdropping
• Third-party traffic analysis.

The VPN connection can be set up on a computer, Android phone, iPhone, tablet or router.

What else do we need a VPN for?

In December 2017, the U.S. Federal Communications Commission repealed the net neutrality requirement that users have free access to networks without discrimination against any group. Internet users’ activities can be tracked by various entities, such as government agencies, marketers and others.

Many users go online at public hotspots. Such places are a paradise for cybercriminals. VPN is therefore part of the solutions related to comprehensive network security, available to every business and Internet user.
