Virtual Private Network: What is it and why does the protection of your privacy so important?

Virtual Private Network

Computers and the Internet have become one of the main means of transmitting and processing information. Most of the information on the internet is open to all users, so many companies are providing the internet to their employees, protecting corporate traffic.

VPN is capable of providing reliable and coordinated work between the company’s computers. It is also capable of transferring corporate IP traffic using a secure protocol.

Modern VPN makes connections into local computer networks using virtual dedicated channels and the shared public Internet. More information on choosing the right service to operate your business from a distance can be found here.

The protection of privacy is guaranteed by the use of the encryption protocol or IPSec. In addition to the most common IPSec, PPTP encryption technology is also used to develop PPTP VPN encryption technology.

Their high reliability is supplied through a firewall at the exit of one of the local and other local networks. The server of access directs the VPN work. It provides a secure client, routing and remote access connection.


Modern VPN can be created based

  • Firewalls, which provide transmission and encryption of data;
  • Creation of secure channels using routers;
  • Software solutions;
  • OS;
  • Special hardware devices.

The type of used environment is split into secure VPNs including the trust network IPSec, OpenVPN and PPTP. The nomination will be divided into

  • Intranet VPN, which combines several of the company’s local networks
  • Remote access a single user’s VPN connection to the corporate network
  • Extranet VPN supports customers from external users.

The speed of the information crossing is a very important feature in addition to the strong encryption. VPN technology provides high data protection from unauthorized access when all network components are properly configured and each user has unique login and password.

Practical application:

VPN allows you to create a virtual network like a local one, but there is no physical connection between the computers.

The convenience is that between the computers of users from different countries and continents you can create the analog of a local network. The only negative is that without an Internet connection such a network won’t work.

But today, most online operators offer the World Wide Web constant, high-quality access. This is high-quality in local network development and careful corporate network organization.

This direction is very popular at this stage, with more and more companies paying attention with all their facilities to their own VPN. Cash investment will, of course, be an important component of such technology’s success and quality.
