Network Security

Accessing blocked sites is possible via VPN (Virtual Private Network) — a network technology that provides constant encryption of all internet traffic regardless of the applications in use. This technology can be used not only to access remote sites or workstation but also for work with any internet resources while at the same time providing total security of the transferred data.

What we need is a free VPN client or tools; setup on a user’s computer that creates a secure connection with the server on the internet which is owned by a VPN service provider. Using the server, users can visit blocked sites, talk in messenger, pay bills, shopping, etc. The created connection is called a «tunnel» because it is impossible to get into it from the outside, and taking into account that all transferred data is encrypted. The tunnel protects you so well that not a single log about visited resources and actions you did will be left on your provider’s server.

These anonymous browsing tools keep you anonymous for your entire session and protect your passwords, credit card numbers from hackers or network snoopers.
