VPN (Virtual Private Network) - is a protected network or tunnel over another insecure network, such as the Internet. All data sent over the network are encrypted.
Encryption - this is transformation of information to make it unreadable for third parties. At the same time trustees can spend decryption and read background information.
Advantages of using VPN
Below are listed main advantages of using VPN connections:
1. If you are using a VPN connection all data is encrypted and can be decrypt by the recipient and the sender only. Users can be sure about the security of data transmitted through a non-trusted network.
2. Service Provider does not see what resources the user visits and therefore cannot collect statistics on them, to block, to implement their scripts, toolbars, etc. This is especially important when using public Wi-Fi points in airports and subways; cafes and restaurants; hotels and shopping malls, and other potentially dangerous networks.
3. VPN allows you to get access to blocked and/or geographically non-accessible services. For example, Spotify service is not available in Russia, and to bypass the geo-restriction is necessary to connect to the server from the list located on the territory of Germany.
4. Attending customer resources do not see his real IP address, they see the VPN server addresses, to which the user is connected, and cannot determine the true IP location.
Distinction of Proxy on VPN
Proxy-server - a kind of intermediary between the Internet and your device. When using Proxy-server traffic will pass through it and the resources will be visited to see his IP-address instead of the real. Proxy-server is ideal for bypass geo-restrictions, but not suitable to ensure anonymity and protect the transmitted data.
Unlike VPN, Proxy-Servers do not encrypt the data passing through them, all data is transmitted as it is and can be intercepted by anyone, if not using SSL.
