What is a VPN?
VPN (Virtual Private Network) is a common name for a technology that allow you to create a connection between two or more computers or servers (logical network) through another network.
Thanks to the use of encryption and cryptography, the security level in the core network does not matter. This allows you to use public internet for the connection, because you always have a third party between the user and the internet, for example - an Internet provider. Therefore, in the VPN technology itself, there are various mechanisms and tools for protecting the transmitted data from interception, repetition or modification.
Most often VPN is used either for corporate use, when connecting to some local resources that are not available from the Internet, or for personal, private and secure surfing on the internet. VPN servers can be located in any corner of the globe, and at the same time be just a click of a button away.
