A VPN is a transmission technology that lets you connect to a general network without restrictions. In this way, you will get the same rights and settings as in the LAN itself, even though it uses a publicly owned network. From a network point of view, one of the problems of internet networks (public IP) is that they don’t have good security support. Meanwhile, from a company perspective, IP is a basic requirement for exchanging data between branch offices or company partners. VPN appears to solve this problem. A corporate network that uses IP infrastructure to connect with its branch offices in a private addressing manner by securing data packets transmission. However, there are some differences between the best free vpn list and the free VPN available.
VPN technology provides three main functions for its users. With the use of public networks that are prone to data theft, VPN technology uses a working system by encrypting all data that passes through it. With this encryption technology, data confidentiality can be maintained. Although there are parties who can intercept data that passes through the internet and even the VPN line itself, it is not certain that they can read the data, because the data is randomized. By implementing this encryption system, no one can easily access and read the contents of the data network. When it passes through the internet network, data has traveled very far across various countries. During the trip, various disturbances can occur to its contents, whether it is lost, damaged, or manipulated by people who are not supposed to.
In a VPN, there is a technology that can maintain the integrity of data from the time the data is sent to the data arriving at the destination. VPN technology can authenticate the sources that send data it will receive. The VPN will scan all incoming information and recover information from the data origin. Thus, a VPN ensures that all data sent and received comes from the source it should be.
