VPN is relevant in the current conditions, especially when there is a question of protecting personal information, security and anonymity of users, as well as the freedom of the Internet due to endless blockages by Internet providers. Let's just try to explain: what is a VPN, for what purposes it is needed and how to use it.
What is a VPN in simple words
VPN or Virtual Private Network — a virtual private network built on top of the main network. The user node connects directly to the server, forming a kind of tunnel, and communicates with network resources through it. In other words, it is an isolated Internet “inside " the Internet. This allows the end user to hide their location, device data, and real IP address. All traffic is encrypted, so the data received does not provide any value.
Setting up a VPN is basically a difficult matter, and in China especially because the Chinese government is doing everything possible to prohibit the activities of such companies in the country and to completely control traffic. Nevertheless, you can still use VPN in China, and when choosing some providers, you don’t even have to configure anything at all.
After blocking some popular Web resources, many users started using special VPN services that allow them to bypass the established restrictions. They allow you to redirect traffic through an intermediate server, so the provider does not see which remote node the computer is accessing. However, not everyone knows that the main purpose of such services is to preserve the confidentiality of data. Their clients encrypt traffic on the user's device using modern cryptographic algorithms. Therefore, even if third parties can intercept the information, they will still not be able to decrypt it. 中國VPN services will be especially useful in unfamiliar wireless networks.
