VPN architecture

A VPN connection is created using at least two devices. Server. The device on which the main software is located, listening on certain ports while waiting for a connection to the client. For example, a VPN service or a work network. Customer. The user's device from which the connection to the remote server is made. Encrypted information is constantly moving between the server and the client through the VPN tunnel, and all cryptographic data processing (encryption / decryption) is performed on the devices themselves. Therefore, in a tunneling environment, no one can intercept user data. A VPN connection is created using at least two devices. Server.

When connected to Wi-fi in cafes, subways, etc., so that hackers cannot steal your data. When using a public network, it is safe, except to browse sites in a browser. But if you use social networks, an attacker can not only intercept your confidential information, but also use it for his own purposes by logging into this very social network on your behalf. It's even worse if he manages to crack the mail. Then all applications associated with this mailbox will be attacked. But the most unpleasant thing can be a leak of your bank card data if you decide to transfer money to someone by connecting to free Wi-fi.

However, remember that not all information is encrypted. Different VPN providers may have different characteristics such as the degree of encryption, hiding the fact of connecting to the server, storing logs (a log that stores information about the sites visited, real IP addresses, etc.) and cooperation in providing information to third parties.

In general, regularly using payment systems, you should always keep the VPN turned on. Here the question of why you need a VPN is not appropriate. Using an anonymizer, you can always be sure of the protection of your data. That the provider, that the "curious" user will not be able to get data about your actions when you use the VPN service.
Protecting data when using Wi-fi in public places. There is always the possibility of hacking Wi-fi (not to mention passwordless networks). Having hacked into the network, hackers can easily get the information they need.

VPN encrypts the connection so even if the network you are using is not secured enough, your data traffic remains safe. The function blocks malicious sites and ads. Therefore, even if you accidentally click on the wrong link, the application will prevent access to the dangerous site.

VPN is optimal in terms of a set of characteristics (speed, degree of protection and reliability). It is used as the main one by most VPN services. Its plus is open source. This allows third-party developers to study it and look for vulnerabilities. If it is found, the owner company is quickly notified of the need to eliminate it.
