What is a VPN?

A VPN, or Virtual Private Network, refers to a network that simplifies the connection between multiple computers. It is used to create a trusted private connection, where the identity of the connected parties is continuously verified from both sides.

How does a private network function?

Computers connected in this network communicate with each other in the same manner as they would in a trusted private network, continuously verifying each other's identity using digital certificates. After this verification (without which a VPN connection is not possible), data transfer and all communication are encrypted.

The result is the creation of a secure encrypted connection on unsecured networks, primarily the internet. This connection is made through a passage known as a VPN tunnel, to which only authorized and approved users can connect (using a password, digital certificate, or username).

How can a typical user utilize a VPN?

With a VPN, you can remotely access systems like a company's information system and also protect your private web communication and identity. It enables you to watch movies (like those on popular platforms like Netflix) that are blocked in your country, browse websites accessible only to citizens of specific countries, and more. This is why VPNs are increasingly used in households.

VPNs are also of interest to businesses

Since the system of reliable encryption and the use of tunnels allows hiding IP addresses, circumventing censorship, and avoiding geoblocking, it is used for conducting business transactions and can give the impression of communicating from the location of the provider's server, like from a different city or even a different country.

Advantages of the VPN network

As a user or network administrator, you will appreciate the ability to seamlessly expand or enlarge an existing VPN network as needed. You also have the option to set your own priorities and choices regarding the appearance of the virtual environment. Additionally, VPNs can easily mitigate risks associated with connecting to public Wi-Fi networks. Lastly, you might find it useful to bypass regional restrictions on websites designated for certain countries.

In summary, a VPN is a system for connecting computers into a secure private network, even when they are in completely different locations on the internet.
