How a VPN Works and Why Use One




VPN is the acronym for Virtual Private Network, or virtual private network, in our language. A name that makes it quite clear that we are dealing with a network technology that allows secure connections to be established from a local area network over a public network such as the internet. In essence, a connection between two networks that allows you to browse privately.



And the key, beyond the network and your privacy, is in the virtual. Because a VPN also serves to establish a secure, private and virtual point-to-point connection through dedicated connections. It is like a reserved means of communication and apart from those used by the rest so that the information that travels through it is not visible.

How a VPN works

Let's imagine our computer as a person. When our team accesses a website, a service that works through the internet or downloads data, it is visible on the network of networks. It is as if a person goes out to buy bread, to the supermarket or to withdraw money from a cashier. It looks, anyone can do it, and that implies that it can be traceable. They can follow the person and also our team.



When a VPN comes into play, in the example of the person a superpower probably not infallible, but very reliable would come into play: a mixture of invisibility and anonymity. Or, putting aside the fantastic, what we get are secret, underground passageways through which to go anywhere. Something like this is what these networks provide us.




Instead of appearing on the network as a specific computer that connects to it through a specific modem, we do so through the computers provided by the VPN

The encryption that virtual private networks have allows us not to leave a trace on our behalf. Instead of appearing on the network as a specific computer that connects to it through a specific modem, we do so through the computers provided by the VPN.



We are not the ones We speak with our internet provider as an intermediary for our access to a certain service, we keep going through it but only to get to the virtual private network server. For practical purposes, our browsing is done by the VPN, from the many connection points that it may have around the world and that vary periodically, and that is what causes our anonymity.

The quick answer, after the explanation about its operation, is clear: Privacy.



A virtual private network provides us with anonymity when browsing the internet or using connected services, allowing us not to be traceable. And this should not sound like a solution for certain types of person, but it can serve anyone because beyond privacy, these benefits also redound to safety and versatility normally unattainable.




The use of a virtual private network not only provides us with greater privacy, but also more security and versatility




Our security improves because the data can no longer be easily linked and our browsing and activity on the internet, from the simple reading of a medium to carrying out banking transactions, becomes invisible to potential attackers or snoopers. Especially when we talk about the use of private Wi-Fi networks used by other unknown people and, above all, when we use public Wi-Fi networks.



In addition, the use of a virtual private network allows us to bypass the limitations of content by location by being able to locate ourselves in other countries, hide our habits from our IPS or anyone who I listened the network, bypass certain firewalls, or bypass censorship in certain countries.
