What is VPN and How does it work

Did you know that several online services are based on the data you deposit on the Internet?

Do you remember doing a search for a certain product on a shopping site and, in the following days, having your inbox flooded with "offers" of the same product? Have you seen the price of an item in an online store and, when you went back to buy it, realized that the price had changed?

If you answered yes to any of these questions, you may have noticed that the Internet works like a radar that captures, stores and passes on all the activity you do on it. If you are not happy with this situation and want to browse with more privacy and security, then you need a VPN. 

What is VPN?

VPN is an acronym for “Virtual Private Network” is a service that allows users to access the web safely and confidentially, route connections through the server and hide your activities in cyberspace. It is called a private network because the connection is encrypted, you are the only one to browse it. The VPN serves as a mask for your IP address, making it “point” to a different location than you are.

Why You Need to Use VPN?

Prevent Internet Provider from Accessing Data

Google, Facebook and other companies watch over you. It is the price to pay for having their services for free: they use your browsing data to attract advertisers, who are the ones who grease the operation of all this machinery with their money.

However, as much as they try, there is only one company capable of knowing which websites you visit and when: your Internet provider. The telephone company that providing you Internet can know exactly your browsing history, although this data is handled privately so that no employee or hacker can access it.

Defeat censorship

One of the advantages of VPNs is that you can browse as if you were in another country. This can be used for legal practices, such as watching streaming services that are not available on yours, but also to make it easier for many activists.

In certain countries, freedom of expression and opinion does not exist, and crimes committed on the Internet are severely punished. It is what drives opponents to take refuge in virtual private networks as a way to prevent the government from spying on and detaining them.

In China, for example, they are prohibited, although many use them to access Twitter or Facebook.

Securely connect to public WiFi networks

Public WiFi networks are not secure. A cracker with sufficient knowledge can access private and personal information from all devices connected to the same network as him. So it is advisable to avoid these networks whenever possible.

If you can’t, at least take some precaution, such as connecting anonymously with a VPN. It is not a foolproof measure, but it will make it more difficult to access all the information that flows to or from your device.

Avoid being hacked

We have said before that being hacked is relatively easy on a public WiFi network. Even in private, it is also if the criminal in question has data such as IP or has managed to sneak malware into your PC.

A good security measure is to hide your address behind a VPN, which will provide the attacker with a bogus address.

Access Netflix and Sports Streaming from Other Countries

The content made available by streaming services like Netflix may vary from country to country. The VPN can unblock this content based on the country you choose to connect from.

Also you can watch youtube content that is not available in your country.

Remote access to your office for teleworking

Many companies use internal networks to handle documents or information. The problem is that connected equipment needs to be physically connected, a problem if you want to work from home. This prevents one of the most unknown advantages of VPNs : you can access the work network remotely.

Now that teleworking is beginning to gain strength as a method of reconciling work and family life, many companies should explore this possibility.


Regardless of whether you download legal content, downloading via torrent can be blocked by some internet services or make the download speed extremely slow. Through the VPN, the user remains safe when using peer to peer file transfer networks and ending the blocking of downloads. This also makes the transfer speed faster.

How does VPN work?

When we connect to the Internet, the device we use for them connects to our Internet provider or ISP, which is in charge of requesting the information requested from the Internet. This information passes through our provider’s servers, so that our ISP can access all our activity on the network.

When we use a VPN, what we do is hide this information from our provider, since we connect through a server with an encrypted connection. In this way, the data or information requested and returned cannot be seen by our ISP.

That said, we must know that VPN clients are software that providers provide us when we start using their service. This client allows us to easily run the VPN services on our devices, so we only need to run the client, choose the server to which we want to connect and we will automatically be connected to the Internet through the VPN that we are using. As soon as the client establishes the connection with the chosen server, all the information that travels between our device and the Internet is encrypted and is therefore inaccessible by third parties.


We can find lot of free VPNs, however, we must be very careful with these, since the great popularity of thie type of VPN has made them the target of those seeking to distribute all kinds of malware. That is why, there are many ads that offer VPN completely free of charge, those who have some type of hidden malware that will try to infect as many victims as possible.

This is undoubtedly one of the great disadvantages of free VPNs versus paid VPNs, however, this is not the only one. With a paid VPN we can also forget about the uncomfortable ads.

 But without a doubt the most important thing is that paid VPN they offer us connections without speed loss and more stability, it does not track our activity on the Internet and they usually offer a technical service to solve any problem that we have with its operation or configuration.

On the other side, free VPN usually have speed limitations or keep record the activity of the users, something that the paid ones do not do.

Also free VPN use shared IP addresses which can be easily detected by certain websites or services like Netflix and hence these block access on these shared IPs.

What are the best VPN Providers?

There are numerous VPN services on the market, some paid and some free. Obviously, free ones usually offer very basic functionality, without guaranteeing a fast and stable connection, in addition to having traffic limits. Therefore, in some cases, only a paid service can fully meet your needs.
