VPNs Until a while ago, they were only known in business environments, but they have become popular, in part due to their advertisements on YouTube, websites and other platforms that They promise greater security for the personal data of users and the possibility of accessing content that is not available in their countries of residence.
To begin with, a VPN is a virtual private network, for its acronym in English Virtual Private Network, which gives clues that This internet service can be used to browse the web anonymously, similar to the incognito browsing function of web search engines such as Google.
According to the above,a VPN works as a tool that hides the user’s browsing datathat is to say that the computer for internet terms is identified with an IP that is the identification number of the device, what the VPN does is hide or prevent internet service providers and third parties from knowing the identity of the computer and its origin , which prevents access to data such as search history or personal data .
In this way, ISPs or internet service providers will not be able to access the data of the computer and the user, as well as the searches carried out on the internet and the sites visited.
In practice, this means that marketing companies cannot know the habits or behavior of people, preventing the user from coming across invasive ads.
All this, because during web browsing, there is an interaction between the internet and the computer, and its communication channel, so to speak, is the service provider that connects the device with the web.
Finally, what the VPN is going to do is that before the Internet it is not possible to identify where the searches come from and the user who performs them.
But then, are VPNs really safe or not?
According to a Kaspersky article, these types of tools, although they protect the IP identity of the computer making it impossible to access data and search history, It doesn’t work like an antivirus program because even if you enter a malicious website, your device will be contaminated and attacked.
In other words, even if a VPN is used, the danger continues with Trojans, bots, malware, spyware and, in general, any type of virus that can damage the computer or steal sensitive information.
Likewise, there are a large number of free VPNs on the internet that, in this case, instead of being helpful in protecting identity and personal data, on the contrary, could put them at risk, that is, the use of these VPN functions free way is not recommended because personal information and the device could be compromised.
Some risks of using free VPNs
A report from the University of California in the United States titled “An Analysis of the Privacy and Security Risks of VPNs for Android” indicates that 38% of the VPNs that were investigated contain malware, also known as computer viruses. For this reason, it is important to know the risks to which you are exposed when browsing with a free VPN.
1.Computer threats hidden in advertising
If the VPN brand is free, it will somehow be financed and one of them is the advertisements that are usually invasive and in large quantities. If the user accidentally clicks on any pop-up window, a virus could be entering the computer.
2. They track internet activity
While internet providers and third parties won’t have access to browsing histories and data, VPNs will, and in order to stay in business, they might sell them to companies that then flood users with commercials and advertising offers.
3. They do not unlock content from other countries
Most VPNs promise that you can access streaming content that is available only in certain countries around the world, but if it is free to use, it is very likely that you will not be able to view it. Now, if access is given, the loading speed will be too low.
