Why do I need a VPN?

You may be hearing a lot about VPNs and not have a clue what they are or what they do. A lot of people recommend using them. If you are interested in getting one, you should find out a bit more before downloading one. There is more to it than meets the eye.

Firstly, what is VPN (vpn o que é)? VPN stands for Virtual Private Network. This abbreviation helps us better understand what it is. A network is usually public, like the internet, or private, like a company’s servers. A VPN is, therefore, a virtually created private network, that doesn’t exist in a physical location, but that functions as if it does. This private network then allows you to interact with the internet in ways that are more private and secure.

When connecting to the internet, you are connecting to a public network, something which anyone with an internet connection can access. This exposes you to other parties using the network. For the most part, this does no harm, but there are people that abuse this ability to find out private information from other users. This is where VPNs come in. They allow us to communicate with these public networks via the virtual private network, which protects our true identity and the information we are sending.

Now that you know the basics of what is a VPN network (o que é rede vpn), you can look at different uses. The initial purpose was the security of sensitive information, and this is still one of its main uses. But now VPNs are used for other things as well, one of which is for accessing blocked content online.

Sometimes websites block users from other countries or your ISP may limit access to certain websites; either way, you can use a VPN to hide your original identity and change it to a virtual identity of your choosing. You can choose from a variety of servers, so whether you want to watch Brazilian or USA Netflix, you can choose the country and begin watching. Torrent sites might also be blocked by your ISP and by using a VPN you can get around this.

Another popular use is to reduce prices. There are various online shops and services that change prices based on your shopping location. This will not always work, but it is worth trying out, especially when it comes to accommodation and travel. Skype is another example. By changing your location with a VPN to the country you wish to call, you are able to make international calls at domestic rates.

Whatever your reason for downloading a VPN, their uses can’t be ignored. When searching for a VPN online, make sure to do adequate research about the pros and cons of various ones. Some provide better quality service for different uses. It is also worthwhile investing in a premium VPN, as the free ones can often lack necessary customer support. Most of them have trial periods or money-back guarantees, so try one out first.
