How and why using a VPN improves security

Whenever we enter a web page, log in to a social network such as Facebook or use any service on the Internet, we are sending and receiving information. This data does not always travel safely, as we could have significant problems if it is intercepted and ends up in the wrong hands.

A VPN is a program that can help you avoid this. What it does is basically create a tunnel through which that information travels in a secure and encrypted way. Currently the strongest encryption is 256-bit, which is used by some of the most popular such as ExpressVPN or NordVPN .

If, for example, we are going to connect to a public Wi-Fi network , the data we send could be intercepted by a possible intruder on that network. It could even steal passwords when we log in or make a payment. But when using a VPN, all that data is going to travel encrypted in a kind of tunnel. This is how we improve security. However, you should verify that the VPN is working well and that it is not leaking data of any kind. Otherwise its use would be of no use.

Hide important data when browsing

The VPN will also hide important information that can be leaked when browsing the Internet. This data can be collected by the sites we visit themselves. For example, if we enter a page to check the weather that is going to do, they will know our location, IP address, as well as other data related to the system. What this program is going to do is hide all this and allow us to navigate with data that is not really ours. Our physical location would not be exposed, nor would the IP. If we want to browse with total anonymity , it is undoubtedly an option to consider.

In addition, a very important detail is that nowadays all VPN services have the Kill-switch functionality, a security option that allows you to completely block Internet traffic from your computer, in the event that the VPN connection is has fallen. This allows us to protect ourselves against possible unintentional data leaks. In the case that we are the ones who deactivate the VPN, then this Kill-switch will not work, it only works in the event that the VPN service has gone down.

Another way to help improve security is by allowing users to connect remotely without putting data at risk. For example, for teleworking, something increasingly present, is very interesting. We will be able to connect from home or from anywhere to the company’s computers without having to be physically there, but without jeopardizing security at any time.

Therefore, the use of a VPN is very useful in order to improve security. Of course, we must make sure that we use a program that works well, that is reliable and has a good performance in terms of speed and stability. Our advice is to avoid free VPNs, which can be a problem. We will also prevent the VPN from disconnecting if we use a reliable VPN program and service. If you need to use a free VPN, our advice is to make use of WARP from Cloudflare, it is currently one of the best VPN services and the fastest.
