Any VPN you find online

If you had ever heard or read something about VPNs or Virtual Private Networks , it will surely have been to praise its great advantages when it comes to surfing the Internet , especially if we do it from an open or public Wi-Fi network to read more .

It is true that a VPN encrypts our communications and improves security, but it is also true that neither the entire mountain is oregano nor is everything that glitters gold, so if you are thinking of using a VPN solution from a secure provider, be very careful, Because some of these services suffer failures and leaks that could put your privacy and security at risk.

Although there are many VPN solutions on Android , as a general rule and understanding what a VPN is, you should never use a stranger's private network unless it is fully trusted , just as we do not use Wi-Fi networks that seem unreliable . But let's get into the matter a bit ...

VPN? What the hell is a VPN?

If we are clear about the concept of a local network , which is the network that any of us can have at home with the router and several connected devices, it will be very easy to understand what this is from a Virtual Private Network or VPN.

Broadly speaking, and without technical explanations, a VPN allows a device to connect to a local network through the Internet by sending its data traffic in encrypted form. That is, if you created a VPN in your home, you could connect from anywhere, over the Internet, as if you were doing it from your living room.

The implications are several, and all lie around the encryption of communications and connection through the local network , which these cases make the real Internet output of the device connected through a VPN, is precisely the local network of destination. In addition, the device in question would be virtual connected to the destination network , or what is the same, you would go to the Internet from your home network just as you would if you were connected from your own home.

Does it have advantages to navigate after a VPN?

Well, it really does have advantages, some of them also key, such as that we can connect to an open Wi-Fi network from anywhere without fear that anyone can capture our communications and inspect them, they will be encrypted.

A VPN also allows our Android device to go online virtually from another site , so we can skip the regional protections of some services, such as those that restrict access to a series, news or sporting events depending on the country of the connection.

Likewise, it is also possible to connect from anywhere to our local network as if we were at home , using connected computers or printers without any restrictions, and even being able to make VoIP calls as if we started them at home.

Why shouldn't you trust a stranger's VPN?

For many, the reason may already be obvious after the explanations, and if we use a VPN to feel more secure and nobody can read our data traffic, you should know that this traffic will reach the VPN provider that can effectively read it and analyze it even more than it recognizes openly.

Purposes for this analysis can be endless, and no matter how secure the VPN provider is shown, it is a private network of a third party that manages that someone , so this network may have unintended security problems and leaks that They could jeopardize the privacy of users connected through it.

In fact, the gap detected in WebRTC that allowed to obtain the real IP of the users connected after the service, questioned all those so-called “secure providers”, who are still trying to recover from the coup.

According to the well-known security expert VoidSec, up to 23 percent of the best known VPN providers on the Internet leaked IP addresses of their users through WebRTC, a problem that has been dragging on since 2015 and for which there are some plug-ins or accessories that repair it.
