How does a VPN keep me secure?
Let’s say you want to write a letter to another person in another country. But to get there, you have to go through other countries and you don’t want anyone else to read it.
In addition, people in the destination country want to make sure that the letters they receive are really from who they say they are.

Then you encrypt the letter. But someone could intercept your letter and see who it is addressed to, and then try to impersonate you and send your own letter to the same person. But if you encrypt that person’s address, no one who handles the letter can deliver it because they cannot read the address.
Therefore, the country of destination establishes a special service for all its residents: one person is assigned in the country to be a “proxy” for everyone in the country. So, when I send my letter, I encrypt everything, including the address.
I fill in that message in another envelope addressed to the proxy. The letter goes through all other countries and anyone can look at it, but the only thing they can read is the address of the attorney, not the address of the person to whom it is really intended. Eventually, the proxy obtains the envelope, opens it and deciphers the letter inside and then reads the address of the destination and delivers it.

The proxy is very trustworthy: the recipient trusts that the proxy will not retain, alter or redirect any letter badly, and the proxy guarantees everything it delivers. In addition, the proxy vpn is well trained in security: it never uses a password as a ‘password’ nor any of the stupid things that ordinary people make compromise security.
It’s called a virtual private network because, even though the envelope passes through many hands, its content is completely hidden from anyone between you and the proxy, so it’s as if you had your own private route to the proxy.
Of course, someone in the middle can drop the message completely and not pass it to the proxy, but the messages can be lost even if you really had a private messenger to take the envelope to the proxy, so you would have to deal with the lost messages. anyway, through thanks, etc.
Personal VPN Service
There are three ways in which VPNs are used. The goal of all three is to connect two points securely.
1. Site to site: it has two offices and you want to be able to access shared files, internal websites, etc. from both locations. A VPN allows you to do that safely, which is also known as creating a WAN (Wide Area Network)
2. Remote worker to the office: has an employee (or several employees) who need to access the previous resources remotely. You can install a client on the remote worker device (smartphone, tablet, computer) that provides secure and encrypted access to the office network.
3. Personal VPN: A personal VPN is used to encrypt traffic between you and the Internet. Users choose this so that their traffic cannot be tracked or through firewalls that block access to certain sites (as in some countries such as China, Iran, etc.). Essentially, a direct connection is established between your device and a server somewhere outside the country. From there, you are free to search the web!

VPNs come in all flavors and sizes using a wide range of technologies (protocols) and typologies. There are hardware VPNs that require manual configuration and network knowledge. Then there are the software VPNs that may or may not require configuration. There are a lot of personal VPN providers that usually charge $ 5- $ 10 / month for that service.
