What is a VPN connection and Its Benefits

By | July 14, 2020

Connecting to a public WiFi network is dangerous because you don’t know who else is connected to that same network or what their intentions are. But if you need to do it, a good security measure is to do it through a VPN connection.

In this post, I am going to explain everything you need to know about VPN and how you can configure it to start using it on your Android or iOS mobile and on your computer.

What is a VPN:

VPN (Virtual Private Network) is a network technology that allows one or more computers to be connected to a virtual private network, through a public network such as the Internet, without the need for the computers to be physically connected to each other or to be in the same place.
In this way, two or more devices can communicate and exchange data securely and privately through a username and password.
It is widely used by companies to allow their employees to connect from anywhere to the corporate network, where they can access corporate resources that they could not without it. Although this is just one of the things you can do with a VPN.

Types of VPN networks:

Mainly, there are two types of VPN networks, depending on which they are based:

Client-based VPN: Allows a user to connect to a remote network through an application, a user and a password, creating an encrypted channel between the computer and the network, in order to carry out a secure data exchange.
Network-based VPN: Allows you to connect different networks to each other over the Internet. This type of VPN network is used by companies that have offices in different geographical locations, in order to connect them all and share information securely.

What is a VPN for?

Teleworking: Allowing access from anywhere to a company’s network is not safe, since, through an open WiFi network, the access password could be captured and could give access to anyone. If the worker connects through a VPN, the connection is encrypted and will have access to the same information as if they were in the company.
Fake your location: When you connect through a VPN network, your device communicates with the VPN server and it with the Internet, so your IP will have the location of your VPN server. With a VPN network, you will be able to access content that is available only in some country, or that is censored in the country you are in (many users in China use a VPN connection to connect to Facebook).

Add an extra layer of security: If you want to connect to a public WiFi network, this is a great solution, since it provides security so that anyone connected to that same network cannot access your private data, as long as you choose a good server for your VPN. It is a good security measure to avoid falling into some kind of scam on the Internet.
Bypass restrictions on your ISP: Many service providers control traffic to certain websites or services, such as YouTube, for example. In this way, they know the sites you visit. Through a VPN, this data will be encrypted and you will not be able to obtain that information.

What are the advantages of using a VPN

  • You can use it from anywhere and from any device connected to the Internet.
  • It is a secure and private way of sending data or browsing the Internet.
  • They are easy to use and, once configured, you can quickly connect and disconnect.
  • You can access your network from anywhere and safely.
  • Provide security to your connections through (PWNpublic WiFi networks.
  • Allows you to avoid censorship on the Internet (in some countries, some social networks are censored, but with a VPN you can access them).
  • You can enter sites from other geographical places (before Netflix Spain was created, many people used a VPN network to connect to Netflix USA and be able to watch series and movies through this platform).

What are the disadvantages of using a VPN

  • There are free VPN services, but some track their users to get usage and browsing statistics that they can sell to third parties. If you want to guarantee your security and privacy, it is better to use a paid VPN.
  • The connection slows down since all the data we send and receive is encrypted.
  • They cannot always falsify your location, especially if you use it on your mobile.
  • Your security is not foolproof, only an extra layer of security is added.
