What it is and how to use a VPN

A VPN (Virtual Private Network) is a private network that extends through a public network , such as the Internet, allowing connected devices to send and receive data as if they were connected to a local network. And the least in computer security . You should consider using VPN – ininja if you want to connect to a remote network through the internet or connect multiple networks securely. Also if you are concerned about privacy on the Internet and even more, if you want to avoid regional access restrictions.

What is a VPN used for?

Extend connectivity geographically:  using a VPN you can connect to the internet as if you were in a specific country. For example, if you need to watch a movie that is only available in the United States; You can connect to a local network in this country and consume the content without problem.

Ensure security in public connections: If you are connected to a public network at an airport, for example, and you must authenticate to sites with an unsecured connection. That is, sites with the HTTP protocol, in which navigation data passes without encryption through the network. A VPN, in this case, will allow you to secure your connection and ensure that our data is not intercepted by sniffers.

Evade blockages on the Internet: In some specific countries or regions, or even in some companies, there are certain internet access controls. That is, you cannot visit certain pages. With a VPN you can avoid this type of restrictions.

Evade restrictions on your ISP: Many internet service providers control the traffic of certain services on the web. This is the case of YouTube, for example. They can do so by identifying your activities, since they have access to all your history. They know the sites you visit and even the files you download. The only way to prevent your internet provider from being able to obtain this information is to encrypt your data . In this way, they can read them in a clear way, but they cannot be intercepted. With a VPN, all your data transferred between a device and the internet will be encrypted and the ISP will not be able to determine exactly how to restrict all those services.

How are VPNs classified?

They can be classified into two broad categories:

1. Remote Access: It is the most used model currently. Users connect from remote sites through the internet to local networks. In the business field it is widely used; because employees use it to access internal resources of the company from anywhere in the world, which can only be accessed locally.

2. Point to point: Point to point connections connect complete networks to others. For example, a complete office at the headquarters of an organization.
