The advantages and disadvantages of using a vpn tool
As I mentioned in the introduction, the acronym mean Virtual Private Network VPN or Virtual private network, a network technology that allows you to configure a secure extension of local area network (LAN) on a public network or uncontrolled, such as the Internet, allowing you to communicate from one point to another (such as a smartphone and a computer, or between two smartphones) securely and privately using the Internet.
The technology behind this type of connection is called “tunneling”, as it creates a “tunnel” establishing communication between two points, by which circulating data. The VPN itself does not store any kind of data, they are saved on servers or clients that configure the VPN.
One of the main uses of VPN technology is to wrap a private IP to a corporate network or company within a public IP, so that employees who work from home can connect to the Office network by accessing the services, resources, servers, etc. Another common use is to open WiFi networks from the smartphone, but in most cases, the data traffic might not be safe.
What is a VPN?
One of the main uses of VPN if you can access websites and services restricted in certain region. Applications unavailable in Brazil, for example, can be accessed through a VPN network.
In addition, a private network is inherently more secure when the subject are transfers of sensitive data by email, for example.
Advantages of a VPN
Use a different IP to the place where we are
One of the advantages of a VPN connection is to use a different IP address than the one that we are connected. For example, to download an application that is only available in a particular country or to access a specific channel of a country other than that in which we find ourselves.
Connect to open networks with security. In open networks or free, is there any risk that someone connected to the same Wi-Fi network can monitor traffic and steal your passwords. If we use a server connected to a VPN, all data going through this open network will be encrypted until you reach the VPN server.
Access a local network via internet safely. This is an application of VPN to business. Using a VPN connection you can connect to a local area network via the Internet securely.
So that the VPN connection is completely safe, we must rely on the VPN server. There are many free VPN services that control data traffic they receive from users. In addition to collect their passwords (which is illegal), these services also check usage statistics and profiles of navigation that can be sold to third parties, such as advertising agencies and other companies dedicated to consumption.
A greater use of data slows the browsing speed. When connected to a VPN, all data is encrypted to increase the amount of data that is transmitted. On a slow network, this results in slower navigation and if you are connected to your data plan, spend faster our monthly package.
