What is VPN

By:    Updated: February 8,2017

Virtual Private Networks (VPN) encrypt and protect your data connection over the Internet. A VPN secures data between you and your business, or you can obtain anonymity and protection for your personal information using a VPN provider service.

What is VPN ?

VPN connections are sometimes referred to as "tunneling". Usually, you have some type of software installed on your computer, and you use that software to connect to the VPN service. This service can be within a corporate network, or you can connect to a private server that you use for Internet access. You must authenticate before accessing a VPN service, which means you need a username and password to access the network. This protects your connection, so only you can access the service.

 

After authentication occurs, you then have a secure connection between your computer and the server's network. The server's administrator can limit access to services from the server-side, but for the most part, you have similar access as if you are authenticated locally. All data is encrypted between your computer and the server, which is especially important when you access private networks over the Internet.

VPN Benefits and Usage Scenarios

Businesses can benefit from setting up VPN connections. VPN allows employees who are working from home to connect to the company intranet over the Internet. A VPN service gives protection to the business and the employees. The software is typically installed on the employee's computer, and the employee uses the service to perform daily tasks as if the employee is logged in locally.

 

Internet users can also benefit from VPN service. If you want to improve anonymity on the Internet, VPN providers give you a way to access the Internet through a "tunnel" service. You connect to the VPN service, and then you connect to the Internet from the VPN service. This type of access masks your communication over the Internet because the data is encrypted. It also displays the VPN's IP address when you connect to a website. This means that your private home IP address isn't exposed when browsing different websites.

 

Internet marketing people sometimes need a foreign IP to check website search engine rank or use tools that are only available to certain countries. VPN services offer you a different IP address, so you can "spoof" the IP address in the country of your choice. For instance, if you want to connect to a website or service that only allows United States users, you can use a VPN service in the United States to access the service. When checking website search engine rank for a particular country, you can use the risk free VPN to check statistical data from the target country.

 

VPN service has several benefits, but the overall advantage is the privacy through data encryption between your computer and the target server. Using your risk free VPN service, you can improve the protection of your data, and stay anonymous on the Internet.
