What is a VPN And What Is The Best VPN Service?

The world is dependent on the Internet in order to move forward. Enter VPN - a cutting-edge innovation that takes personal or corporate networking and information management to new heights. Since its emergence, companies are slowly turning away from using leased private lines or dedicated channels to VPN. This post discusses what a VPN is, why it is beneficial, and what needs to be considered when searching for the best VPN service provider.

What is a VPN?
A Virtual Private Network or a VPN refers to a number of computers connected using a public infrastructure like the Internet. To illustrate, imagine this: you are in the US and you need to travel to France, Japan, and Australia to attend a conference. You need to travel by plane to do that. Imagine the US as your computer, France, Japan, and Australia as your organization's network places, the conference as the job you need to do, and taking the plane as the Internet. VPN comes in when you attempt to establish a connection between your computer and your organization's network by using a secured channel found within the Internet (the medium).

How Does VPN Work?
An employee falls into any of these categories: work from home, office work, and field work. In all of these types, employees will always need to access the company network so they can work. When a company utilizes a VPN, an employee will only do one thing: start a point-to-point connection with a remote server online. At the backend, the remote access server responds by identifying the employee. Once identified, the VPN provider opens the gateway to the company's private network. The employee can then start working.

Why Consider a VPN?
Traditional WANs were used by companies through leased lines. These lines allowed them to share information across servers without the risk of security breaches. But now that security features have become the hallmark of leading the competition, VPN providers offer opportunities for companies to save on costs because the channel of network communication can be done through a public network. The need to lease is eliminated altogether without risking security, functionality, reach, support, and productivity. 

What Makes a Good VPN Service?
Security. Common terms that relate to security are SSL, TSL, L2TP, PPTP, and IPSec. Know that all of these provide a secure connection for data sharing online. But what constitutes as the best VPN service under this factor involves data encryption. Companies that develop turn-key products that encrypt information sent over a VPN are better. Moreover, choosing a company that also provides anti-spyware or anti-malware features are the best.

Scalability.

A VPN potentially delimits the networking capability of an organization. The best VPN service providers are those that offer scalability features especially to companies that outsource or offshore their operations. As more people are added to the company, processes will expand, and functionalities will be required. Between these lines, information for transfer and sharing will accumulate thus demanding more "space" for effective management.

Manageability.

VPN servers are not limited to specific locations. VPN service providers also outsource and offshore their server locations as they try to widen their support on a global scale. When considering a VPN service provider, choose those that offer exit locations in places where you often do business. For example, if your company does offshore operations in the Philippines, the best VPN service would be one that has a server in that location.

Transparency.

While security protocols protect data when it's transferred, it pays to consider how little or how much a VPN service provider can get from such communication. This means that the best VPN service has a transparent logging policy. Some providers find it justifiable to log information sent across a VPN channel. And while that might not do a lot of damage in your company, your own security protocols should dictate the limits at which information can be accessed by third party service providers.
Price. The best VPN service can come free or paid on a subscription basis. Always remember that a free service comes with a drawback in terms of features while paid services can cause deliberation in terms of price. And where price becomes a benefit for free services, features become the strength of paid services. The balancing factor is still security or information and your business policies. Choose a service provider that offers the best features at a justifiable price.

A VPN is a marvel on its own; it does wonders to the capabilities of every business to function. Individuals can become key players, too. This makes VPN a flexible option for people who are highly-connected to the Internet. And while VPN offers convenience, there are factors needed for service provider selection. What more can be said when even individuals have the ability to set up their own VPN at home?
