facility that generates protection for the communication channels of an organization. It ensures proper security at affordable prices and also helps in increasing the overall performance of the organization. VPN can also help in providing access to the remote users.

The channel that allows the VPN to work on almost any existing data service standard is known as the VPN Tunnel.
Many data transmission technologies support the VPN and this makes its operation smooth and flexible. The VPN server is compatible with most of the data transmission techniques which includes regular phone lines, cable lines, DSL, T1 lines as well as Wi-Fi. A strong VPN service hides the complexities related to the technology and the data backbone from the user. There are many factors that are used when selecting data transmission technologies for the VPN service. These factors are performance requirements of the organization, reliability of the technology being used and the price of the service.
The two main advantages that the Virtual Private Networks or VPN can provide are cost savings and scalability. Let us discuss how these advantages of VPN will prove helpful for your organization.

The Low Cost of a VPN
There are many ways to lower the costs that are incurred by the organization when using the VPN service. The long-distance leased lines are very expensive so VPN uses these leased lines for a short dedicated connection between the organization and the service provider. The VPN service provider could also use a local broadband connection like DSL service rather than using the local leased lines.
The long distance charges for remote access are quite high. VPN helps in reducing these costs by providing VPN clients with the facility to call the nearest service provider’s access point. This will not only give you the ability to use remote access service but will also let you to do long distance call at affordable prices.
VPN service is also beneficial to get rid of the support burden and giving users the benefit of lower costs. When you use VPN, its service provider is responsible for supporting the dial-up access rather than the organization. If you are directly using

the dial-up connection for your organization then it will surely cost you a lot but if you instead use it from the VPN service provider then it will be cost-effective for you.

Scalability and VPNs

The traditional leased lines are actually very low priced but as your organization will grow so will the price for the leased lines. In fact, the cost of leased lines will increase exponentially making it difficult for you. For instance, you will find that a company having two branch offices will need only one dedicated line for connecting two locations. Think that you have expanded your company to have one more branch office then you will need two more leased lines in order to connect to the earlier two branches. Similarly, four branch offices will need six leased lines for full connectivity while five offices need ten offices and so on. This dramatic increase in the need for leased lines causes a combinatorial explosion that can limit the flexibility for the growth of your organization. This issue is solved easily by using VPN which makes use of the Internet for providing the geographically distributed access to the users.

Our blog tells about the various benefits that can be achieved by using the VPN services for your organization. If you are looking forward to get more information about VPN then stay tuned in to our blog.
