Benefits of a VPN

Business Long Distance - Guaranteed Lowest Rate Program

Probably the greatest benefit of a VPN is the ability to save a company significant money on their networking needs without sacrificing reliability, speed, functionality or security. Before the emergence of internet based technologies, businesses wanted to share data in a private and secure manner were required to create networks based on physically linked connections.

However, businesses needing to share a large amount of information across the country or even the globe were faced with often exorbitant costs related to WANs and modem banks.

Now a company can get the cost saving benefit of a VPN by utilizing cost-effective third-party internet transport to connect remote offices, remote users and even telecommuters to the main corporate site. By incorporating high-bandwidth technologies such as DSL, companies can reduce cost while increasing remote connection bandwidth. This will result in the additional cost savings of increased productivity for the work team as a whole.

One last cost benefit of a VPN is the ability for the network to be expanded in scale without the requirement of adding significant infrastructure. Since internet infrastructure can be provision easily with ISPs and devices that easily allow for the addition of new users, the company will not face the problem they once did with lease-line based networks of the cost of adding additional physical band-width.

Increased security is another benefit of a VPN. Depending on how they are provisioned, a VPN can provide the highest level of security possible by using advanced encryption and authentication protocols that protect transmitted date from unauthorized access. While there are other technologies such as SSL that provide encryption options for data, SSL is limited in the number of applications and protocols that are compatible with it. VPN doesn't have this restriction, allowing for more flexibility to meet the company's needs.
