Virtual Private Networks (VPNs)

Connecting Your Branch Offices and Remote Workers with VPNs

Connecting remote workers and branch offices at one time was a costly measure, requiring private lines and a substantial amount of on-premises equipment. Today, virtual private networks (VPNs) have changed all that. A VPN service uses encryption and other technologies to create a virtual “tunnel” through the public Internet, affording the same level of privacy that was inherent in the private line solutions, while eliminating the cost.

The VPN service technology provides an inexpensive and efficient way to broaden a company’s horizons and extend access to vital information, applications and data to all those who require it, regardless of location; also allowing even the smallest companies to create virtual partnerships with other companies and providers around the world.

Types of VPNs

If you have multiple offices telecommuting workers or traveling staff, chances are, you’ll need a VPN. There are several types of VPNs that suit different purposes. A more traditional VPN based on IPSec (Internet Protocol Security) is a stateful connection that is very well suited to permanent connections, for example, between branch offices. This type of VPN service typically requires on-premises hardware on both ends, as well as client software. But what about the at-home worker, or the employee who is traveling around the world on business and needs to stay in touch with the home office? An SSL (Secure Sockets Layer) VPN is better suited to this purpose.

The SSL VPN, because it does not require additional hardware on the client side and no additional client software, is useful for situations where a secure connection must be made on an ad hoc basis from multiple locations. The SSL protocol is built into most web browsers, which makes connectivity very simple and straightforward.

Access Control

Regardless of the type of VPN service, access control is an important element. You are opening up your network to an external location or multiple external users, but in most cases, you will not want to allow unlimited access to the entire network. The IPSec VPN, as a site-to-site technology, has the potential to offer connectivity to the entire network, although precise authentication and authorization controls will regulate what can be accessed based on an individual or role-based set of rules. SSL VPNs on the other hand, are configured for only individual, web-based applications, rather than the whole network.
