ABSTRACT
VPNs and their many benefits, however, have traditionally been the domain of larger organizations. These huge companies enjoy access to the capital and scale necessary to build VPNs and have the technical staff to maintain them. They are able to use VPNs to enhance and sustain their competitive advantage over their smaller and less technically sophisticated competitors. In practical terms, the benefits of VPNs have been off limits to small-and medium-sized businesses. And, even larger organizations have had difficulty deploying VPNs in branch offices because they are often too small to justify on-site IT staff.
