An Internet-based virtual private network (VPN) uses the open, distributed infrastructure of the Internet to transmit data between sites. A virtual private network can be contrasted with a system of owned or leased lines that can only be used by one company. The idea of the VPN is to give the company the same capabilities at much lower cost by using the shared public infrastructure rather than a private one. Using a VPN involves encrypting data before sending it through the public network and decrypting it at the receiving end. An additional level of security involves encrypting not only the data but also the originating and receiving network addresses. Companies today are looking at using a VPN for both extranet and wide-area intranet.
The fundamental requirements that VPN service must address are security, management, and quality of service. Clients using VPN services demand the same level of security they have come to expect using traditional leased-line private networks. The layered dynamic security employed by the WeGuardYou system provides a secure “pipeline” of communications between client locations. This sanctuary from data attacks is entirely secure due in part to its client interactivity and dynamically shifting encryption structure.
Management is a set of mechanisms that allow a VPN client to control and manage the use of network resources based on the application or end user. The solution must include client management capabilities such as real-time reporting. Additionally flexibility to tailor the solution is key. WeGuardYou’s VPN solution provides the user with custom reporting for multiple applications, and dynamic flexibility for all client applications that reduce traditional management overhead.
