Abstract: A secure socket layer virtual private network (SSL VPN) network appliance includes a set of virtual systems having respective context information. Each of the virtual systems represents a VPN for a different subscriber network. The network appliance includes a network interface to receive a first network communication associated with a first one of the virtual systems. In response to the network communication, the SSL VPN network appliance sets a context identifier that identifies the first one of the virtual systems. The network appliance further comprises a set of VPN software processes executing on the network appliance to process the first network communication, wherein the set of VPN software processes generate data access requests. A configuration access application programming interface (API) dynamically directs the data access requests from the VPN software processes to the first one of the virtual systems based on the context identifier.

Abstract: A scalable enterprise computer system having the capability to provide transaction security as well as providing subscription filtering is described.
