Deployment Topology
VPS can be implemented as an appliance installed on the corporate network or as a service hosted by Navajo Systems or a third-party service provider.
VPS Installed as a Network Appliance
In this deployment approach, VPS is installed on the corporate network, behind the firewall, and serves as a proxy server between browser agents (and other components which interact with the SaaS application) and the application server. Remote employees may connect to VPS as installed on the network via VPN to enable secure application access from outside the corporate network.
VPS as a Service
In this deployment approach, a dedicated VPS device is hosted on the cloud and is accessed via VPN. VPS serves as a proxy server between browser agents (and other components which interact with the SaaS application) and the application server. In this deployment scenario, both users inside the corporate network and remote users have seamless access to the encrypted SaaS data. To protect against identity theft in this approach, either SSL VPN or advanced two-factor authentication can be used.
