Abstract: A system is provided to deliver an application, hosted by a private application provider system, over a network to a user device, comprising: an application delivery system that includes a first network interface, a network security interface and a second network interface; wherein the network security interface is configured to determine whether a user or device request for access to an application is valid, and in response to determining that the user or device request for access to the first application is valid, to send the user or device request to the application agent.

Abstract: A system is provided comprising: an application delivery system that includes, a first network interface, a network security interface, and a second network interface; an agent is disposed within one or more private application provider systems; a security network interface instance determines whether a received request is valid, and in response to determining that the received user or device request is valid, to send the received request to a respective second network interface instance for delivery to the agent.

Abstract: A system is provided to deliver an application, hosted by a private application provider, over a network to a user device comprising: an application delivery system that includes a first network interface, a network security interface, and a second network interface; an application agent is disposed within the private application provider system. wherein the first network interface receives an encrypted user or device request for access to the hosted application sent over the network and to send the user or device request to the network security interface; wherein the network security interface is configured to decrypt the request, to validate request, to re-encrypt the request and to send the encrypted request to the second network interface; wherein the second network interface is configured to send the encrypted request over the network to the agent; and wherein the agent is configured to send the request to the hosted application.

Abstract: A system is provided to deliver an application, hosted by a private application provider, over a network to a user device comprising: an application delivery system that includes a plurality of first network interface instances, a plurality of security interface instances, a plurality of second network interface instances; multiple application agents, disposed within one or more private application provider systems; a first information structure associates first network interface instances with one or more security interface instances; a second information structure associates second network interface instances with one or more security interface instances; wherein first network interface instances are configured to create a network connections with associated security interface instances and to send requests to the associated security interface instances; wherein second network interface instances are configured to have pools of network connections with one or more agents and to have corresponding connection
