A cloud computing platform provides zero trust network access as a service to customers that maintain applications on-premises. In this context, the cloud computing platform may associate customers and/or applications with specific service proxies, and add an abstraction layer for network access that maps an alias domain for each customer and/or application to a network load balancer associated with the specific service proxies associated with the corresponding application(s). This approach advantageously simplifies the configuration of service proxies at the cloud computing platform by permitting dedicated relationships among network load balancers, specific service proxies, and specific applications, while concurrently reducing or avoiding the administrative burden on customers of updating network pointers when the clusters of service proxies are periodically reconfigured to adjust to varying user traffic.

Alias domains for accessing ZTNA applications

Infrastructure for zero trust network access (ZTNA) is deployed as a cloud-based service remotely from a customer premises where user applications are hosted. By connecting an appliance on the customer premises to the cloud-based service through a secure tunnel or the like, an application hosted on the customer premises can then be accessed externally as a ZTNA application without the customer premises opening a firewall to public networks or otherwise exposing potential attack surfaces to the customer premises.

Cloud-based zero trust network access service

A cloud-based platform for zero trust network access (ZTNA) services provides zero trust network access as a service for multiple customers in a multi-tenant architecture. In this context, the configuration for a new ZTNA application is validated with a service proxy in a sandbox or similar environment before release by the cloud-based platform for access through a public network. As a significant advantage, this approach mitigates inadvertent conflicts or instability in a service proxy that supports other applications and customers.

Validation of ZTNA configuration for a multi-tenant proxy environment

A method includes receiving, by a computer system, information related to device health of an electronic device, determining, by the computer system, a health status of the electronic device based at least in part on the received information related to the device health of the electronic device, requesting, by a switch having a port connected to the electronic device, the health status of the electronic device from the computer system, receiving, by the computer system, the request for the health status of the electronic device from the switch, transmitting, by the computer system, the health status of the electronic device to the switch, evaluating, by the switch, the transmitted health status of the electronic device using network access rules associated corresponding to health statuses, and applying, by the switch, a network access control configuration to the port of the switch based on the evaluating the transmitted health status.
