Virtual air-gapped endpoint, and methods thereof

An air-gapped computing system includes at least network card interface; a processing circuitry; and a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to: initialize a hypervisor for execution over a primitive OS; create a plurality of isolated security zones by instantiating a plurality of corresponding virtual machines using the hypervisor, wherein each of the plurality of security zones includes a plurality of applications executed over a guest OS; instantiate a networking virtual machine using the hypervisor; control, by the networking virtual machine, access of each application in each of the plurality of security zones to an external network resource; and monitor execution of the guest OS and each application in at least one activated security zone of the plurality of security zones, wherein the monitoring is performed to maintain compliance with a security policy corresponding to each activated security zone being monitored.
