A method comprising: receiving a request to open unverified content from a remote server; determining, by an application resolver without user intervention, that the unverified content is designated for opening in a disposable environment; causing the unverified content to be uploaded to a cloud file storage; automatically instructing a virtualization server to provision a temporary virtual machine in the disposable environment to open the content uploaded into the cloud file storage; receiving a confirmation from the virtualization server that the temporary virtual machine in the disposable environment is ready to connect; launching a client agent on a user device, the client agent being configured to communicate using at least a remote presentation protocol with the temporary virtual machine associated with the virtualization server; connecting, using the client agent on the user device, to the temporary virtual machine in the disposable environment; displaying, by the client agent on the user device an output resulting from opening of the unverified content at the temporary virtual machine in the disposable environment; responsive to a determination that the unverified content is benign: opening the unverified content; and transferring the display from the output resulting from the opening of the unverified content at the temporary virtual machine to a locally-generated graphical user interface resulting from the opening of the unverified content at the user device; and terminating the connection with the temporary virtual machine in the disposable environment. receiving a request to open unverified content from a remote server; determining, by an application resolver without user intervention, that the unverified content is designated for opening in a disposable environment; causing the unverified content to be uploaded to a cloud file storage; automatically instructing a virtualization server to provision a temporary virtual machine in the disposable environment to open the content uploaded into the cloud file storage; receiving a confirmation from the virtualization server that the temporary virtual machine in the disposable environment is ready to connect; launching a client agent on a user device, the client agent being configured to communicate using at least a remote presentation protocol with the temporary virtual machine associated with the virtualization server; connecting, using the client agent on the user device, to the temporary virtual machine in the disposable environment; displaying, by the client agent on the user device an output resulting from opening of the unverified content at the temporary virtual machine in the disposable environment; responsive to a determination that the unverified content is benign: opening the unverified content; and transferring the display from the output resulting from the opening of the unverified content at the temporary virtual machine to a locally-generated graphical user interface resulting from the opening of the unverified content at the user device; and opening the unverified content; and transferring the display from the output resulting from the opening of the unverified content at the temporary virtual machine to a locally-generated graphical user interface resulting from the opening of the unverified content at the user device; and terminating the connection with the temporary virtual machine in the disposable environment.
