1. A network isolation device comprising:
an internal network interface to connect the network isolation device to an internal network;
an external network interface to connect the network isolation device to an external network;
an airgap device that operates to (i) close an air gap to connect the internal network to the external network, and (ii) open the air gap to disconnect the internal network from the external network; and
a signal receiver comprising one or more processors executing instructions that cause the signal receiver to:
receive a message from a user of a group of multiple users, the message including an access code;
authenticate the message based at least in part on the access code; and
in response to receiving and authenticating the message from the user of the group of multiple users, make the internal network accessible to the group of multiple users over the external network by closing the airgap device, so as to and connect the internal network to the external network.
