US Army officials are looking to develop a new slate of zero trust software for use on the service’s tactical networks as a way to further insulate battlefield command, control, and communications operations from rapidly maturing cyber threats.

Industry proposals for tactical zero trust software are due to programme officials at the army’s Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) Center by 15 March, with the end goal of developing network software that aims “to address the [zero trust] activities for the tactical environment to as far down into the network as feasibly possible”, according to a 5 March solicitation.

Commercial and government networks developed within a zero trust architecture operate under the assumption that an organisation’s networks are not just at risk of a cyber intrusion, but that they are already compromised.
