Information Technology Risk to an organization is associated with a plurality of virtual machines (VMs) each running on a plurality of hosts, each host being a computer system connected to a network and in communication with a risk orchestrator, which receives threat indication messages (TIMs) from threat indicators. Each TIM indicates a status of a threat to which a hosts is vulnerable. Downtime probability (DTP) resulting from the threat and an overall host DTP for each host are calculated. For each VM, a risk value associated with the VM is calculated as a function of the host DTP for and an impact for the VM, the impact being a value reflecting a relative importance of the VM to the organization. Each VM requiring risk mitigation is identified and prioritized in accordance with a policy, and a configured mitigation control action may be carried out for each VM requiring risk mitigation.
