What is Dark Site Licensing?
Dark site licensing refers to licensing configurations designed for deployment in environments that are permanently or semi-permanently disconnected from the public internet, sometimes called 'dark sites.' These environments, common in defense, energy, and classified government settings, cannot use cloud-based license validation at any point in the software lifecycle. Dark site licensing typically relies on pre-provisioned license files, hardware security tokens, or locally hosted license servers that are configured before the site goes offline and operate independently for the duration of the license term.
Examples
- A defense contractor deploys software to a forward operating base with no internet access; licenses are pre-loaded on a portable license server before the server is shipped to the site.
- An oil and gas company runs specialized analysis software on an offshore platform with no satellite connectivity; the vendor provides an extended offline license file valid for 12 months.
- A government agency operates a processing facility that never connects to any external network; software licenses are provisioned during infrequent site visits by the vendor's field team.
- A satellite ground station operator uses dark site licensing with a locally hosted license server that synchronizes during brief maintenance windows and operates offline between them.
Common Applications
- Military and defense forward deployments and classified facilities
- Offshore energy platforms and remote industrial installations
- Government and intelligence environments with permanent network isolation
- Disaster response systems designed to operate without infrastructure dependency
- Research stations and polar expeditions with long-duration offline operation requirements
