Use Cases and Deployment Scope
We use Isec (Ivanti Security Controls) for our monthly security patching of all servers in the environment (on-prem). This allows us to keep our servers up to date with the monthly release cycles from Microsoft and other vendors. It's also used for ad-hoc patching as needed for zero-day threats as well as keeping our template builds up to date.
