A server is said to be Patch compliant on IG when there is no Security or Critical patches pending to be installed.

By default, IG separates patches based on critical/security and notifies you when a patch of the same category is available for installation. Further IG offers a custom dashboard to let you pick patches on demand. 

Baselines can be created on IG with help of policies. You have the freedom to create any number of policies and assign it to servers of your choice. These policies are OS and Cloud platform agnostic.
