The types of CA

Based on the installation mode, CAs can be divided into two types: the Standalone CA and the Enterprise CA. The best way to explain the capabilities of both types is to compare them:

Feature	Standalone CA	Enterprise CA
AD DS dependency	Does not depend on AD DS; can be installed on a member server or standalone server in a workgroup	Can only be installed on a member server
Operate offline	Can stay offline	Cannot be offline
Customized certificate templates	Does not support; only supports standard templates	Supported
Supported enrollment methods	Manual or web enrollment	Auto, manual, or web enrollment
Certificate approval process	Manual	Manual or automatic based on the policy
