# Standalone or Enterprise CA

Intel SCS supports the Standalone and Enterprise versions of Microsoft CA. An Enterprise CA can be configured only in conjunction with Active Directory. A Standalone CA can operate with or without Active Directory. The Microsoft CA can have a hierarchy of CAs, with subordinate CAs and a root CA. This is beyond the scope of this guide.

These features require a Standalone root CA or an Enterprise root CA:

- Transport Layer Security (including mutual authentication)
- Remote Access with password-based authentication

These features require an Enterprise root CA:

- Remote Access with certificate-based authentication
- 802.1x setups (Wired or WiFi)
- EAC settings
