Security (MS)

Brief description of the Client Security Enterprise Manager:

Forefront Client Security Enterprise Manager provides administrators the ability to manage multiple Client Security deployments from a single server.

After you install Enterprise Manager you are able to centrally manage:
1. Client Security policy deployment.
2. Alerts from Client Security agents in the entire enterprise.
3. Reports from all Client Security deployments in the Enterprise Manager organization.

Not only is it a good idea, it is practically required due to how the MOM 2005 backend scales.

Pretty cool if you ask me. Sort of like the Home Use license, but better.

To quote the post here:
Customers who license the Client Security agent on a per-user basis can provide the Client Security agent to employees at no additional cost for protecting home computers. These home-based Client Security agents must be deployed in an unmanaged configuration; they will not be able to report to your Client Security servers in your enterprise.

Installing the client without the management portion is very easy - as simple as clientsetup.exe /nomom.
