Forefront Client Security is an enterprise-level antimalware offering. As part of a total security solution, Client Security protects your client computers from malware threats in the enterprise. 

Threats don’t always come from the world outside your firewall.  Your users may be unknowingly bringing malware into the work environment by bringing in items as innocuous as pictures.  Enabling users to protect their home computers from malware threats could reduce the incidence of malware in your enterprise.

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.
