"Endpoint" security solutions?

[spencerforhire <spencerforhire () gmail com>]

Hello,

I'm looking for advice on endpoint security solutions which address
the security of intellectual property - e.g. monitoring and reporting
of suspicious removable storage and webmail activity.  Some of the
endpoint security solutions I've seen focus on antivirus and patch
compliance, but I would like some options that address suspicious
handling of corporate information.  The ability to centrally manage
endpoint agents is also important since I envision them being
dispersed across many physical locations.  I heard Altiris had a
product that might fit these requirements, but it was purchased by
Symantec and I'm not sure of the current status?

Thanks!

Mark
