I've searched and there don't seem to be many threads that focus/relate to a products ease of management when you're talking a few hundred machines. So far I've looked at Kaspersky, NOD32 and F-Secure and all have pros and cons. Realistically I can't look at every single vendor out there, and what might be a fantastic product installed on a single PC may not be a fantastic product if the central management is a dog. Other than the three I've listed, does anyone have any recommendations of a product that is not only an excellent client product, but that also has good central management and monitoring? Some of the features on my wish list are: By default grab updates from LAN management box, if that's not available (i.e. a laptop away from the office default to check the vendors website). Report unknown applications accessing the internet, or acting as a server. Allow blocking of individual applications that try and access the Internet i.e. Skype. Light client footprint - I want something that just sits in the system tray until there's a problem, no confusing pop-ups/windows every time something happens etc. Excellent spyware/web threat detection. A location aware firewall would be useful i.e. let everything in/out on our LAN but default to blocking inbound connections the rest of the time (user-selectable). Windows XP 64 bit support.
