When looking at a PC in Lansweeper there are various tabs available (Software, Config, Event, etc). An idea I thought was to add a tab called 'Security'.
Under this tab we may see Antivirus Status, Windows Update Status, Firewall Status, Unauthorized Admins, Local users, Current Logged on User or history, Encrypted Hard Drive status, Security Event Log, or anything potentially security related.
I don't know if this could be an easy task...especially the Firewall status since the firewall could be Windows or another vendor.
Just a thought.
