What is a Mac OS X equivalent of McAfee Security network mapping? We have multiple computers of different OS in a network. Mine is Mac OS X and most others are Window XP or 7.  I will need to help monitor what computer gets connected. In past, I use Windows and have McAfee security which products a real-time map of all connected computers including each IP and Computer name. 

Now using Mac OS X, I find nothing I can use. I tried nmap and Zenmap, but neither provides computer name, and neither is real-time monitor and scanning takes forever. There is NetworkView but it only works on Window machines.

What can I use?
You can try ProteMac. I have no experience with this software bundle, but it looks like it does what you are looking for!
