The risk is worse than that -- a malicious party having access to a box which can view and modify 100% of your outside traffic is a very ugly scenario. There is of course much more to security than running ISS. > 10) ToD: All boxes have the ability to control based on source IP, > destination IP and port.

And hopefully all the data would be SNMPable so you can do your own graphs as well. As with all networking products, the key for an ISP environment is not to provide an all-in-one solution but to provide something with good plugs so it integrades well with the rest of your network. -- Shields, CrossLink.
