Whats the difference between it and ISS and other remote scanners?
ISS, and any other remote auditing tool that we’re aware of, scans a network or remote host and then reports on any problems that it may find. While SATAN does that as well, the inferencing, the web of trust that it uncovers, the automatic probing of secondary targets, the rich reporting schema with context sensitive hypertext links to the documentation, the rich configurability, etc. all make SATAN different to what is currently available.
