NessusWC provides a simple HTTP Web interface to the Nessus Security Scanner. It connects to local or remote Nessus version 2 daemons via SSL (using OpenSSL libraries), retrieves the plugins, configures a scan for a single target host, and saves the results in HTML format. As a result, even users with limited security knowledge can scan their machines. Scan results are stored in a central place. License: GNU General Public License (GPL) Changes:
Correct error handling was implemented for when the Nessus server plugin list exhausts the maximum number of plugins defined in NessusWC. The MAXPLUGS default value was raised from 20000 to 40000. This was noticed when the plugin count reached 20667.

Hey u know :
1. How much time is required to perform a scan on (say 4000) list of hosts when parallel scan is being scheduled?

2. Is there any way to schedule sans through Nessus??
