Tenable offers a VM appliance which has Nessus on it to ProfessionalFeed customers. Aside from that, Nessus is just like any other application and if you don't give it enough disk space, cpu or memory you'll impact performance. Having said that, we have a lot of customers that run stand-alone Nessus scanners with 1GB of memory. We also have some customers that deploy Nessus on 4GB, 8GB, .. 16GB systems to scan multiple ClassBs, perform 100s of web apps at the same time, perform 1000s of scans for an MSP offering, .etc. I do a lot of testing of Nessus and our SecurityCenter product and tend to run them both in VMs or Amazon instances with 2GB of memory and regularly scans ClassBs, do web app audits, .etc. -- Ron Gula, CEO Tenable Network Security http://www.tenable.com _______________________________________________ Pauldotcom mailing list [email protected] http://mail.pauldotcom.com/cgi-bin/mailman/listinfo/pauldotcom Main Web Site: http://pauldotcom.com
