What do you like best about the product?

Nessus was very easy to install, and we were up and running in very little time. There are lots of various scan type options to choose from. Our third party auditors also use Nessus for internal vulnerability scans, and we were able to import their scanning template in order to do accurate post remediation scans. We were able to easily setup a weekly scan schedule. Product updates are simple and straight forward, and we recieve notification when new versions are available. The price was also within our budget.

What do you dislike about the product?

I wish Nessus had a vulnerability remediation option. Finding all the detailed vulnerabilities is only half the battle, researching the vulnerability and the fix is also time consuming. Nessus does have links to the CVE or KB docs, and many times remediation reccomendations, but the patching process is still manual. I realize that automatic remediation may not always be the best practice depending on the vulnerability, the system/device, and various other factors, but possibly some options for simple patches would be very useful.

What problems is the product solving and how is that benefiting you?

It finds and categorizes all vulnerabilities on all device types. Our previous product would only work with Windows devices for instance, so you are not getting a complete picture of your entire network. Vulnerabilities are categorized based on criticality, so you can prioritize your remediation process.
