One of the best vulnerability scanners on the market **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** October 24, 2024 **What do you like best about Tenable Nessus?** 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 Tenable Nessus?** 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 Tenable Nessus solving and how is that benefiting you?** It finds and categorizes all vulnerabilities on all device types.

Most of the scanners have licenses per IP, so if you have wide ip ranges, licenses fee would be astronomious. You will need to accomodate the limited reporting and vulnerability management feature of the proffessional version. **What do you dislike about Tenable Nessus?** Nessus Professional need some good process OR automation to get the most of it as you dont have any 'quality of life' feature like dashboard, tracking and limited automation. **What problems is Tenable Nessus solving and how is that benefiting you?** Tenable Nessus solves problems related to cybersecurity, primarily by helping organizations identify vulnerabilities in their networks, systems, and applications.
