The use it is given and the categorization of vulnerabilities are also important. **What do you dislike about Tenable Nessus?** The price of the PRO version is too high for it to be just a vulnerability scanner. Also, the automatic reports should improve.

Nessus is the ultimate time saver for vulnerability scanning **Rating:** 4.5/5.0 stars **Reviewed by:** Gihan J. | Penetration Tester, Enterprise (> 1000 emp.) **Reviewed Date:** November 28, 2019 **What do you like best about Tenable Nessus?** As a penetration tester there were times that I had to perform operating system compliance reviews manually. To do that you have to go through all the documented details in benchmarks to get a crystal clear idea before even executing the given command. Reading issue details on over 500+ pages (most of the time) repetitively is a waste of time . Because of the tool 'Nessus' we can just pass the parameters and actually can let our focus on other operations. Nessus will do the job without any trouble. Incontrovertibly, nessus is the number one performer in discovering assets,sensitive data /malware detection,OS/database/mobile apps/web apps/network devices/tablets/hypervisors vulnerability scanning.It's worth to mention the amazing report creation feature of nessus which helped me to identify the critical levels of the vulnerabilities easily. **What do you dislike about Tenable Nessus?** Price of nessus is too much considering the tools in the same domain.

Nessus Vulnerability Scanner **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Management Consulting | Enterprise (> 1000 emp.) **Reviewed Date:** July 31, 2018 **What do you like best about Tenable Nessus?** The Nessus vulnerability scanner from Tenable offers excellent vulnerability and compliance scanning coverage. The API offers good flexibility for developing custom solutions. Coupled with other Tenable products, such as Tenable.io, SecurityCenter, or NessusManager provides centralized management and reporting. **What do you dislike about Tenable Nessus?** Nessus on its own is a solid product but does require some customization of the settings to run more efficiently. **Recommendations to others considering Tenable Nessus:** The Nessus scanner by itself is a great tool and has a large number of plugins and vulnerability coverage. The basic reporting is acceptable but is much more robust and customizable when coupled with other products. Tenable support has dramatically decreased over the past several years. I frequently find myself having to do half their job of testing the product. More often than not, we have to solve the problems on our own (and usually through some sort of custom development/workaround). **What problems is Tenable Nessus solving and how is that benefiting you?** Nessus is one of the tools that we use within our vulnerability management program. It has helped us ensure patches are being deployed in a timely fashion, find systems vulnerable to specific issues, and ensure system builds are compliant with our security baselines. We also leverage the built-in web application checks to monitor our websites (in addition to running dynamic scans with a purpose-built web vulnerability scanner). ### 35. Nessus Security Platform - Vulnerability Management **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** January 01, 2022 **What do you like best about Tenable Nessus?** Nessus is one of the most straightforward tools available to handle VMS operations. Low budget enterprise tool which every organization can afford. Nessus VA scan covers all standard network devices like endpoint, servers, network devices, virtualization platforms as well as a cloud environment. They provide plugins for every vulnerability and can scan with authenticated or unauthenticated scans. It is straightforward to use, generates an excellent report (various options available to customize). **What do you dislike about Tenable Nessus?** If you compare Nessus to other VM tools like Nexpose or Qualys, Nessus has minimal features, and customization & Integration in Nessus is also not very helpful for organizations, where they need to customize their data set per their requirements. Vulnerability fingerprinting also needs some enhancement. For some devices like Cisco, it flagged the exposure based on the iOS version running on the target machine but not based on the vulnerable configuration present on the device. Which further needs manual assessment to validate if the fingerprinted vulnerability is false positive or not. **What problems is Tenable Nessus solving and how is that benefiting you?** Frequent and constant product updates. Easy to use, configurations are not overly complex. Reasonable price compared to other players. ### 36.
