Featured Reviews

SimonClark - PeerSpot reviewer
Able to discover unpatched servers, offers good stability, and scales very well
A low-cost service to evaluate the risk score of a supply chain would be very helpful. This could be useful for insurance companies offering cyber insurance to enterprise customers, providing the insurer with a valuable way to unobtrusively, quickly, and frequently assess their customers and apply appropriate premiums for the level of risk. This would also be useful for enterprises. They could, for example, assess companies prior to a merger or acquisition. What would also be useful for any enterprise would be if their supply chain has some kind of direct digital access to parts of their network.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is stable with 12 years of established historical data."
"The initial setup of Tenable Nessus is very easy."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The solution is easy to understand for users because instructions are included on the platform."
"I like the fact that it was not expensive. I like that it's user-friendly."
"The support has been really cooperative."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"The most valuable feature of Tenable Nessus is real-time monitoring."
 

Cons

"A low-cost service to evaluate the risk score of a supply chain would be very helpful."
"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."
"They need more flexible pricing."
"We would like to have the option of using the solution for the cloud as well as on-premises with the same license at the same time. That would be very helpful."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"Vulnerability recommendations are outdated and not in line with industry standards."
"The scalability of Tenable Nessus is good. However, it could be more flexible."

"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
