We performed a comparison between Tenable Nessus and Acunetix based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison results: Based on the parameters we compared, Tenable Nessus comes out ahead of Acunetix. Even though both solutions offer beneficial vulnerability scanning and a proactive approach, Acunetix’s two-year licensing plan is less flexible than that of its competitor, and its need for manual resolution of false positives leaves room for improvement.
"We use the solution for the scanning of vulnerabilities like SQL injections."
"I haven't seen reporting of that level in any other tool."
"The automated approach to these repetitive discovery attempts would take days to do manually and therefore it helps reduce the time needed to do an assessment."
"Acunetix is the best service in the world. It is easy to manage. It gives a lot of information to the users to see and identify problems in their site or applications. It works very well."
"The scalability is good. The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications. So that really makes it a very, very versatile solution to have."
"For us, the most valuable aspect of the solution is the log-sequence feature."
"The most valuable feature of Acunetix is the UI and the scan results are simple."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"The solution is the most dynamic one I have seen thus far."
"I like this solution because it is complete. It can scan and check many types of vulnerabilities. It can also check for compliance."
"Overall Zoom is a good solution."
"Tenable Nessus is cheap and flexible."
"Once you get past the initial implementation, the solution is very stable."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The trial version is very good for testing whether it will suit your needs."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"Currently only supports web scanning."
"We want to see how much bandwidth usage it consumes. When we monitor traffic we have issues with the consumption and throttling of the traffic."
"While we do have it integrated with other solutions, it could still offer more integrations."
"Acunetix needs to include agent analysis."
"The solution limits the number of scans. It would be much better if we could have unlimited scans."
"The only problem that they have is the price. It is a bit expensive, and you cannot change the number of applications for the whole year."
"The pricing is a bit on the higher side."
"Acunetix needs to be dynamic with JavaScript code, unlike Netsparker which can scan complex agents."
"The inventory management function in this solution needs improvement."
"Model OS costs (and its segregation schema for individual modules)."
"They need more flexible pricing."
"Remediation needs improvement."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."
"The reporting is a bit cumbersome."
"Nessus' reporting could be more user-friendly."
