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.
"For us, the most valuable aspect of the solution is the log-sequence feature."
"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."
"The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution."
"Overall, it's a very good tool and a very good engine."
"The usability and overall scan results are good."
"Picks up weaknesses in our app setups."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"I am impressed with the tool's vulnerability scanning."
"A valuable feature of the solution is that it is easy to understand."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
"User friendly and good dashboards."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"Tenable Nessus is an absolutely stable and fantastic product."
"There is room for improvement in website authentication because I've seen other products that can do it much better."
"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."
"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."
"You can't actually change your password after you've set it unless you go back into the administration account and you change it there. Thus, if you're locked out and don't remember your password, that's a thing."
"The pricing is a bit on the higher side."
"Integration into other tools is very limited for Acunetix. While we're trying to incorporate a CI/CD process where we're integrating with JIRA and we're integrating with Jenkins and Chef, it becomes problematic. Other tools give you a high integration capability to connect into different solutions that you may already have, like JIRA."
"I had some issues with the JSON parameters where it found some strange vulnerabilities, but it didn't alert the person using it or me about these vulnerabilities, e.g., an error for SQL injection."
"The solution limits the number of scans. It would be much better if we could have unlimited scans."
"It would be nice for the professional module to include some of the reports available in the expert module."
"EQA's and dashboards should be addressed in the next release."
"This is still a maturing product. Tenable is only a scanner for one ability, while other solutions like Rapid7 have more tools for verification. We still have to manually verify to see if the vulnerability is a false positive or not."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"Consumes more system resources when it's running."
"I think the reporting templates could be improved with Tenable Nessus."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"Scans aren't done properly and some devices aren't pinged."
