Quotes From Members

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

Pros
"One of the features that I feel is groundbreaking, that I would like to see expanded on, is the IAS feature: The Interactive Application Security Testing module that gets loaded onto an application on a server, for more in-depth, granular findings. I think that is really neat. I haven't seen a lot of competitors doing that.""The most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great.""Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick.""We are able to create a report which shows the PCI DSS scoring and share it with the application teams. Then, they can correlate and see exactly what they need to fix, and why.""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.""The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution.""Our developers can run the attacks directly from their environments, desktops.""It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."

"They also have threat detection which maps threats. There is a feed that comes from Qualys when a new vulnerability is found. It tells us which machines are infected with that vulnerability.""The most valuable feature is the certificate management."

"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three.""Tenable Nessus streamlines the process of scanning for our organization.""I find the features that are most valuable are the policies that help us identify the vulnerabilities. These policies are then used for scanning instabilities and then identifying the particular vulnerabilities.""The solution is very stable.""The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing.""Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully.""It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can.""Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."

Cons
"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.""It should be easier to recreate something manually, with the manual tool, because Acunetix is an automatic tool. If it finds something, it should be easier to manually replicate it. Sometimes you don't get the raw data from the input and output, so that could be improved.""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.""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.""It would be nice to have a feature to "retest" only a single vulnerability that the customer reports as patched, and delete it from the next scans since it has already been patched.""In terms of what needs improvement, the way the licensing model is currently is not very convenient for us because initially, when we bought it, the licensing model was very flexible, but now it restricts us.""Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS.""When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."

"What we have found is that the solution is not closely tied with the patch management. It is okay with newer ones, like Windows 10 machines; it gives the correct patch. But for Windows 7 or Windows Server 2008, it does not give us the correct patch so we have to manually identify the patches. This is a major problem.""The reporting in this solution can be improved."

"From my point of view the solution basically is not for the big enterprise.""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.""We have had some false positives in the past, which we hope can improve in the future.""I would like to see an improvement in the ranking of high, medium and low vulnerability.""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.""One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that.""We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux.""There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."

Pricing and Cost Advice
"When we looked at all other vendors and what they were asking for, to provide a third of what Acunetix was capable of doing, it was an easy decision... But now that it's coming to a cost where it's line with market value, it becomes more of a competition... Acunetix is raising the cost of licensing. It's 3.5 times what we were initially quoted.""Acunetix was around the same price as all the other vendors we looked at, nothing special.""The pricing and licensing are reasonable to a point. In order to run multiple scans at a time, we are going to have to purchase a 100 count license, which is an overkill. Though, compared to what we were paying for, the cost seems reasonable.""All things considered, I think it has a good price/value ratio.""The costs aren't very expensive. It costs around $3000 or $4000.""I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced.""The pricing is a little high, and moreover, it's kind of domain-based."

"The pricing is much more manageable versus other products.""The price of Tenable Nessus is much more competitive versus other solutions on the market.""I think the price is fairly affordable. It provides a license that is fair."
