Identifies vulnerabilities across bulk web applications but needs better support and cleaner reports
The best feature Acunetix offers is the centralized dashboard and the quality of reports it generates, which includes various options for selecting reports and developer options for directly sharing the reports with developers. The centralized dashboard of Acunetix gives visibility into the security aspects of mass applications; for instance, with more than 200 applications, it provides a valuable overview of findings and necessary fixes, along with a high-level summary that helps us achieve compliance through monthly and sometimes weekly scanning. In terms of reporting, Acunetix is excellent because it can generate different types of reports, such as an executive summary report, detailed reports, and developer reports that can be shared directly with developers. Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and OWASP. Acunetix provides a centralized report with compliance-related aspects and a vulnerability timeline, effectively helping reduce vulnerabilities and save time.

Centralized license management transforms asset manipulation based on functions and improves security posture
Now that the license is centralized, it's a significant feature to manipulate assets based on their functions. It provides a centralized view from end-to-end to its assets' identities and vulnerabilities. One of the greatest features is Kubernetes. The automated scanning capability is pretty standard in the market, and Tenable's prioritization engine helps improve the security posture.

Quotes from Members

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

Pros

"Acunetix helps reduce the man-days and effort needed for scanning bulk applications through automated assessments, allowing good dashboard visualization that can be reported easily to management, providing complete visibility on vulnerability metrics."
"Our developers can run the attacks directly from their environments, desktops."
"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 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."
"The tool's most valuable feature is scan configurations. We use it for external physical applications. The scanning time depends on the application's code."
"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."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"Overall, it's a very good tool and a very good engine."
"The initial setup is straightforward."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"All the features are valuable to us as they offer cutting-edge scanning methods and address the latest issues with a contemporary approach. Tenable.io Web Application Scanning is highly stable. I rate it a nine out ten. Since the solution works on the Cloud, it's highly scalable. I rate the scalability a nine out of ten. The setup of the solution is straightforward. The Return on Investment is substantial. I recommend the solution to all."
"The most effective feature of the product is the ability to scan the entire environment."
"The solution is stable."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"The most valuable features of Tenable.io Web Application Scanning are the integration into specific use cases and scanning. All of the features of the solution are useful."
 

Cons

"There's a clear need for a reduction in pricing to make the service more accessible."
"I believe Acunetix can improve customer support, as the dedicated support staff are often unfamiliar with problems and troubleshooting, leading to communication gaps that delay issue resolution."
"I believe Acunetix can improve customer support, as the dedicated support staff are often unfamiliar with problems and troubleshooting, leading to communication gaps that delay issue resolution."
"The jargon used makes it difficult for project managers to understand the issues, and the technical explanations used make it difficult for developers to understand issues. These things should be simplified much more. That would be very helpful for us when explaining to them what needs to be fixed. The report output needs to be simplified."
"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."
"I believe Acunetix can improve customer support, as the dedicated support staff are often unfamiliar with problems and troubleshooting, leading to communication gaps that delay issue resolution."
"There was an issue related to updates from the internet."
"The solution limits the number of scans. It would be much better if we could have unlimited scans."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."
"Tenable.io Web Application Scanning is not very user-friendly and you need a lot of information to get proper reports. The tool's support is not very responsive."
"Sometimes it lags with different cloud environments."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"The reporting has a very limited customization capability."
"The report customization needs to be better."
"The technical support needs improvement. Currently, it takes time, which might be due to the free version, but providing some level of support could encourage future purchase decisions."
 

Pricing and Cost Advice

"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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."
"When compared with other products, the pricing is a little bit high. But it gives value for the price. It serves the purpose and is worthwhile for the price we pay."
"It is a bit expensive. If you need to check five applications, you have to pay almost 14,000. It is an agreement for two years at 7,000 per year for only five applications. You cannot change the applications in the license. So, you are stuck with the same license for the five applications for one full year."
"The price is exceptionally high."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"The pricing is okay."
"I rate the product's pricing a four out of ten."
"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."
"Tenable.io Web Application Scanning is expensive for small businesses."
"The price of the solution is reasonable compared to the competitors. The license cost is based on the number of users and the annual usage."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
