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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"I find it to be one of the most comprehensive tools, with support for manual intervention."
"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 solution is highly stable."
"The product is really easy to use."
"Our developers can run the attacks directly from their environments, desktops."
"It generates automated reports."
"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."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"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."
"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."
"It has good unified web application scanning and exposure management."
"It is fully automated."
"The solution's instant reports feature is the most effective for detecting threats."
"I think Tenable.io Web Application Scanning is the best option on the market at the moment."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
 

Cons

"The solution is generally stable, however, there might be room for improvement regarding glitches or bugs."
"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."
"I think Acunetix needs improvement since it is now working with Invicti, so the price list will need to be reconsidered."
"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."
"I rate its stability six out of ten."
"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."
"The solution limits the number of scans. It would be much better if we could have unlimited scans."
"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."
"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."
"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."
"The report customization needs to be better."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"It isn't easy to manage vulnerabilities in Tenable."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"The platform's technical support services could be better."
"The technical support should be improved. Currently, some attacks are detected while others are not."
 

Pricing and Cost Advice

"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."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"The price is exceptionally high."
"Implementing Acunetix needs a medium or larger business agency, because you need some money to get Acunetix. It is costly, but if you care about your agency's security, then maybe it's a cost that might help you in the future."
"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."
"The solution is expensive."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"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."
"I rate the product's pricing a four out of ten."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"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 pricing is okay."
