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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

Web audits have identified vulnerabilities and now provide clear visibility into compliance gaps
We have experience with Tenable.io Web Application Scanning, and we use it as well; we have approximately ten licenses for web application scanning. We use it to find vulnerabilities, but Tenable.io Web Application Scanning does not include remediation; we remediate with other products. We use the…

Quotes from Members

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

Pros

"The product is really easy to use."
"Overall, it's a very good tool and a very good engine."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"By integrating with CI/CD tools, it enables a shift-left approach in the development process."
"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."
"The solution is paying for itself, as our applications are more secure."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"Our primary use case for the solution is automated scanning; it doesn't require scripting knowledge or any of those suites or other tools, so it is fully automated, and we provide the credentials and URL and the tool does all scanning and will show the result per the requirement."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"The initial setup is straightforward."
"If customers need a cost-efficient way to do very good ramification scanning and vulnerability management, this is the right solution."
"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud. Tenable has its own cloud where Tenable.io is running, but there are many connectors to other cloud solutions. Tenable can do vulnerability scanning for other cloud managers such as Azure, Amazon, and so on."
"Tenable.io Web Application Scanning is very easy to use."
"I would recommend Tenable.io Web Application Scanning to others."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
 

Cons

"The Acunetix licensing and pricing model is somewhat complicated. If we calculated all of our domains and sub-domains, the sum would be huge; that's why we thought of leaving Acunetix."
"The solution can be improved by adding the ability to scan subdomains automatically, and by providing reports that can be exported to external databases to share with other solutions."
"Tool is quite expensive though compared to other tools."
"Improving the handling of false positives would be beneficial because it can be challenging to trust the findings flagged by Acunetix, and those findings must be manually validated."
"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."
"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."
"However, their response is too slow."
"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."
"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."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"The dashboard could be more user-friendly."
"It would be great if there were a dashboard that is more user-friendly."
"The platform's technical support services could be better."
"The dashboard could be more user-friendly."
 

Pricing and Cost Advice

"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."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"The price is exceptionally high."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"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 pricing is a little high, and moreover, it's kind of domain-based."
"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."
"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 pricing is okay."
"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."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"I rate the product's pricing a four out of ten."
"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."
