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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

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

Pros

"The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution."

"The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications, so that really makes it a very, very versatile solution to have."

"The most valuable feature of Acunetix is the UI and the scan results are simple."

"There is a lot of documentation on their website which makes setting it up and using it quite simple."

"By integrating with CI/CD tools, it enables a shift-left approach in the development process."

"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."

"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."

"I haven't seen reporting of that level in any other tool."

More Acunetix pros

"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."

Cons

"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."

"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."

"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."

"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 time to fix issues is not too quick, so in the case of time-restricted projects for some customers, this might become a problem."

"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."

"However, it doesn't seem very helpful or useful for scanning web services, and that has what I feel that the organization could work better on that."

"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."

More Acunetix cons

"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."

Pricing and Cost Advice

"The solution is expensive."

"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."

"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."

"All things considered, I think it has a good price/value ratio."

"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."

"Acunetix was around the same price as all the other vendors we looked at, nothing special."
