Executive SummaryUpdated on Feb 8, 2026

Acunetix and OWASP Zap are contenders in web application security testing. Acunetix generally leads due to its extensive feature set, though OWASP Zap’s cost-effectiveness as a free tool makes it more accessible for smaller organizations.

Features: Acunetix offers scheduling of tests, an Interactive Application Security Testing module, and comprehensive reporting. It also integrates with other applications, providing flexibility and scalability. OWASP Zap provides automated scanning, API support, and a user-friendly interface beneficial for beginners and supports various platforms like Mac, Linux, and Windows.

Room for Improvement: Acunetix users mention the need for better report customization and have noted issues with false positives. More integration capabilities with newer tools like GitHub and flexible licensing options are also desired. For OWASP Zap, improvements in reporting with more graphical illustrations, enhanced tackling of false positives, and advanced features for mobile app testing are suggested. Users also seek more frequent updates and increased coverage complexity.

Ease of Deployment and Customer Service: Acunetix supports versatile deployment options, including on-premises and hybrid cloud, and offers satisfactory technical support, although improvement in response times is noted. OWASP Zap, primarily deployed on-premises, benefits from community-driven support, providing timely assistance despite the lack of traditional 24-hour customer service.

Pricing and ROI: Acunetix is perceived as expensive, with rising costs impacting its value compared to alternatives but offers a return on investment through enhanced security. Conversely, OWASP Zap, being free and open-source, eliminates licensing costs, significantly boosting ROI, particularly for organizations with limited budgets.

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.

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."

"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."

"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."

"Picks up weaknesses in our app setups."

"The features of Acunetix have proved most effective in identifying vulnerabilities."

"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."

More Acunetix pros

"Simple to use, good user interface."

"The interface is easy to use."

"The solution is scalable."

"The most valuable feature is scanning the URL to drill down all the different sites."

"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."

"OWASP is quite matured in identifying the vulnerabilities."

"The stability of the solution is very good."

"It can be used effectively for internal auditing."

More OWASP Zap pros

Cons

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

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

"Currently only supports web scanning."

"I rate its stability six out of ten."

"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."

"Acunetix may need to reconsider the cost or price compared to other vendors."

"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 pricing is a bit on the higher side."

More Acunetix cons

"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."

"It would be nice to have a solid SQL injection engine built into Zap."

"The reporting feature could be more descriptive."

"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."

"The product reporting could be improved."

"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."

"It would be a great improvement if they could include a marketplace to add extra features to the tool."

"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."

More OWASP Zap cons

Pricing and Cost Advice

"The solution is expensive."

"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."

"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."

"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."

"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."

"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."

More Acunetix pricing and cost advice

"It is open source, and we can scan freely."

"It is highly recommended as it is an open source tool."

"We have used the freeware version. I believe Zap only has freeware."

"The tool is open-source."

"The solution’s pricing is high."

"This solution is open source and free."

"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."

"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
