Executive SummaryUpdated on Nov 2, 2025

Acunetix and OWASP Zap compete in the web application security tools category. Acunetix seems to have the upper hand due to its automated scanning, fewer false positives, and scalability.

Features: Acunetix offers automated scanning capabilities with low false positives, a user-friendly interface, and in-depth reporting formats such as PDF and HTML. It also provides scalability through integration with various platforms, making it versatile for different environments. OWASP Zap boasts open-source accessibility with a vibrant community, customizable security testing, and flexible integration with other open-source solutions, supporting multiple platforms like Mac, Linux, and Windows.

Room for Improvement: Acunetix could improve pricing and licensing clarity and enhance manual verification and mobile app testing capabilities. Additionally, refining its false-positive rates would be beneficial. OWASP Zap should improve its reporting formats and a more robust scan engine, as well as enhance its mobile application support and vulnerability range.

Ease of Deployment and Customer Service: Acunetix offers flexible deployment options, including on-premises and cloud solutions, with 24/7 technical support, though users report some challenges with licensing clarity. OWASP Zap provides on-premises deployment and relies on community support, offering ticket-based support with reasonable response times.

Pricing and ROI: Acunetix is considered expensive, which may not suit all users but offers significant ROI through improved security. OWASP Zap is free and offers great value, with minimal financial investment required, highlighting its strong community support as a key advantage.

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.

Effective vulnerability identification enhances security scans but AI-driven enhancements are needed

Quotes from Members

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

Pros

"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."

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

"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."

"We use the solution for the scanning of vulnerabilities like SQL injections."

"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."

"Picks up weaknesses in our app setups."

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

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

More Acunetix pros

"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."

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

"The solution is scalable."

"We use the solution for security testing."

"Simple to use, good user interface."

"The application scanning feature is the most valuable feature."

"The product helps users to scan and fix vulnerabilities in the pipeline."

"The ZAP scan and code crawler are valuable features."

More OWASP Zap pros

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 solution's pricing could be better."

"I think Acunetix needs improvement since it is now working with Invicti, so the price list will need to be reconsidered."

"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."

"Acunetix should improve by further reducing false positives and providing more customized reports, plus better integration with newer tools such as GitHub and Azure DevOps."

"There's a clear need for a reduction in pricing to make the service more accessible."

"The pricing is a bit on the higher side."

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

More Acunetix cons

"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."

"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."

"The reporting feature could be more descriptive."

"There are too many false positives."

"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."

"The documentation needs to be improved because I had to learn everything from watching YouTube videos."

"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."

"Deployment is somewhat complicated."

Pricing and Cost Advice

"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."

"The pricing is a little high, and moreover, it's kind of domain-based."

"The solution is expensive."

"The price is exceptionally high."

"The costs aren't very expensive. It costs around $3000 or $4000."

"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 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."

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

More Acunetix pricing and cost advice

"This app is completely free and open source. So there is no question about any pricing."

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

"This solution is open source and free."

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

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

"OWASP Zap is free to use."

"The solution’s pricing is high."

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