Executive SummaryUpdated on Jul 27, 2025

Acunetix and OWASP Zap compete in the web application security testing category. Acunetix appears to have the upper hand due to its advanced reporting and scanning features.

Features: Acunetix offers a web-based interface, the Interactive Application Security Testing (IAS) module, and comprehensive scheduling and reporting features. OWASP Zap, being open-source and free, supports automation and integration capabilities but lacks in-depth reporting.

Room for Improvement: Acunetix could enhance its IAS module, simplify manual replication of findings, and improve user interface intuitiveness. OWASP Zap would benefit from better documentation and reporting features, reduced false positives, and improved scanning speed and coverage.

Ease of Deployment and Customer Service: Acunetix supports versatile deployment methods, both on-premises and hybrid cloud. Customer support is mixed with occasional delays. OWASP Zap mainly supports on-premises deployment with community support and a ticketing system for customer service.

Pricing and ROI: Acunetix is a premium tool with increased pricing over time, but users report positive ROI due to its comprehensive features. OWASP Zap offers great value as a free, open-source tool suitable for smaller businesses but requires more manual effort for equivalent security assurance.

CEO at Xcelliti

Has enabled teams to improve security testing with smooth integration and high accuracy

Acunetix has a very good ratio of fewer false positives, so users don't need to retest everything. Acunetix operates smoothly with no interruptions required, and it performs at 100% efficiency without issues in scanning anything. The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities. Acunetix integrates with every type of tool, including CI/CD tools, offering 100% integration in DevOps environments. The main benefit of Acunetix is that at the first level, users can address security issues related to penetration testing, allowing them to expose vulnerabilities and ensure all required testing is completed with very few false positives.

Amit Beniwal

Project Manager at Al Hassan LLC

Simplifies vulnerability discovery and has high quality support

There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Quotes from Members

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

Pros

"For us, the most valuable aspect of the solution is the log-sequence feature."

"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."

"The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities."

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

"I find it to be one of the most comprehensive tools, with support for manual intervention."

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

"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."

More Acunetix pros

"It can be used effectively for internal auditing."

"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."

"Simple to use, good user interface."

"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."

"We use the solution for security testing."

"The product discovers more vulnerabilities compared to other tools."

"They offer free access to some other tools."

"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."

More OWASP Zap pros

Cons

"It is difficult to create a proxy connection."

"I rate its stability six out of ten."

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

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

"Acunetix needs to be dynamic with JavaScript code, unlike Netsparker which can scan complex agents."

"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."

"Currently only supports web scanning."

"There is room for improvement in the pricing."

More Acunetix cons

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."

"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."

"When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking."

"For scalability, I would rate OWASP Zap between four to five out of ten."

"The forced browse has been incorporated into the program and it is resource-intensive."

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

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

"The product reporting could be improved."

More OWASP Zap cons

Pricing and Cost Advice

"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."

"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."

"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 solution is expensive."

"The price is exceptionally high."

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

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

More Acunetix pricing and cost advice

"The tool is open source."

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

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

"It's free. It's good for us because we don't know what the extent of our use will be yet. It's good to start with something free and easy to use."

"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."

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

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