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.

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

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

"The solution is paying for itself, as our applications are more secure."

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

"The most important element for us is that it's very easy for developers to use, as they don't need to have any knowledge about security or threats; they just run the tool against their application and get the results."

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

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

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

"The product is really easy to use."

More Acunetix pros

"The product has improved our application security engagement, helps with our in-house review so we sometimes don't need an external third-party tester, and once we get it from OWASP Zap, we have an idea of the inherent vulnerabilities in the application, which is a plus to save cost and improve our application accuracy practice."

"The best feature is the Zap HUD (Heads Up Display) because the customers can use the website normally. If we scan websites with automatic scanning, and the website has a web application firewall, it's very difficult."

"They offer free access to some other tools."

"Automatic updates and pull request analysis."

"The community support that ZAP provides me, as an open source, provides me flexibility and is convenient to use."

"If you're a company and you've got your own websites, internally and externally, it's great."

"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."

"You can run it against multiple targets."

More OWASP Zap pros

Cons

"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."

"While we do have it integrated with other solutions, it could still offer more integrations."

"One of the biggest problems I've had with Acunetix is that it's hard to replicate things manually because you don't get the raw packet."

"It is difficult to create a proxy connection."

"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."

"Tool is quite expensive though compared to other tools."

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

"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."

More Acunetix cons

"Too many false positives; test reports could be improved."

"The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format."

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

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

"The technical support team must be proactive."

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

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

"The product should allow users to customize the report based on their needs."

More OWASP Zap cons

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."

"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."

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

"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."

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

"The price is exceptionally high."

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

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

More Acunetix pricing and cost advice

"The tool is open-source."

"This is an open-source solution and can be used free of charge."

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."

"The solution’s pricing is high."

"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."

"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."

"OWASP Zap is free to use."
