Executive SummaryUpdated on Apr 20, 2025

Acunetix and OWASP ZAP compete in the web application security testing category. Acunetix appears to have an edge due to its advanced features and user-friendly interface.

Features: Acunetix offers advanced features such as the Interactive Application Security Testing (IAST) module, robust scan scheduling capabilities, and detailed reporting. It provides ease of parameterizing attacks and generating PCI DSS compliance reports. OWASP ZAP provides open-source accessibility, making it cost-effective for users. It offers automated scanning, spidering, and comprehensive testing for vulnerabilities. Its strong community-driven development ensures continuous updates and enhancements.

Room for Improvement: Acunetix could improve its pricing model and manage license complexity, while enhancing interactive security testing and reducing false positives. OWASP ZAP needs better documentation, integration with more threat intelligence sources, and enhancements in reporting and vulnerability coverage. Users of both tools seek lower false positives.

Ease of Deployment and Customer Service: Acunetix and OWASP ZAP can be deployed on-premises, with Acunetix also available as a hybrid cloud option. Acunetix provides 24/7 support, although some users experience delayed responses. OWASP ZAP relies largely on community support due to its open-source nature, with official support often being ticket-based.

Pricing and ROI: Acunetix follows a high pricing model, with recent increases causing user concern despite a good ROI in security improvement. OWASP ZAP is free, eliminating financial barriers and making it popular among cost-sensitive users although its direct financial ROI is less evident.

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.

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 generates automated reports."

"The product is really easy to use."

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

"The tool's most valuable feature is performance."

"Picks up weaknesses in our app setups."

"The scalability is good. 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."

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

"The most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great."

More Acunetix pros

"We use the solution for security testing."

"You can run it against multiple targets."

"It updates repositories and libraries quickly."

"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."

"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."

"OWASP is quite matured in identifying the vulnerabilities."

"The solution is good at reporting the vulnerabilities of the application."

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

More OWASP Zap pros

Cons

"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."

"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."

"Currently only supports web scanning."

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

"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."

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

"There is room for improvement in the pricing."

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

More Acunetix cons

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

"The documentation is lacking and out-of-date, it really needs more love."

"The port scanner is a little too slow."

"Deployment is somewhat complicated."

"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."

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

"OWASP should work on reducing false positives by using AI and ML algorithms. They should expand their capabilities for broader coverage of business logic flaws and complex issues."

"OWASP should work on reducing false positives by using AI and ML algorithms."

Pricing and Cost Advice

"The solution is expensive."

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

"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."

"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."

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

"The price is exceptionally high."

"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."

"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

"The tool is open source."

"The tool is open-source."

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

"OWASP Zap is free to use."

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

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

"The solution’s pricing is high."

"This solution is open source and free."
