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.

Has reduced manual testing effort with customization options but occasionally crashes during complex executions
One improvement would be to integrate it with modern technologies such as AI, so we can generate test cases by providing the details so that it can generate the structure, and later the person working can modify and enhance it. We can add more customized tools, and reporting can be enhanced. Currently, the reporting part is at a step level, and it does not give details for a particular test case, so improvements in those areas would be beneficial. There are performance issues where the tool crashes sometimes. In particular use cases with numerous steps, it experiences crashes. I have encountered stability and performance issues with it.

Quotes from Members

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

Pros

"Zap is an open-source and sophisticated product that not only saves us money but also provides us with a good amount of information."
"Fuzzer and Java APIs help a lot with our custom needs."
"The solution is scalable."
"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."
"It scans while you navigate, then you can save the requests performed and work with them later."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"They offer free access to some other tools."
"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."
"If you want something that’s not provided out of the box, then you can write it yourself and integrate it with SOAtest."
"Web services and API test automation was made simple without writing much code."
"Customer Service: ExcellentTechnical Support: Very Good"
"Good write and read files which save execution inputs and outputs and can be stored locally."
"This tooling made us more agile and more ready for continuous integration."
"We do a lot of web services testing and REST services testing. That is the focus of this product."
"The toolset is really good, I'm really impressed with it."
"We have seen a return on investment."
 

Cons

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"The solution is somewhat unreliable because after we get the finding, we have to manually verify each of its findings to see whether it's a false positive or a true finding, and it takes time."
"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"Without any support, we are in a black hole sometimes."
"We have had stability issues a few times."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"The port scanner is a little too slow.​"
"Reporting facilities can be better."
"We have good support of our solution architect of Parasoft, but sometimes they don’t know all the answers and then it’s harder to find more knowledge in technical support from US teams, which slows things down."
"During the process of working with SOAtest and building test cases, the .TST files will grow. A negative side effect is that saving your changes takes more time."
"One area that could use improvement is the cryptography capabilities in Parasoft SOAtest. It did not support enough of the protocols or cryptography formats we needed, which led us to create our own solutions."
"The features of SOAtest used for testing (web) applications on user interface level suffice for very basic web applications, but there are better tools on the market."
"Parasoft SOAtest has an internal refresh function where you can refresh the software to show the changes you’ve made in your projects. Unfortunately this function does not work properly, because it often does not show the changes after you’ve hit te refresh button a few times."
"The user-interface is not very lightweight or friendly, sometimes buggy and cumbersome."
"The product is very slow to start up, and that is a bit of a problem, actually."
 

Pricing and Cost Advice

"We have used the freeware version. I believe Zap only has freeware."
"The tool is open-source."
"OWASP Zap is free to use."
"This is an open-source solution and can be used free of charge."
"It is highly recommended as it is an open source tool."
"This app is completely free and open source. So there is no question about any pricing."
"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 is open source, and we can scan freely."
"The price is around $5,000 USD."
"I think it would be a great step to decrease the price of the licenses."
"It is an expensive product, so think carefully about whether it fits your purposes and is the right tool for you."
"The license price is a little expensive, but it provides a better outcome in terms of the end-to-end automation process."
"From what I understand, Parasoft SOAtest isn't the cheapest option. But it has a lot to offer."
"The cost of Parasoft seems to have gotten higher with a projection that wasn't really stipulated for our company. They've done a tremendous job at negotiating those deals."
"We are completed satisfied with Parasoft SOAtest. The ROI is more than 95%."
"They do have a confusing licensing structure."
