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.

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

"OWASP is definitely in the top three as a tool that we would probably recommend to our team, as a frequent users' tool, however, I don't believe we have any kind of a formal relationship with the company."
"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."
"The product discovers more vulnerabilities compared to other tools."
"The solution enables a person to add the certificate and check the queries, to see if there are any that are undefined, so a person can have a list of the types of queries and can trace them."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"Fuzzer and Java APIs help a lot with our custom needs."
"OWASP is the best."
"Automatic testing is the most valuable feature."
"Web services and API test automation was made simple without writing much code."
"Every imaginable source in the entire world of information technology can be accessed and used."
"Customer Service: ExcellentTechnical Support: Very Good"
"Generating new messages, based on the existing .EDN and .XML messages, is a crucial part or the testing project that I’m currently in."
"We don’t have to manually create .EDN and .XML messages, because we can do this with just one click now, which drastically decreases the time that is required to create these messages."
"One of the most valuable features I found in Parasoft SOAtest is its ability to extend the product."
"Since the solution has both command line and automation options, it generates good reports."
 

Cons

"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"There are too many false positives."
"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."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."
"It doesn't run on absolutely every operating system."
"The product reporting could be improved."
"I was having trouble with the browser automation on my Mac laptop."
"There are performance issues where the tool crashes sometimes. In particular use cases with numerous steps, it experiences crashes."
"Yes, there were few issues, that caused the Memory out, but was resolved."
"I personally feel that 50% of Parasoft features are provided by SoapUI free of cost."
"The platform can become unstable as the memory usage increases."
"Reporting facilities can be better."
"Compatibility with HTTP 1.1 and TLS 1.2 needs to be improved."
"The need to refresh 'Test Case Explorer' when adding a data source or environment file, can be improved."
 

Pricing and Cost Advice

"It is open source, and we can scan freely."
"The tool is open source."
"This app is completely free and open source. So there is no question about any pricing."
"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 highly recommended as it is an open source tool."
"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."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"This is an open-source solution and can be used free of charge."
"From what I understand, Parasoft SOAtest isn't the cheapest option. But it has a lot to offer."
"The price is around $5,000 USD."
"It is an expensive product, so think carefully about whether it fits your purposes and is the right tool for you."
"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%."
"The license price is a little expensive, but it provides a better outcome in terms of the end-to-end automation process."
"I think it would be a great step to decrease the price of the licenses."
"They do have a confusing licensing structure."
