Featured Reviews

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.

Quality Specialist 2A at a financial services firm with 10,001+ employees
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

"The API is exceptional."
"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."
"The pull request analysis is also very good."
"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."
"It's great that we can use it with Portswigger Burp."
"It scans while you navigate, then you can save the requests performed and work with them later."
"If you're a company and you've got your own websites, internally and externally, it's great."
"The solution has tightened our security and that of our clients who depend on it."
"Every imaginable source in the entire world of information technology can be accessed and used."
"It provides easy handling of RESTful APIs and figuring out exact API scalability, responses, and failed APIs, returning code captured by the fault injections."
"We can automate our scenarios in a data driven format, which shows there is no rework on scripts. We only need to update the test data and run for a number of scenarios."
"As a test consultant, I have been able to deliver high quality automated testing solutions to our clients using SOAtest in a quick manner."
"Parasoft is a bundle of tools like FTP, Database, Web services, and Java, and with just one click I can access any of these utilities, which is currently saving lots of my time."
"It improved my project ROI in various portions of the testing life cycle."
"The toolset is really good, I'm really impressed with it."
"The solution is scalable."
 

Cons

"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."
"The product reporting could be improved."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"OWASP Zap needs to extend to mobile application testing."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"There's very little documentation that comes with OWASP Zap."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"The platform can become unstable as the memory usage increases."
"Yes, there were few issues, that caused the Memory out, but was resolved."
"In general, its user-friendliness needs a little improvement since there are a few bugs that still remain."
"Tuning the tool takes time because it gives quite a long list of warnings."
"Enabling/disabling an optional element of an XML request is only possible if a data source (e.g., Excel sheet) is connected to the test. Otherwise, the option is not available at all in the drop-down menu."
"I personally feel that 50% of Parasoft features are provided by SoapUI free of cost."
"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."
"Reporting facilities can be better."
