Open source testing tool empowers manual activities and has room to improve integration and reporting features

The improvement that has to be done for APIs focuses on manual activities where the feature exists, but it is not at the same level as what Burp Suite does with intercepting and tools such as Postman, so it needs improvement. There are limitations with authentication levels, particularly with form-based and cookie-based authentication. However, overall, we are satisfied with OWASP Zap as there are no major issues, and improving the scan engine could be beneficial. When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking.

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.

Cons

"The automatic scans need improvement. The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."

"It needs more robust reporting tools that can be in an editable form."

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

"I'd like to see a kind of feature where we can just track what our last vulnerability was and how it has improved or not."

"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."

"While the solution can scale to a certain extent, it cannot scale a lot."

"There are too many false positives."

More OWASP Zap cons

"Reports could be customized and more descriptive according to the user's or company's requirements."

"UI testing should be more in-depth."

"The feedback that we received from the DevOps of our organization was that the tool was a little heavy from the transformation perspective."

"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."

"Compatibility with HTTP 1.1 and TLS 1.2 needs to be improved."

"The user-interface is not very lightweight or friendly, sometimes buggy and cumbersome."

"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."

"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."
