Effective vulnerability identification enhances security scans but AI-driven enhancements are needed
OWASP is only meant for two or three different types of scans. It is a tool which will scan the code for security for vulnerabilities We were able to convince the customers to really remove those rules when GitLab was able to show the results. Customers should be aware that GitLab is not just a…

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 most valuable feature is scanning the URL to drill down all the different sites."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"The scalability of this product is very good."
"The stability of the solution is very good."
"It's great that we can use it with Portswigger Burp."
"The ZAP scan and code crawler are valuable features."
"​It has improved my organization with faster security tests.​"
"It can be used effectively for internal auditing."
"Generating new messages, based on the existing .EDN and .XML messages, is a crucial part or the testing project that I’m currently in."
"Good write and read files which save execution inputs and outputs and can be stored locally."
"We have seen a return on investment."
"One of the most valuable features I found in Parasoft SOAtest is its ability to extend the product."
"Every imaginable source in the entire world of information technology can be accessed and used."
"If you want something that’s not provided out of the box, then you can write it yourself and integrate it with SOAtest."
"They have a feature where they can record traffic and create tests on the report traffic."
"We do a lot of web services testing and REST services testing. That is the focus of this product."
 

Cons

"There isn't too much information about it online."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"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. More reports that can have some kind of base-lining, I think that would be a good feature too. I'm not sure whether it can be achieved and implement but I think that would really help."
"I would like to see a version of “repeater” within OWASP ZAP, a tool capable of sending from one to 1000 of the same requests, but with preselected modified fields, changing from a predetermined word ​list, or manually created."
"There are too many false positives."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"Compatibility with HTTP 1.1 and TLS 1.2 needs to be improved."
"There are performance issues where the tool crashes sometimes. In particular use cases with numerous steps, it experiences crashes."
"The summary reports could be improved."
"The product is very slow to start up, and that is a bit of a problem, actually."
"UI testing should be more in-depth."
"Reporting facilities can be better."
"Tuning the tool takes time because it gives quite a long list of warnings."
"From an automation point of view, it should have better clarity and be more user friendly."
 

Pricing and Cost Advice

"It is highly recommended as it is an open source tool."
"We have used the freeware version. I believe Zap only has freeware."
"The tool is open source."

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."

"We are completed satisfied with Parasoft SOAtest. The ROI is more than 95%."
"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."
