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

"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."
"The valuable features are that it's very simple to use and the user interface is very good, particularly for beginners so they can start the application easily."
"We use OWASP Zap for web application security scanning."
"OWASP is the best."
"This is a very mature tool; it is capable of facilitating the work of many security experts, and I highly recommend it for beginners and advanced users when some other tools fail to catch traffic."
"Fuzzer and Java APIs help a lot with our custom needs."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"The stability of the solution is very good."
"Automatic testing is the most valuable feature."
"In general, this is a hassle free, user friendly tool and it doesn't require much knowledge if you're using the manual testing."
"Web services and API test automation was made simple without writing much code."
"The solution is scalable."
"This is the best tool for API and back-end automation."
"Since the solution has both command line and automation options, it generates good reports."
"This tooling made us more agile and more ready for continuous integration."
"The best feature of Parasoft SOAtest is the extension tool where we can write our custom scripts, integrate with different languages, and customize as per our needs, which helps in a very positive way where things are not available beforehand; we can test with service virtualization."
 

Cons

"It would be nice to have a solid SQL injection engine built into Zap."
"The documentation is lacking and out-of-date, it really needs more love."
"Without any support, we are in a black hole sometimes."
"The product should allow users to customize the report based on their needs."
"The forced browse has been incorporated into the program and it is resource-intensive."
"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."
"The computers perform somewhat slowly when loading a large number of queries into memory."
"More descriptive reports are needed."
"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."
"The summary reports could be improved."
"Compatibility with HTTP 1.1 and TLS 1.2 needs to be improved."
"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."
"Work file [tst] gradually increases in size due to saving or updates of workspace. I can see a major improvement in that."
"Tuning the tool takes time because it gives quite a long list of warnings."
 

Pricing and Cost Advice

"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"We have used the freeware version. I believe Zap only has freeware."
"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."

"OWASP Zap is free to use."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"This solution is open source and free."
"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."
"We are completed satisfied with Parasoft SOAtest. The ROI is more than 95%."
"It is an expensive product, so think carefully about whether it fits your purposes and is the right tool for you."
"The price is around $5,000 USD."
"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."
"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."
"I think it would be a great step to decrease the price of the licenses."
"They do have a confusing licensing structure."
