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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."
"Simple and easy to learn and master."
"You can run it against multiple targets."
"It can be used effectively for internal auditing."
"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."
"Zap is an open-source and sophisticated product that not only saves us money but also provides us with a good amount of information."
"The pull request analysis is also very good."
"It is really accurate and the rate of false positives is very low."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"The setup is usually straightforward."
"It scans all the components developed within a web application."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"What I like most about AppSpider is that it's easy to use and its automated scan gives me all the details I need to know when it comes to vulnerabilities and their solutions."
"The entire solution is interactive and has a point-and-click user experience, which makes it easy to find items or drill down on information, and you don't need specialized skills to use the product."
"This solution is a leader in the industry."
 

Cons

"The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format."
"We're currently moving away from OWASP to PortSwigger Burp Suite Professional; it's more user-friendly with a better interface."
"The documentation is lacking and out-of-date, it really needs more love."
"The reporting feature could be more descriptive."
"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."
"Reporting format has no output, is cluttered and very long."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"It doesn't run on absolutely every operating system."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"Integration could be better."
"The product needs to be able to scale for large companies, like ours. We have millions of IP addresses that need to be scanned, and the scalability is not great."
"There are some glitches with stability, and it is an area for improvement."
"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"The performance of the solution could improve. When I compare the speed it is slower than others on the market. There are some tricks we use to help speed up the solution."
 

Pricing and Cost Advice

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"The solution’s pricing is high."
"This is an open-source solution and can be used free of charge."
"The tool is open-source."
"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."
"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'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."
"This solution is open source and free."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"The price is pretty fair."
"The licensing cost depends on the number of users."
"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
