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

"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."
"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."
"​It has improved my organization with faster security tests.​"
"Simple and easy to learn and master."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"If you're a company and you've got your own websites, internally and externally, it's great."
"The automatic scanning is a valuable feature and very easy, and the major advantage to this solution is the privacy it offers."
"It updates repositories and libraries quickly."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"It is really accurate and the rate of false positives is very low."
"The most valuable feature is the reporting, which is compliant with international standards."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"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."
"It does a scan that performs about 100 checks on web applications and produces a clear report on all of the vulnerabilities that are found."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"The solution is highly stable, rated at ten out of ten."
 

Cons

"There isn't too much information about it online."
"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 work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"OWASP Zap needs to extend to mobile application testing."
"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."
"I would recommend this product to people although I think it is very difficult to deploy and we also have issues with maintenance."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"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."
"The dashboard and interface are crucial and they need some improvement."
"Support response times are slow and can be improved."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"The enterprise interface is too simple. It should be more customizable."
 

Pricing and Cost Advice

"OWASP Zap is free to use."
"It is open source, and we can scan freely."
"This app is completely free and open source. So there is no question about any pricing."
"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."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"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."
"The licensing cost depends on the number of users."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"The price is pretty fair."
"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."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
