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 vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"The stability of the solution is very good."
"We use OWASP Zap for web application security scanning."
"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."
"Technical support is excellent."
"One valuable feature of OWASP Zap is that it is simple to use."
"The application scanning feature is the most valuable feature."
"Fuzzer and Java APIs help a lot with our custom needs."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"Customer service has been quite good."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"It scans all the components developed within a web application."
"The most valuable feature is the reporting, which is compliant with international standards."
"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."
"I would say that it is stable, as I am not aware of any major issues."
 

Cons

"The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format."
"There's very little documentation that comes with OWASP Zap."
"There isn't too much information about it online."
"Deployment is somewhat complicated."
"I'd also like to see an improvement in test reports because we get too many false positives."
"We get too many false positives and that should definitely be improved."
"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."
"The technical support team must be proactive."
"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
"The tech support is responsive but issues remain unresolved."
"The dashboard and interface are crucial and they need some improvement."
"The enterprise interface is too simple. It should be more customizable."
"Support response times are slow and can be improved."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
 

Pricing and Cost Advice

"This solution is open source and free."
"It is open source, and we can scan freely."
"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."

"The tool is open source."
"This is an open-source solution and can be used free of charge."

"The price is pretty fair."
"The licensing cost depends on the number of users."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
