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 is very easy to use, the initial setup is straightforward, it is free due to the fact that it is open-source, the stability is very good, and the product has a strong community surrounding it to help with issues and troubleshooting."
"​It has improved my organization with faster security tests.​"
"OWASP is the best."
"The interface is easy to use."
"Fuzzer and Java APIs help a lot with our custom needs."
"Technical support is excellent."
"It updates repositories and libraries quickly."
"If you're a company and you've got your own websites, internally and externally, it's great."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"This solution is a leader in the industry."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"It scans all the components developed within a web application."
"The setup is usually straightforward."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"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."
 

Cons

"It would be nice to have a solid SQL injection engine built into Zap."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"It would be beneficial to enhance the algorithm to provide better summaries of automatic scanning results."
"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."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"I would recommend this product to people although I think it is very difficult to deploy and we also have issues with maintenance."
"We have had stability issues a few times."
"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."
"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 dashboard and interface are crucial and they need some improvement."
"The enterprise interface is too simple. It should be more customizable."
"AppSpider has some problems with the RAM needed while scanning."
"The tech support is responsive but issues remain unresolved."

"OWASP Zap is free to use."
"It is open source, and we can scan freely."
"We have used the freeware version. I believe Zap only has freeware."

"The solution’s pricing is high."
"It is highly recommended as it is an open source tool."
"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."
