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 HUD, Heads Up Display, is a good feature; it provides on-site testing and saves a lot of time."
"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 community support that ZAP provides me, as an open source, provides me flexibility and is convenient to use."
"If you're a company and you've got your own websites, internally and externally, it's great."
"The application scanning feature is the most valuable feature."
"The automatic scanning is a valuable feature and very easy, and the major advantage to this solution is the privacy it offers."
"They offer free access to some other tools."
"The product discovers more vulnerabilities compared to other tools."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"I would say that it is stable, as I am not aware of any major issues."
"The most valuable feature of Rapid7 AppSpider is the vulnerability reporting data. Additionally, the data is reported in a convenient way rather than seeing them as a PDF. We are able to generate all the reports exactly what we want in a flexible way."
"Customer service has been quite good."
"It is really accurate and the rate of false positives is very low."
"The setup is usually straightforward."
"The solution is highly stable, rated at ten out of ten."
"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."
 

Cons

"Lacks resources where users can internally access a learning module from the tool."
"While the solution can scale to a certain extent, it cannot scale a lot."
"There isn't too much information about it online."
"We get too many false positives and that should definitely be improved."
"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."
"The forced browse has been incorporated into the program and it is resource-intensive."
"The reporting feature could be more descriptive."
"The computers perform somewhat slowly when loading a large number of queries into memory."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
"The enterprise interface is too simple. It should be more customizable."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
"The tech support is responsive but issues remain unresolved."
"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."
"It needs better integration with mobile applications."
"There are some glitches with stability, and it is an area for improvement."
 

Pricing and Cost Advice

"The tool is open source."

"OWASP Zap is free to use."
"The tool is open-source."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"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."
"The price is pretty fair."
"The licensing cost depends on the number of users."
