Featured Reviews

Amit Beniwal - PeerSpot reviewer
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.
Andrei Bigdan - PeerSpot reviewer
Useful vulnerability reporting data, flexible, and simple implementation
I have had some stability problems but it could be the Microsoft Windows operating system. I found that closing other applications helps with stability. It is helpful to have as much memory as possible, such as eight gigabytes. The more pages being processed the more resources you need. I rate the stability of Rapid7 AppSpider a nine out of ten.

Pros

"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."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"It updates repositories and libraries quickly."
"The most valuable feature is scanning the URL to drill down all the different sites."
"The solution is good at reporting the vulnerabilities of the application."
"Simple to use, good user interface."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"It is really accurate and the rate of false positives is very low."
"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. You don't need specialized skills to use the product."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"I would say that it is stable, as I am not aware of any major issues."
"The most valuable feature is the reporting, which is compliant with international standards."
"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."

Cons

"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"Deployment is somewhat complicated."
"It would be beneficial to enhance the algorithm to provide better summaries of automatic scanning results."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"Reporting format has no output, is cluttered and very long."
"The port scanner is a little too slow.​"
"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."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"The tech support is responsive but issues remain unresolved."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"AppSpider has some problems with the RAM needed while scanning."
"The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"This price of this solution is a little bit expensive."
