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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Automatic updates and pull request analysis."
"The application scanning feature is the most valuable feature."
"OWASP is quite matured in identifying the vulnerabilities."
"Fuzzer and Java APIs help a lot with our custom needs."
"The solution has tightened our security."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."
"You can run it against multiple targets."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"It scans all the components developed within a web application."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"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 most valuable feature is the reporting, which is compliant with international standards."
 

Cons

"The forced browse has been incorporated into the program and it is resource-intensive."
"The port scanner is a little too slow.​"
"Sometimes, we get some false positives."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"Deployment is somewhat complicated."
"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."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"The enterprise interface is too simple. It should be more customizable."
"AppSpider has some problems with the RAM needed while scanning."
"There are some glitches with stability, and it is an area for improvement."

"It needs better integration with mobile applications."
"This price of this solution is a little bit expensive."
