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

"The API is exceptional."
"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."
"The stability of the solution is very good."
"The best feature is the Zap HUD (Heads Up Display) because the customers can use the website normally. If we scan websites with automatic scanning, and the website has a web application firewall, it's very difficult."
"The solution is scalable."
"Simple and easy to learn and master."
"You can run it against multiple targets."
"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."
"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."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"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."
"It is really accurate and the rate of false positives is very low."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."
"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."
 

Cons

"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"OWASP Zap needs to extend to mobile application testing."
"OWASP should work on reducing false positives by using AI and ML algorithms."
"It needs more robust reporting tools."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"I would like to see a version of “repeater” within OWASP ZAP, a tool capable of sending from one to 1000 of the same requests, but with preselected modified fields, changing from a predetermined word ​list, or manually created."
"Deployment is somewhat complicated."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
"The performance of the solution could improve. When I compare the speed it is slower than others on the market. There are some tricks we use to help speed up the solution."
"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."
"Integration could be better."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"The product should offer a GUI in Japanese and provide Japanese reports for end-users."
 

Pricing and Cost Advice

"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."
"This app is completely free and open source. So there is no question about any pricing."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"This solution is open source and free."
"It is highly recommended as it is an open source tool."
"It is open source, and we can scan freely."
"The tool is open-source."
"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 licensing cost depends on the number of users."
"The price is pretty fair."
