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

"We use the solution for security testing."
"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."
"The scalability of this product is very good."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"Fuzzer and Java APIs help a lot with our custom needs."
"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."
"Automatic updates and pull request analysis."
"It can be used effectively for internal auditing."
"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."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"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 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."
"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

"It doesn't run on absolutely every operating system."
"Deployment is somewhat complicated."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"If there was an easier to understand exactly what has been checked and what has not been checked, it would make this solution better. We have to trust that it has checked all known vulnerabilities but it's a bit hard to see after the scanning."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"The forced browse has been incorporated into the program and it is resource-intensive."
"Reporting format has no output, is cluttered and very long."
"Integration could be better."
"The tech support is responsive but issues remain unresolved."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
"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 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."
"The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
"The dashboard and interface are crucial and they need some improvement."
 

Pricing and Cost Advice

"It is highly recommended as it is an open source tool."
"The tool is open-source."

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"The solution’s pricing is high."
"It is open source, and we can scan freely."
"The tool is open source."
"The price is pretty fair."
"The licensing cost depends on the number of users."

"AppSpider is closed-source software and you need to acquire a license in order to use it."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
