Rizwan-Alam - PeerSpot reviewer
Easy automated web app scanning, but gives many false positives and isn't always stable
One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions. This is the main aspect that I hope to see Rapid7 improve on. Beyond reducing false positives, I would also like to see them implement better reporting features, particularly in the executive summary type of reports which need to be user-friendly and easily understood by non-technical people. The recommendations and solutions on these reports could always be improved to make them more relevant, too. Lastly, the stability isn't that great, and sometimes it becomes non-responsive. I feel like the stability of the application is very average and currently needs more work.

Pros

"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"I would say that it is stable, as I am not aware of any major issues."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"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."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"The most valuable feature is the reporting, which is compliant with international standards."
"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."

More Rapid7 AppSpider pros
"The most valuable features of Synopsys API Security Testing are the metrics, results, and threat vectors that it shares."
 

Cons

"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 tech support is responsive but issues remain unresolved."
"The dashboard and interface are crucial and they need some improvement."
"Support response times are slow and can be improved."

"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"The enterprise interface is too simple. It should be more customizable."
"This price of this solution is a little bit expensive."
More Rapid7 AppSpider cons
"The solution required us to use our team and we spoke to Synopsys API Security Testing's support to do the implementation. We use two people from our team for the implementation. and one person for maintenance."
 

Pricing and Cost Advice

"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."
"The price is pretty fair."
"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."

Overview

SPAs, APIs, mobile—the evolution of application technology is measured in months, not years. Is your web application security testing tool designed to keep up? AppSpider lets you collect all the information needed to test all the apps so that you aren’t left with gaping application risks.

Our dynamic application security testing (DAST) solution crawls to the deepest, darkest corners of even the most modern and complex apps to effectively test for risk and get you the insight you need to remediate faster. With AppSpider on your side (or, rather, all of your sides), you’ll be able to scan all the apps today and always be ready for whatever comes next.

Rapid7

AppSec testing optimized for the needs of API developers
APIs provide open, flexible interfaces that enable applications and services to talk to each other. But these characteristics can also make it difficult to build secure software—and even more difficult for traditional AppSec tools to test it.
