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.

Cons

"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."

"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"Integration could be better."
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

"The licensing cost depends on the number of users."
"The price is pretty fair."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."

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.
