Context-aware code analysis has reduced noise and now improves developer experience with actionable security findings
I have consistently observed that their scan time is an issue for mono repos. Sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes(, which makes it difficult. Another consistent issue is that whenever you have a new repo to onboard to the platform, the tool ideally should detect the master branch by default. However, sometimes the tool fails to identify it and will never scan it unless manually somebody looks into it and fixes the issue. Although their support team is really good, this issue was present six or eight months ago during the POC and is still present now. If it is affecting multiple customers, it should be prioritized and fixed. I would say that their integration aspects could have been improved. I see a lot of different security solutions that provide flexibility to the security teams based on Jira project, team divisions, Slack, and all those can be very much easily customized. Semgrep needs to work on the enhancement of their notification capabilities. Currently, they are working on identifying business logic vulnerabilities or privilege escalation vulnerabilities by looking at the code, and they should continue to focus on and improve this effort. Regarding stability, whenever you have a mono-repo which is a very large repository, the scan never finishes or the scan never kicks in. At that time, you have to reach out to the support team and ask them to expand the resources in the back end to fix it. This is an issue I keep seeing often on that platform.

"It does a scan that performs about 100 checks on web applications and produces a clear report on all of the vulnerabilities that are found."
"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 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."
"Customer service has been quite good."
"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, and you don't need specialized skills to use the product."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"Semgrep has positively impacted our organization by improving code quality and helping us eliminate vulnerabilities in our code."

Cons

"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"This price of this solution is a little bit expensive."
"There are some glitches with stability, and it is an area for improvement."
"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."
"It needs better integration with mobile applications."
"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."

"I have consistently observed that their scan time is an issue; sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes, which makes it difficult."
"However, as a tool it is really complex to maintain and to use, and it has a huge price tag."
 

Pricing and Cost Advice

"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."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"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."
