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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is really accurate and the rate of false positives is very low."
"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."
"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 setup is usually straightforward."
"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."
"It scans all the components developed within a web application."
"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 ability to write our custom rules."
"Compared to other competitors in the market, the AI-backed capability is the biggest strength of Semgrep."
 

Cons

"It needs better integration with mobile applications."
"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."
"This price of this solution is a little bit expensive."
"Support response times are slow and can be improved."
"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."
"There are some glitches with stability, and it is an area for improvement."
"Integration could be better."
"The enterprise interface is too simple. It should be more customizable."
"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."

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 licensing cost depends on the number of users."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"The price is pretty fair."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
