Enable secure development workflows while identifying opportunities for faster scans and improved AI guidance

Checkmarx One is a very strong platform, but there are several areas where it can improve to support modern DevSecOps workflows even better. For example, better real-time developer guidance is needed. The IDE plugin should offer richer AI-powered auto-fixes similar to SNYK Code or GitHub Copilot Security, as current guidance is good but not deeply contextual for large-scale enterprise codebases. This matters because it reduces developer friction and accelerates shift-left adoption. More transparency control over the correlation engines is another need. The correlation engine is powerful but not fully transparent. Users want to understand why vulnerabilities were correlated or de-prioritized, which helps AppSec teams trust the prioritization logic. Faster SAST scan and more language coverage is needed since SAST scan can still be slow for very large mono-repos and there is limited deep support for new language frameworks like Rust and Go, along with advanced coverage for serverless-specific frameworks. This matters because large organizations want sub-minute scans in CI/CD as cloud-native ecosystems evolve fast. A strong API security module is another area for enhancement. API security scanning could be improved with active testing, API discovery, full Swagger, OpenAPI, drift detection, and schema-based fuzzing. This is important as API attacks are one of the biggest AppSec risks in 2025. Checkmarx One is strong, but I see a few areas for improvement including faster SAST scanning for large mono-repos, deeper language framework support, more transparent correlation logic, and stronger API security that includes discovery and runtime context. The IDE plugin could offer more AI-assisted fixes, and the SBOM lifecycle tracking can evolve further. Enhancing integration with SIEM and SOAR would also make enterprise adoption smoother, and these improvements would help developers and AppSec teams move faster with more accuracy.

Quotes from Members

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

Pros

"The most valuable features of Checkmarx are difficult to pinpoint because of the way the functionalities and the features are intertwined, it's difficult to say which part of them I prefer most. You initiate the scan, you have a scan, you have the review set, and reporting, they all work together as one whole process. It's not like accounting software, where you have the different features, et cetera."

"The most valuable feature is the simple user interface."

"Our static operation security has been able to identify more security issues since implementing this solution."

"The most valuable feature for me is the Jenkins Plugin."

"The process of remediating software security vulnerabilities can now be performed (ongoing) as portions of the application are being built in advance of being compiled."

"Overall, I use Checkmarx One as a strategic control point to improve developer velocity while strengthening application security across the full software lifecycle."

"Checkmarx One has definitely helped us to save time and reduce the need for additional security resources, meaning employees."

"It has all the features we need."

More Checkmarx One pros

"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 most valuable feature is the reporting, which is compliant with international standards."

"The solution is highly stable, rated at ten out of ten."

"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."

"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."

"It is really accurate and the rate of false positives is very low."

"The setup is usually straightforward."

More Rapid7 AppSpider pros

Cons

"There is nothing particular that I don't like in this solution. It can have more integrations, but the integrations that we would like are in the roadmap anyway, and they just need to deliver the roadmap. What I like about the roadmap is that it is going where it needs to go. If I were to look at the roadmap, there is nothing that is jumping out there that says to me, "Yeah. I'd like something else on the roadmap." What they're looking to deliver is what I would expect and forecast them to deliver."

"The plugins for the development environment have room for improvements such as for Android Studio and X code."

"I really would like to integrate it as a service along with the SAP HANA Cloud Platform. It will then be easy to use it directly as a service."

"We would like to be able to run scans from our local system, rather than having to always connect to the product server, which is a longer process."

"Licensing models and Swift language support are the aspects in which this product needs to improve. Swift is a new language, in which major customers require support for lower prices."

"Some of the descriptions were found to be missing or were not as elaborate as compared to other descriptions. Although, they could be found across various standard sources but it would save a lot of time for developers, if this was fixed."

"The validation process needs to be sped up."

"For Checkmarx One, I think that adding repositories and scanning impromptu code could improve it."

More Checkmarx One cons

"The enterprise interface is too simple. It should be more customizable."

"AppSpider has some problems with the RAM needed while scanning."

"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 price of this solution is a little bit expensive."

"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."

"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."

"The tech support is responsive but issues remain unresolved."

More Rapid7 AppSpider cons

Pricing and Cost Advice

"I believe pricing is better compared to other commercial tools."

"This solution is expensive. The customized package allows you to buy additional users at any time."

"We have a subscription license that is on a yearly basis, and it's a pretty competitive solution."

"For around 250 users or committers, the cost is approximately $500,000."

"We're using a commercial version of Checkmarx, and we paid for the solution for one year. The price is high and could be reduced."

"Checkmarx is not a cheap scanning tool, but none of the security tools are cheap. Checkmarx is a powerful scanning tool, and it’s essential to have one of these products."

"The price of Checkmarx could be reduced to match their competitors, it is expensive."

"The solution's price is high and you pay based on the number of users."

More Checkmarx One pricing and cost advice

"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."

"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."
