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 solution improved the efficiency of our code security reviews. It helps tremendously because it finds hundreds of potential problems sometimes."

"The SAST component was absolutely 100% stable."

"The reports are very good because they include details on the code level, and make suggestions about how to fix the problems."

"Overall, the ability to find vulnerabilities in the code is better than the tool that we were using before."

"The user interface is excellent. It's very user friendly."

"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."

"Most valuable features include: ease of use, dashboard. interface and the ability to report."

"The features and technologies are very good. The flexibility and the roadmap have also been very good. They're at the forefront of delivering the additional capabilities that are required with cloud delivery, etc. Their ability to deliver what customers require and when they require is very important."

More Checkmarx One pros

"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."

"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."

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

"It scans all the components developed within a web application."

"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."

"When it is set up properly, it can do scanning on web apps with multiple engines automatically."

"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."

More Rapid7 AppSpider pros

Cons

"The integration could improve by including, for example, DevSecOps."

"Checkmarx One is often down when the cloud provider experiences issues. A more fail-tolerant solution needs to be created."

"Checkmarx could improve the speed of the scans."

"One area for improvement in Checkmarx is pricing, as it's more expensive than other products."

"They can support the remaining languages that are currently not supported. They can also create a different model that can identify zero-day attacks. They can work on different patterns to identify and detect zero-day vulnerability attacks."

"Checkmarx could be improved with more integration with third-party software."

"Creating and editing custom rules in Checkmarx is difficult because the license for the editor comes at an additional cost, and there is a steep learning curve."

"Checkmarx One can be improved on the side of faster scans, especially when our CI pipelines are scanning for vulnerabilities."

More Checkmarx One cons

"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."

"Integration could be better."

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

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

"Support response times are slow and can be improved."

"The product should offer a GUI in Japanese and provide Japanese reports for end-users."

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

"The dashboard and interface are crucial and they need some improvement."

More Rapid7 AppSpider cons

Pricing and Cost Advice

"The pricing is competitive and provides a lower TCO (total cost of ownership) for achieving application security."

"I would rate the solution’s pricing an eight out of ten. The tool’s pricing is higher than others and it is for the license alone."

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

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

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

"The interface used to create custom rules comes at an additional cost."

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

"Before implementing the product I would evaluate if it is really necessary to scan so many different languages and frameworks. If not, I think there must be a cheaper solution for scanning Java-only applications (which are 90% of our applications)."

More Checkmarx One pricing and cost advice

"The licensing cost depends on the number of users."

"The price is pretty fair."

"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."

"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."
