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.

Centralized security testing has improved vulnerability remediation and compliance reporting

I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

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

Pros

"The SAST component was absolutely 100% stable."

"Checkmarx offers many valuable features, including Static Application Security Testing (SAST), Software Composition Analysis (SCA), Infrastructure as Code (IAC), Supply Chain Security, and API Security."

"One of the most valuable features is it is flexible."

"It's been a very positive experience overall."

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

"The most valuable features of Checkmarx are the automation and information that it provides in the reports."

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

"Checkmarx pinpoints the vulnerability in the code and also presents the flow of malicious input across the application."

More Checkmarx One pros

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."

"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."

Cons

"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 Dynamic Application Security Testing (DAST) feature should be better."

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

"The cost per user is high and should be reduced."

"Checkmarx could improve the REST APIs by including automation."

"Scanning speed optimization is an area where improvements can be made, and we can reduce false positives."

"From an administrative standpoint, I would rate Checkmarx with a five out of ten."

"It needs better role management."

More Checkmarx One cons

"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."

Pricing and Cost Advice

"It is a good product but a little overpriced."

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

"The pricing was not very good. This is just a framework which shouldn’t cost so much."

"Checkmarx is comparatively costlier than other products, which is why some of the customers feel reluctant to go for it, though performance-wise, Checkmarx can compete with other products."

"Be cautious of the one-year subscription date. Once it expires, your price will go up."

"If you want more, you have to pay more. You have to pay for additional modules or functionalities."

"We have purchased an annual license to use this solution. The price is reasonable."

"The license has a vague language around P1 issues and the associated support. Make sure to review these in order to align them with your organizational policies."
