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 monitoring has reduced false positives and improves dependency governance
The only area for improvement I would say is that the false positives are nearly zero; everything is mostly like 99 to 99.99% or we can say 100% accurate. There were a few areas for improvement just from the last time I saw; I think the user experience had a little problem. We wanted to have certain reports based on our kind of scenario, but the tool did not allow us to create custom reports. We had asked for some facility and some ability for us to create some custom reports. That would be awesome if they allow us to create custom reports the way we wanted. There is one small area which I don't know whether we should call a tool limitation or a wish list; if I use a library and I don't use all the capabilities of the library but only a portion of it and that portion is not vulnerable, but there is a component which is outdated, that is a problem, even though I don't use that component. Mend.io will discover there is a problem in the whole library; that is correct. That's a valid discovery, but in my case, for example, if I don't use that particular portion, then it actually is not making sense for me, but that's not a limitation of Mend.io; I think that's a general problem with any tool in the market because no tool in the market will actually know what portion of the code I'm actually using from that particular library if it is vulnerable or not.
Sathyamurthi Natarajan - PeerSpot reviewer
IT Officer (Solution Architect) at World Bank
We maintain high code standards with effective static code analysis and integration
SonarQube Server (formerly SonarQube) could be improved on the reporting front. Instead of grouping, I would prefer to scan the code as part of development and then generate a report on a daily basis among different units or projects, which is currently complicated. We need to change it to more of a portfolio report, where configuring or setting up things on the portfolio requires tagging at the ADO level.
