Checkmarx Fusion is an additional layer in the Checkmarx scanning architecture. It runs several curated, research-validated frontier AI models on top of the hybrid engine to find vulnerabilities with no known rule, prior CVE, or signature. Findings Analysis then reconciles results into one verified set. What are the benefits of Checkmarx Fusion? Checkmarx Fusion improves detection without increasing noise. In SAST testing, F1 accuracy score increased from 0.64 to 0.74, meaning Checkmarx found more real vulnerabilities while preserving precision. Findings Analysis keeps results usable by reconciling outputs into one verified list. Is Checkmarx Fusion available? Checkmarx Fusion is being introduced as part of Checkmarx One SAST. Request a demo to confirm availability, Early Access status, and fit for your environment. What is Checkmarx Fusion, and is it available now? Checkmarx Fusion is an additional layer within Checkmarx’s scanning architecture. The hybrid engine underneath it, deterministic or AI-based depending on the language, finds known and documented vulnerabilities at the highest fidelity available today. Checkmarx Fusion runs on top of that. It runs several curated frontier AI models in parallel to catch a different class of problem entirely: vulnerabilities with no known rule, no prior CVE, and no signature to match against. The Findings Analysis Engine reconciles everything into one verified result. [Request a demo and see the highest fidelity SAST.](#form) What makes Checkmarx SAST different from traditional SAST? Most SAST tools rely on pattern matching against predefined rules. Checkmarx SAST uses a hybrid approach: deterministic, auditable analysis for core languages, an AI-powered engine for emerging and AI-generated code, and automatic classification that cuts noise by 60%. The result is 70% better fidelity than traditional SAST. Coverage, precision, and signal in the same scan. What is Findings Analysis? Findings Analysis is an AI-powered capability that evaluates scan results and classifies each finding as a likely true positive or false positive before it reaches your team. It reduces noise automatically so engineers focus on findings worth fixing. Classification is a label, not a deletion — findings are never removed, only ranked. Can't Claude or Copilot already review code for vulnerabilities? Claude suggests. Checkmarx proves. When your auditor asks whether a data flow is exploitable, your AI assistant cannot answer with certainty. We can. LLMs report high confidence even when their analysis is incomplete. That false confidence is the danger. Why do enterprise teams still need a dedicated SAST tool for AI-generated code? AI-generated code can accelerate development, but it does not guarantee secure output. Checkmarx SAST scanner validates generated and human-written code with hybrid analysis, broad language coverage, and Findings Analysis to reduce noise. What other solutions does Checkmarx have in addition to SAST? Checkmarx SAST is part of the Checkmarx One platform. This allows a complete enterprise application security program to run on a single platform, reducing total cost of ownership and allowing for correlation and better actionable insights. The Checkmarx One platform includes SAST security scanning, DAST security scanning, AI Supply Chain Security, AI BOM, SCA, SCS, API Security, IaC Security, and Container Security. How does on-premises CxSAST differ from SAST on Checkmarx One? CxSAST is on-premises and uses the traditional rules-based scanning engine. SAST on Checkmarx One includes the AI-based engine, the Findings Analysis Engine, and Checkmarx Fusion. None of which are available on-premises. If you’re running CxSAST today, moving to Checkmarx One is how you access the full hybrid scanning architecture and the F1 gains that come with it. Learn more in the [on-prem to cloud migration brief](https://checkmarx.com/resources/migrating-from-on-prem-sast-to-checkmarx-one/). What languages does Checkmarx SAST support? Checkmarx SAST supports a broad range of modern, enterprise, and legacy languages, including Java, JavaScript, TypeScript, Python, C#, C/C++, Go, PHP, Ruby, Swift, Kotlin, COBOL, PL/SQL, and more. **Don’t see your language? We’ve got you covered** [Book a call with an AppSec expert](#form) How is a SAST software scan different from a DAST scan? A SAST security scan reviews source code, looking for vulnerabilities in static code – it doesn’t require the application to be running. In contrast, a dynamic application security testing (DAST) scan evaluates a running application, testing how it behaves in real-time by simulating attacks. While SAST finds issues in the code, DAST focuses on identifying runtime vulnerabilities like authentication or input validation problems. How can Professional Services help me with my SAST solution? Professional Services help accelerate value. This starts with our Checkmarx Security Self-Assessment (APMA) framework, which provides actionable steps to improve your AppSec maturity. Professional Services also helps you optimize your solution to focus on finding exploitable vulnerabilities, as well as providing training and managed services to improve your AppSec journey. Is Checkmarx SAST a source code scanner? Yes. Checkmarx SAST scans source code directly from repositories such as GitHub, GitLab, Azure, and Bitbucket, without requiring a build. As an enterprise SAST tool, it adds security analysis, workflow integration, fix guidance, and risk context beyond basic source code scanning. ## Experience a High-Fidelity SAST Tool in Action Checkmarx SAST scans source code, finds critical vulnerabilities, and gives teams the coverage and fidelity to deliver secure applications. ### Thank You!
