What Is Checkmarx One? The Enterprise SAST Platform Explained
Checkmarx One is a cloud-native application security platform that consolidates multiple scanning approaches into a single product: SAST (static analysis of source code), SCA (software composition analysis of dependencies), DAST (dynamic testing of running applications), IaC (infrastructure-as-code security), and API security testing. It is built for enterprise engineering organizations with formal security programs.
What does Checkmarx One scan?
SAST (Static Analysis): Reads your source code and identifies vulnerable patterns: SQL injection vectors, dangerous function usage, broken authentication logic, insecure data flows. Supports 30+ programming languages.
SCA (Software Composition Analysis): Checks your dependencies against CVE databases and license compliance requirements. Flags packages with known vulnerabilities and highlights problematic open-source licenses.
DAST: Tests running applications dynamically. This component is less mature than Checkmarx’s core SAST product.
IaC security: Analyzes Terraform, CloudFormation, and Kubernetes configs for misconfigurations before they reach production.
API security: Discovers and tests API endpoints for common security issues.
What does Checkmarx One cost?
Checkmarx does not publish pricing. Enterprise licenses typically start at $20,000–$50,000 per year for a team, depending on the number of developers and the modules included. It is a sales-led product available through direct sales or channel partners. There is no self-serve free tier.
Who is Checkmarx One for?
Checkmarx One is for enterprise security and engineering teams with a dedicated AppSec budget, CI/CD pipelines, and developers who will act on SAST findings at scale. It integrates into the SDLC — blocking builds on critical findings, routing findings to developer inboxes, tracking remediation over time. This is not a tool for a solo founder who needs a quick pre-launch check.
What Checkmarx One does not cover
Checkmarx One does not cover reliability, performance, or monitoring in any of its scanning modules. It does not detect which AI tool generated your code or apply AI-platform-specific rules. A Checkmarx SAST scan can come back clean on a Lovable-generated app while that app has Supabase RLS disabled, no rate limiting, and no error tracking — all the gaps that cause actual production incidents in AI-built apps.

Is Checkmarx One worth the cost for small teams?
No. Checkmarx One is priced and designed for enterprise organizations with dedicated AppSec programs. For small teams, the combination of npm audit (free), Semgrep Community (free), and Launch Ready Code ($0 free scan, $499 full audit) covers the practical gaps at a fraction of the cost.
What is the difference between Checkmarx SAST and traditional DAST?
Checkmarx SAST reads source code without running the application. DAST tools test the live, running application from the outside. SAST catches code-level vulnerabilities. DAST catches runtime behavior issues. Both are useful for different surfaces.
Does Checkmarx One detect AI-specific security issues?
Checkmarx One does not have specific detection rules for AI-builder-generated code patterns. It applies the same SAST rules regardless of whether the code was written by a human or generated by Lovable, Bolt, or Cursor.
What is a cheaper alternative to Checkmarx One for SAST?
Semgrep Community is free, covers OWASP Top 10 patterns, and is actively maintained. For a solo founder or small team, Semgrep is the practical SAST starting point.
