Checkmarx API Security review
A strong API inventory and discovery layer, but not a complete runtime protection platform.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Checkmarx API Security is an API security capability integrated with the Checkmarx One application security platform. It is designed for application-security teams and developers in enterprise organizations that need visibility into APIs across the software development lifecycle. The product discovers endpoints from source code and documentation, builds a global API inventory, identifies shadow and zombie APIs, detects sensitive-data parameters, and prioritizes risk by business impact. Its web and API access support a cloud deployment model.
The strongest fit is for teams that want API discovery tied to existing development and application-security workflows. Checkmarx API Security scans OpenAPI, Swagger, and Postman collections, compares API implementations with their documentation, and tracks API changes and lifecycle history. It also correlates SAST findings with DAST runtime-testing results, helping teams connect code-level issues with application behavior. Integrations include GitHub, GitLab, Bitbucket, Azure DevOps, Jira, GitHub Issues, Azure Boards, Slack, Microsoft Teams, email, CI/CD platforms, and IDE plugins. These connections make it practical for teams already coordinating remediation through development tools and collaboration channels.
According to the published plan information, Checkmarx One bundle pricing is based on developers, apps, and usage, with a custom quote. There is no free plan. That structure is more suitable for organizations evaluating API security as part of a broader application-security platform than for small teams seeking a self-serve API tool. The main boundary is coverage: API inventory, documentation governance, sensitive-data detection, and SAST/DAST correlation are well represented, while verified runtime protection is not. Choose it for source-based API visibility and lifecycle assessment; choose an alternative if active runtime defense is a central requirement.
Checkmarx API Security pros and cons

- Correlates SAST and DAST findings for risk prioritization
- Where it doesn't
- Does not provide verified runtime protection
- Pricing requires a custom quote
- Best suited to Checkmarx One environments
