This solution is focused on IaC. If you need full application SAST alongside IaC scanning, you need the broader Checkmarx One platform. The Visual Studio and Azure DevOps integrations are solid for Microsoft-centric shops, but teams running on other IDEs or CI systems should verify integration support before committing. It is also worth noting that IaC scanning is increasingly a feature bundled into broader CNAPP and CSPM platforms, so evaluate whether a dedicated IaC scanner or a platform with IaC scanning built in better fits your existing stack.
