Checkmarx One alternatives
13 other tools do this job. Which one is right depends on why Checkmarx One is not working for you — so start from the reason, not the list.
Why teams leave Checkmarx One
- Expensive, with a long procurement and deployment cycle.
- High false-positive volume typical of deep SAST; tuning is a project.
- Scans are slow relative to developer-first tools.
Worth saying: Checkmarx One is genuinely strong at this — very deep sast analysis with wide language coverage including legacy enterprise languages. If that is the part you rely on, switching may cost more than it saves.
If cost is the problem
Cheaper than Checkmarx One at the entry point, or free outright.
