Where Checkmarx wins
For a large organization with formal AppSec requirements, deep language coverage, and compliance reporting obligations, Checkmarx is a serious platform. If you need governance, audit trails, and enterprise integrations across many teams, that is what it is built for.
Where Prbl is different
Checkmarx is a general SAST engine that has to be tuned and triaged. Prbl assumes an AI tool wrote the code and prioritizes the narrow set of ways that goes wrong: hardcoded secrets in scaffolding, missing authentication on generated routes, fallback secrets in environment lookups, and Broken Object Level Authorization. It returns a short, high-signal list in seconds with no setup, and it can rewrite the finding for you.
Which to choose
If you are a regulated enterprise standardizing on one AppSec platform, Checkmarx fits that shape. If you are a team shipping quickly with Cursor, Copilot, or Claude Code and you want fast, specific answers about AI-written code, Prbl is the lighter, sharper tool, and the two can run side by side.
