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.
Frequently asked questions
Is Prbl a Checkmarx alternative for small teams?
Yes, that is specifically who it is for. Checkmarx is built for large, compliance-driven security programs with enterprise onboarding. Prbl is paste-a-repo-and-scan, tuned for teams shipping fast with AI tools who don't have a formal AppSec program yet.
Does Prbl replace Checkmarx for a regulated enterprise?
No. If you need governance, audit trails, and broad language coverage across a large org, Checkmarx is built for that. Prbl is a sharper, narrower tool for the AI-generated slice of your codebase, and the two can run side by side.
Why would a Checkmarx user also run Prbl?
Checkmarx is a general SAST engine tuned broadly; it was not built assuming an AI tool wrote the code. Prbl assumes exactly that and prioritizes the specific classes AI coding tools produce: hardcoded secrets in scaffolding, missing auth on generated routes, and BOLA.
