Checkmarx API Security is a commercial api security tool by Checkmarx. Data Theorem API Security is a commercial api security tool by Data Theorem. Compare features, ratings, integrations, and community reviews side by side to find the best api security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams managing sprawling microservices architectures need Checkmarx API Security because it finds APIs buried in code and documentation that other tools skip entirely, then maps business risk onto each vulnerability instead of treating them equally. The tool discovers shadow and zombie APIs while integrating DAST findings into one inventory, covering NIST ID.AM and ID.RA functions that most API scanners leave incomplete. Skip this if your organization has fewer than a dozen APIs or runs a monolithic stack; the discovery and inventory overhead pays off only when you've lost visibility into your own endpoints.
Mid-market and enterprise teams managing APIs across multiple cloud platforms should choose Data Theorem API Security for its agentless discovery that actually finds shadow APIs without requiring agents deployed to every service. The platform covers the full NIST ID and PR functions,asset inventory, risk assessment, and runtime protection,which means you get both what's running and continuous monitoring of what it's doing, not just point-in-time scanning. Skip this if your APIs are mostly on-premise and behind mature WAF stacks; the value proposition is strongest when you're chasing undocumented endpoints across AWS, Azure, and GCP simultaneously.
