CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Development teams shipping APIs at scale need 42Crunch API Audit to catch security gaps before code reaches production; its 300+ checks against OpenAPI contracts surface misconfigurations that static code analysis and WAFs typically miss entirely. The tool integrates directly into GitHub Actions and VS Code workflows, meaning security issues land in the developer's IDE rather than creating a separate audit queue weeks later. Skip this if your organization hasn't standardized on OpenAPI specs or if you need runtime API monitoring and threat detection; 42Crunch is a design-phase tool, not a request-level firewall.
Teams protecting APIs at the edge will find value in Curiefense's tight integration with Envoy proxy, which catches SQL injection and XSS before they reach your backend services. The free, open-source model means you can deploy it without vendor lock-in and audit the ruleset yourself, a rare advantage when evaluating WAF logic. Skip this if you need managed threat hunting, incident response, or a vendor to call when your API gets hit; Curiefense's single GitHub star signals a small maintenance surface and limited community tooling compared to commercial alternatives.
