42Crunch API Audit is a commercial api security tool by 42Crunch. StackHawk API Discovery is a commercial api security tool by StackHawk. 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:
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.
Platform and product security teams managing microservices across multiple repositories need StackHawk API Discovery to stop shipping undocumented APIs into production; it's the only tool that maps your attack surface directly from code commits and flags shadow endpoints before they become breach vectors. The AI-generated OpenAPI specs and continuous inventory updates mean your API catalog stays in sync with actual deployments, which NIST ID.AM asset management requires but most teams skip entirely. Skip this if your APIs are mostly monolithic REST services behind a single gateway,you'll pay for microservices and serverless detection you don't need.
