CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
42Crunch API Security Platform
Security teams building APIs at scale need 42Crunch API Security Platform to catch BOLA and BFLA vulnerabilities before runtime, which most DAST tools miss because they don't understand OpenAPI contracts. The platform scores high on PR.DS (Data Security) and DE.CM (Continuous Monitoring) by enforcing schemas at runtime without proxying traffic through 42Crunch's infrastructure, meaning your data stays in your control. This isn't the right fit if your API footprint is small or static; the value compounds when you're shipping dozens of endpoints across multiple teams and need automated scanning in CI/CD plus real-time request blocking.
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.
