42Crunch API Protection vs TeejLab API Discovery Manager: Side-by-Side Comparison (2026)

42Crunch API Protection

Teams protecting microservices architectures should pick 42Crunch API Protection for its positive security model that enforces OpenAPI contracts at runtime, catching malformed requests before they reach application code. The tool covers all ten OWASP API vulnerabilities natively and deploys directly from CI/CD pipelines into containers and API gateways without requiring code changes. Skip this if you need a broader API management platform; 42Crunch is purpose-built for threat prevention, not governance or monetization.

TeejLab API Discovery Manager

Mid-market and enterprise security teams drowning in shadow APIs and undocumented integrations should start with TeejLab API Discovery Manager because it finds what you don't know exists through repository scanning and network traffic analysis, then maps compliance gaps against actual API behavior. The platform covers NIST ID.AM and ID.RA thoroughly, giving you the asset inventory and risk visibility needed before you can govern, plus it integrates directly into CI/CD pipelines so discovery happens continuously, not as a quarterly audit exercise. Skip this if your API surface is small or your APIs are predominantly third-party managed; the value compounds only when you have dozens of internal and inherited services that nobody fully owns.
