The 42Crunch API Security Platform revolves around OpenAPI definitions as the single source of truth. It audits API contracts against hundreds of security checks, generates a security score, and provides concrete remediation guidance to developers. From these contracts, it can generate policies for an API-native firewall that enforces strict request validation and protects APIs at runtime. The platform integrates with IDEs, CI/CD pipelines, and cloud environments to automate scanning and policy deployment, providing a continuous feedback loop from design to runtime.
