42Crunch is a security platform for the API lifecycle, from design and development to production. It supports a "secure by design" approach, using OpenAPI contracts to audit for vulnerabilities and enforce security policies.
The tool is designed for development, DevSecOps, security, and operations teams. It provides static auditing, dynamic scanning, and a runtime micro-firewall to protect APIs from threats and vulnerabilities.
For organizations using agentic AI, 42Crunch provides guardrails to manage how AI agents interact with enterprise APIs. This is intended to help organizations integrate AI while maintaining control over core business systems.
Buyers should confirm if their environment supports the required IDE and CI/CD integrations and whether they have established OpenAPI contracts, as the platform's functionality relies on these definitions.
Key Features
Performs over 300 checks on OpenAPI contracts to identify security vulnerabilities and adherence to specifications during the design phase.
A dynamic testing tool that sends traffic to REST APIs to validate that they conform to their design and reject unexpected traffic.
A micro-firewall that enforces an allowlist of valid operations based on the API's OpenAPI contract at runtime.
Deterministic security controls designed to govern the interactions between AI agents and enterprise APIs.
Helps build OpenAPI contracts using traffic data, Postman collections, or existing partial files.
Thresholds in CI/CD pipelines that may prevent APIs from being deployed to production if they do not meet security scores.
Use Cases
Using static audits and dynamic scans to find and fix vulnerabilities before code is merged into production.
Deploying a micro-firewall to block unauthorized operations on production APIs based on the API contract.
Implementing guardrails to secure the interactions between AI agents and enterprise data workflows.
Maintaining a view of the API portfolio to support adherence to corporate security policies and OWASP standards.
