Frequently Asked Questions

What is 42Crunch and what does it do?

42Crunch is a leading API and AI security platform that helps organizations discover, test, secure, and continuously monitor APIs across development and runtime environments. It provides automated API security testing, OpenAPI security auditing, runtime protection, and AI API security controls to protect against modern application and AI-driven threats.

How does 42Crunch improve API security across the SDLC?

42Crunch integrates API security throughout the software development lifecycle (SDLC) that enables a proactive, shift-left approach while maintaining runtime protection. It

  • Performs static and dynamic API security testing
  • Audits OpenAPI specifications for vulnerabilities and misconfigurations
  • Enforces API security governance policies
  • Integrates into CI/CD pipelines for DevSecOps automation

Provides runtime API threat detection and protection

Why is API security critical for modern applications?

APIs are the backbone of cloud-native, microservices, and AI-powered applications. They are also a primary attack surface. Poorly secured APIs can lead to:

  • Data breaches
  • Broken authentication and authorization
  • Injection attacks
  • Business logic abuse
  • Agentic AI exploitation

42Crunch helps prevent these risks through automated API security testing and continuous runtime monitoring.

How does 42Crunch secure AI-powered APIs and AI agents?

42Crunch extends API security to AI and generative AI systems by:

  • Securing AI model APIs and inference endpoints
  • Detecting prompt injection and API misuse
  • Enforcing authentication and authorization controls
  • Monitoring AI API traffic for anomalies and abuse
  • Supporting governance for AI-driven applications

This ensures AI systems are protected from API-based attacks and misuse.

What makes 42Crunch different from traditional application security tools?

Unlike traditional AppSec tools that focus on general web vulnerabilities, 42Crunch is purpose-built for API security. It provides:

  • Deep OpenAPI contract analysis
  • API-specific vulnerability detection
  • Continuous API security posture management
  • Runtime API security enforcement
  • Enterprise-grade governance for API ecosystems

This specialization makes it uniquely effective for modern API-first and AI-driven environments.

Does 42Crunch support DevSecOps, IDE and CI/CD integration?

Yes. 42Crunch integrates directly into:

  • IDE such as VSCode, Jetbrains and Eclipse
  • CI/CD pipelines (GitHub Actions, GitLab CI, Azure DevOps, Jenkins)
  • API gateways
  • Kubernetes environments
  • Cloud platforms (AWS, Azure, GCP)

It enables automated API security testing and policy enforcement without slowing development.

Who should use 42Crunch?

42Crunch is designed for:

  • Security and engineering teams tasked with build and protecting API ecosystems
  • DevSecOps teams embedding API security into pipelines
  • Cloud-native organizations running microservices
  • Enterprises deploying AI-powered applications
  • Companies managing large-scale API portfolios

It is especially valuable for organizations where APIs are mission-critical to business operations.
