42Crunch Review: Overview, Features, Pricing & Alternatives in 2025

Are API vulnerabilities keeping you up at night?

If you’re looking into 42Crunch, you’re probably struggling to lock down your APIs before attackers find the gaps. With so many security tools only catching problems after deployment, it’s tough to find a solution that secures APIs from day one.

Most platforms are great at monitoring, but you’re still wasting hours fixing API vulnerabilities after release—which means bugs slip into production and cause stress for your team.

That’s where 42Crunch comes in. Their developer-first API security platform bakes security into every step, from design audits and conformance scans to live micro-firewall protection, making it easy to build secure-by-default APIs—without the usual headaches.

Throughout this review, I’ll show you how 42Crunch helps your APIs pass security checks upfront and saves you time on painful rework.

In this 42Crunch review, I’ll share hands-on insights on its features, pricing options, integrations, and how it really compares to alternatives—so you can make a confident choice.

You’ll get the pros, cons, and the features you need to secure your APIs right from the start.

Let’s dive into the analysis.

42Crunch Overview

42Crunch has been focused on API security since 2015. Based in London, their core mission is helping you embed security throughout the complete API lifecycle.

They primarily target organizations that want to empower developers, not just overburden security teams. What really stands out is their developer-first security approach, making it much simpler for your engineering team to build and test secure APIs.

Their recent $17 million funding round and key partnerships with tech giants like Microsoft show strong momentum, a point I will analyze for you through this 42Crunch review.

Consequently, unlike competitors like Salt Security that emphasize runtime discovery, 42Crunch’s advantage is its proactive, security based on the API contract. This shift-left approach feels like it was designed by people tired of discovering critical vulnerabilities way too late in the process.

This developer-centric approach is clearly resonating. They work with major Fortune 500 firms, and their platform is now actively used by a community of over 1.6 million developers.

From my analysis, their entire strategy centers on a powerful “security-as-code” philosophy that integrates right into your existing CI/CD pipeline. This aligns perfectly with modern DevSecOps, making security a natural, non-disruptive part of your team’s everyday work.

Now let’s examine their capabilities.

42Crunch Features

Still pushing insecure APIs to production?

42Crunch features provide an integrated API security platform leveraging the OpenAPI Specification to secure your APIs end-to-end. Here are the five main 42Crunch features that transform your API security.

1. API Security Audit

Are you struggling to find API vulnerabilities early?

Waiting until runtime to find security flaws can lead to costly fixes and increased risk. This often delays your development cycle.

The API Security Audit performs static analysis on your OpenAPI definition, with over 300 checks, providing a security score and remediation guidance. What I love is how it flags issues like overly permissive schemas, allowing you to fix vulnerabilities before coding even starts. This feature is perfect for shifting security left.

This means you can easily identify and address design flaws, ensuring your API contracts are secure from day one.

2. API Conformance Scan

Are your live APIs behaving as expected, or are they hiding risks?

Without dynamic testing against your contract, live APIs can expose data or exhibit behaviors not in their specification. This opens doors for attackers.

The Conformance Scan dynamically tests live API endpoints against their OpenAPI contract, finding OWASP API Top 10 issues and schema violations. From my testing, it really shines at detecting undeclared data leaks or stack traces, ensuring runtime behavior matches design. This automated testing integrates seamlessly into your CI/CD pipelines.

This means you get continuous validation, catching real-world vulnerabilities and ensuring your deployed APIs conform to their secure design.

3. API Protection (Micro-Firewall)

Is your API gateway leaving gaps in runtime protection?

Traditional WAFs often struggle to understand API-specific logic, leading to false positives or missing sophisticated attacks. This leaves you vulnerable.

API Protection acts as a micro-firewall, inspecting full API transactions and blocking non-compliant or malicious requests in real-time. This is where 42Crunch shines, automatically tailoring policies to each API based on its contract, which virtually eliminates false positives and negatives.

What you get instead is precise, positive security that instantly stops attacks exploiting business logic vulnerabilities at the API layer.

4. Security Quality Gates (SQGs)

Are you struggling to enforce consistent security standards across all APIs?

Without clear security gates, vulnerable APIs can slip through into production, increasing your attack surface. This undermines your security posture.

Security Quality Gates allow you to define criteria an API must meet to pass an Audit or Scan, even failing a build in your CI/CD pipeline. I found this feature incredibly powerful for enforcing your security standards across all APIs, ensuring only secure code reaches production.

This means you can ensure every API meets your security bar, preventing vulnerable code from ever being deployed.

5. Integrations and Developer-First Tools

Are your security tools disrupting developer workflows?

Security checks often feel like roadblocks, forcing developers out of their familiar environments. This can create friction and slow down adoption.

42Crunch emphasizes integrating its tools into existing developer workflows, offering plugins for IDEs like VS Code and JetBrains, and CI/CD pipelines. Here’s the thing – developers can audit and scan directly within their coding environment, which drastically reduces friction. This approach truly makes security testing relevant to their current work.

So as a developer, you get immediate, actionable feedback, embedding security naturally into your development process.

These 42Crunch features work together to create a complete API security ecosystem that helps you build and deploy secure APIs at scale.
