API Security Done Right.

Let us worry about security so you don't have to.

There's No Guesswork Required

You do not have to rely on security by obscurity, manually configured rules, or hope that some anomaly detection can report an attack. With 42Crunch, there is no more guesswork required. Our approach is to rely on the API contract, leveraging the OpenAPI (aka Swagger) de-facto standard. What is described by the contract is accepted, what is not is rejected. It’s as simple and powerful as that. 

We'll Do the Heavy Lifting

42Crunch was built to do the work - so you don’t have to. With 42Crunch, security audit and conformance scanning become automated checks ensuring that unsecure APIs never make it to the master branch and production deployment. Moreover, runtime protection policies get automatically redeployed with each API change, making sure that you can stay agile without compromising security.

We Know APIs

Our API security team comes from a wide background of WAF, API management, and white hat security companies. We are one of the active members of the Linux Foundation OpenAPI (formally Swagger) Initiative and reviewers of OWASP Top 10 for API Security. With us, you can be sure that your APIs are checked against the latest known risks and follow the latest best practices.

DevSecOps Becomes Effortless

Shifting left has never been so easy! 42Crunch gets everyone in the company speaking the same language with full visibility into all APIs, the current state of affairs, security levels, protection status, and report of any required security improvements. Collaboration becomes seamless, DevSecOps is enabled, and magic happens.

Designed for Flexibility

You can use our micro-API firewall to equally protect north-south and east-west traffic. Thanks to its low footprint, it can be deployed at scale on any container orchestrator such as Kubernetes, Amazon ECS or Red Hat OpenShift(®). Our runtime is fully compatible with existing API management solutions or API gateways and with microservices-based architectures.

Industry Analysts & Partners

Don't take it from us - listen to what industry analysts and our partners are saying about 42Crunch!


“While Azure Pipelines already had security testing extensions for various parts of the application stack, there had been a glaring gap of the one specifically designed for REST APIs. We are happy to see 42Crunch bridge that gap with their solution.”

Steven Murawski

“42Crunch’s ability to secure both the CI/CD pipeline & the runtime environment makes it a compelling candidate for any API security project. The development of the local agent for internal APIs, meanwhile, expands its dynamic scanning capabilities even further.”

Rik Turner

"As more APIs drive modern applications, we are seeing a strong demand for more efficient tools that integrate API security with CI/CD. By adding the 42Crunch security platform to our portfolio we can address this demand by offering customers new innovative API security tools that they can put right into their CI/CD pipelines."

Ruben van der Zwan

“Based on the resulting scores from each category in our API hacking lab, the overall score awarded to the 42Crunch API Security Platform is a 5/5 stars – the highest rating I’ve ever given a vendor thus far.”

"I've been waiting for basically this exact extension forever - the YAML support is fantastic. Thank you!"

"Excellent extension for editing / viewing OpenAPI specs, primarily when the specs are pretty big. The Swagger Editor is good, but you need to setup it and again need to switch from your main editor (which is VS Code) to something else - little bothersome! With this extension, you can do it side by side while writing code. Writing a new OpenAPI spec is also easier thanks to validation."
