API Security Platform
Fix Your APIs Today, Prevent API Breaches Tomorrow


Enabling Continuous API Security

42Crunch enables a standardized approach to securing APIs that automates the enforcement of API security compliance across distributed development and security ecosystems.

42Crunch brings API semantic, code hygiene and data definition to all APIs. Security teams now gain oversight and governance of the policy enforcement throughout the API lifecycle.

Empower your developers to implement security as code in their workflow. 42Crunch is embedded in IDEs, code repositories & CI/CD environments.

Security is never the bottleneck. Enable your developers to focus on high-value work to improve and accelerate the delivery of world-class APIs.

Security audit and scanning become automated checks ensuring that insecure code never makes it to the master branch and production deployment. Runtime protection policies get automatically redeployed with each API change.

Traditional solutions generate an unacceptable volume of false positives. Eliminate noise and only see the issues that actually matter and need to be fixed.

Eliminate friction between development and security teams and automate protection to ensure that your API security program has unlimited scale.

Secure APIs with 42Crunch

42Crunch API Security Platform

Enterprises deploy 42Crunch to navigate the challenge of enforcing API security across a complex landscape of distributed development teams and multiple technical architectures. 42Crunch automates the enforcement of API security policies and standards across these development and security ecosystems. We help security take back control of API Governance and give development the tools they need to build safer APIs.

How it Works

Our API Security platform leverages the OpenAPI Specification (OAS) to enable enterprises adopt a design and security first approach to protecting APIs. Security is designed and coded in at API design time and enforced automatically throughout the API  lifecycle from design, development, testing, deployment and at runtime.

Ready for DevSecOps

42Crunch is uniquely designed to enable a collaborative DevSecOps approach to API security. All teams: API architects, developers, QA, security, operations – get a shared view of API security, its shared definition, and shared understanding of what needs to be done to improve it.  Combining shift-left with shield-right has never been so easy!


Effortlessly design the most secure API contracts with tools you'll love.


Turn error-prone manual API security into fool-proof production deployment.


Securely and confidently
deploy your APIs.

Deploy Anywhere!

Use 42Crunch 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(®). 42Crunch also integrates with existing collaborative developer tooling such as GitHub, GitLab and, or Azure pipelines.


The overall score awarded to the 42Crunch API Security Platform is a 5/5 start - the highest rating I've ever given a vendor thus far.
