Vulnerable REST API with OWASP top 10 vulnerabilities for security testing.
VAmPI is a vulnerable API made with Flask and it includes vulnerabilities from the OWASP top 10 vulnerabilities for APIs. It was created as I wanted a vulnerable API to evaluate the efficiency of tools used to detect security issues in APIs. It includes a switch on/off to allow the API to be vulnerable or not while testing. This allows to cover better the cases for false positives/negatives. VAmPI can also be used for learning/teaching purposes. You can find a bit more details about the vulnerabilities in erev0s.com.

Virtual Kubernetes and Multi-Tenancy.
Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.
Virtual clusters are fully functional Kubernetes clusters nested inside a physical host cluster providing better isolation and flexibility to support multi-tenancy. Multiple teams can operate independently within the same physical infrastructure while minimizing conflicts, maximizing autonomy, and reducing costs.
