Certified Kubernetes Security Specialist (CKS)

The Certified Kubernetes Security Specialist (CKS) program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation, to help develop the Kubernetes ecosystem.

As one of the highest velocity projects in the history of open source, Kubernetes use is exploding. The Cloud Native Computing Foundation is committed to growing the community of Kubernetes-knowledgeable security specialists, thereby enabling continued growth across the broad set of organizations using the technology.

Certification is a key step in that process, allowing certified security specialists to quickly establish their credibility and value in the job market, and also allowing companies to more quickly hire high-quality teams to support their growth.
