-> **Wondering about Preflight?** Preflight was the name for the project that was the foundation for the Jetstack Secure platform. It was a tool to perform configuration checks on a Kubernetes cluster using OPA's REGO policy. We decided to incorporate that functionality as part of the Jetstack Secure SaaS service, making this component a basic agent. You can find the old Preflight Check functionality in the git history ( tagged as `preflight-local-check` and you also check [this documentation](https://github.com/jetstack/jetstack-secure/blob/preflight-local-check/docs/check.md).
+"The agent" manages your machine identities across Cloud Native Kubernetes and OpenShift environments and builds a detailed view of the enterprise security posture.
