Frequently Asked Questions

Everything you need to know about Rancher security with TigerGate

TigerGate can connect directly to the Rancher management server API, or to individual downstream clusters. For Rancher integration, you provide API keys with read-only access. For individual clusters, you can use kubeconfig or ServiceAccount tokens.
Yes! TigerGate supports all Rancher-managed Kubernetes distributions: RKE (Rancher Kubernetes Engine), RKE2 (the successor with built-in CIS hardening), and K3s (lightweight Kubernetes). Each has distribution-specific security checks.
TigerGate runs Rancher-specific checks including: Rancher auth provider configuration, global/cluster/project RBAC, Fleet GitOps security, RKE2 CIS hardened profile validation, cluster template security, Rancher webhook configuration, and multi-cluster network policies.
Yes! TigerGate validates that RKE2 clusters are properly configured with the CIS hardened profile. We check PSP/PSA configuration, audit logging, secrets encryption, network policies, and all CIS Kubernetes Benchmark requirements.
Yes! TigerGate fully supports Rancher Prime and Rancher Community Edition. We integrate with the Rancher API to discover and scan all managed clusters, providing enterprise-grade security visibility.
