Frequently Asked Questions

Everything you need to know about K3s security with TigerGate

TigerGate connects to K3s clusters using kubeconfig with a ServiceAccount token. K3s generates a kubeconfig at /etc/rancher/k3s/k3s.yaml. You can create a read-only ServiceAccount or use the k3s-generated admin token for initial scans.
Yes! TigerGate fully supports K3s on ARM64 and ARMv7 devices including Raspberry Pi, NVIDIA Jetson, and other edge/IoT hardware. Our lightweight scanning is optimized for resource-constrained environments.
TigerGate runs K3s-specific checks including: embedded component security (containerd, Flannel, CoreDNS, Traefik), SQLite/etcd backend encryption, secrets encryption configuration, hardening flags validation, local storage security, and embedded service exposure.
Yes! TigerGate validates that K3s is configured with --secrets-encryption flag and that the encryption configuration is properly set up. We check the encryption provider configuration for at-rest secrets encryption.
Yes! TigerGate supports air-gapped K3s deployments. You can run the scanner as an in-cluster agent or export scan results to a file for offline analysis. We validate air-gap specific configurations.
