Frequently Asked Questions

Everything you need to know about GKE security with TigerGate

TigerGate uses GCP service accounts with Kubernetes Engine Viewer and Kubernetes Engine Cluster Viewer roles. You can use Workload Identity to grant TigerGate access, or provide a service account key. No cluster-admin access is required.
Yes! TigerGate fully supports GKE Autopilot clusters. We validate Autopilot-specific security controls and verify that Google-managed security features like Shielded GKE Nodes, Workload Identity, and Pod Security Standards are properly configured.
TigerGate runs GKE-specific checks including: Workload Identity configuration, Binary Authorization policies, Shielded GKE Nodes (Secure Boot, vTPM), VPC-native clusters, private clusters, master authorized networks, Cloud Logging/Monitoring, release channels, and intranode visibility.
TigerGate complements GKE Security Posture by providing full CIS Kubernetes Benchmark coverage (not just a subset), cross-project visibility, historical trending, and integration with your existing security workflows. You get deeper checks and multi-cloud consistency.
Yes! TigerGate supports multi-project scanning. Use a service account with organization-level permissions, or configure per-project service accounts. All clusters appear in a unified dashboard with project-level filtering.
