GCP penetration testingfrom one binding to project Owner.
Manual GCP penetration testing for Google Cloud Platform. We hunt named bug classes: Workload Identity Federation confusion, service account impersonation, Cloud Run trigger replay, GKE node pool escape, VPC Service Controls bypass.
GCP surfaces
VPC · IAM · GKE · Workload Identity Federation. One pod, one method, four control planes.
Working proof
Every finding ships with a working exploit transcript, code-level fix guidance, and a free re-test.
Compliance-ready
PCI DSS, HIPAA, ISO/IEC 27001, SOC 2 Type II. Your auditor reads the same artefact.
A VPC-SC misconfiguration leaks Workload Identity tokens cross-project.

On record
What we test
Four GCP surfaces. One method.
Each surface scoped against named bug classes. We chain across them. A Workload Identity token misuse can land in BigQuery, exfiltrating data tagged for VPC Service Controls.
VPC + perimeter
VPC Service Controls bypass, firewall egress oversight, Identity-Aware Proxy misconfig, Cloud NAT exposure. Lateral movement chained inside the perimeter.
IAM + identity
Service account impersonation via iam.serviceAccounts.actAs, allow-policy plus deny-policy interaction gaps, Organization policy drift, custom-role privilege creep.
GKE + workloads
Node pool escape via privileged pod, GKE Autopilot constraint bypass, Workload Identity binding abuse, metadata API exposure inside the pod.
Storage + secrets
Cloud Storage bucket IAM, signed-URL leakage, Secret Manager accessor scope, Cloud KMS key policy bypass, Firestore unauth read.
From flag to exploit.
A flag passed is not a finding proven.
A passing posture check isn't a closed path. We chain flagged GCP findings, an over-broad service account, a token reachable from a workload, a permissive IAM binding, into the proof-of-exploit your dev team can fix and your auditor will accept.
GCP PENTEST METHODOLOGY.
Eight phases. One artifact.
Each GCP penetration testing engagement moves through eight phases and lands on one named artefact: a CREST-mapped severity rubric scored against your project invariants.
