GCP penetration testingthat proves what scans missed.
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.
The window from vulnerability discovery to exploitation has gone from weeks to hours.

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.
Why a Security Command Center scan isn't a pentest
A flag passed is not a finding proven.
Security Command Center, Forseti, and Cloud Asset Inventory report what your GCP project looks like. A GCP penetration testing engagement reports what an attacker can do with it. SecureLayer7 operators chain those flagged findings into the proof-of-exploit your dev team can fix and your auditor will accept.
IN SCOPE.
Where we look across your GCP estate.
Workload Identity, impersonation paths, Org-level IAM, Cloud Identity federation.
Metadata server access, node-pool escape, Cloud Run service-account scope, Cloud Build trust.
Bucket IAM, dataset sharing, authorized views, KMS key rings, snapshot lineage.
Shared VPC, VPC Service Controls, Private Service Connect, peering gaps across projects.
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.

GCP testing, UK answers.
How do you test Workload Identity Federation?
Cross-cloud trust paths from AWS or Azure into GCP. Findings cite the federated-pool config and the NCSC Principle 9 identity control.
Do you cover Org Policy bypass?
Yes. Org-policy escape, inherited tag abuse and constraint drift. Each maps to a UK GDPR Art. 28 processor-control finding.
Can you align to Cyber Essentials Plus?
Yes. CE+ control set sits inside the report appendix. GCP CIS Benchmark v3.0 forms the second appendix.
Where do test logs live?
europe-west2 by default. KMS-protected bucket, retention deleted at engagement close, ICO breach-flow documented per UK GDPR Art. 33.
