Google Cloud (GCP) Security Review
GCP Cloud Security Google Cloud (GCP) Security Review Our GCP security review assesses your Google Cloud environment against the CIS Google Cloud Foundation Benchmark, examining Cloud IAM, Cloud Storage, VPC firewall rules, Cloud KMS and logging to find the misconfigurations and excessive permissions that most often lead to cloud breaches.
Overview
What is a GCP security review?
A GCP security review is a structured assessment of your Google Cloud projects — covering Cloud IAM, Cloud Storage buckets, VPC and firewall rules, Cloud KMS, encryption and Cloud Logging — measured against the CIS Google Cloud Foundation Benchmark and Google's security best practice.
The goal is to surface public Cloud Storage buckets, over-privileged IAM bindings, permissive firewall rules and gaps in logging before attackers do, giving you a prioritised roadmap to a hardened GCP posture.
What you'll receive
- ✓Scoping: agreed GCP projects, folders and organisation-level settings
- ✓Testing: review of IAM, service accounts, Cloud Storage, VPC firewalls and logging
- ✓Executive report: a Google Cloud posture summary for stakeholders
- ✓Technical report: findings mapped to the CIS Google Cloud Foundations Benchmark
- ✓Remediation: prioritised guidance aligned to Google Cloud security best practices
- ✓Retest & debrief: a retest of fixes and a walkthrough call with your team
Why It Matters
The value of regular security reviews
Evaluate your controls
Regular security reviews enable organisations to comprehensively evaluate their security measures, including the effectiveness of controls, configurations, and policies.
Strengthen your posture
Identifying weaknesses allows organisations to strengthen their security posture and better protect their assets and data against evolving threats.
Meet compliance
Regular security assessments are essential for compliance with industry regulations and data protection laws, demonstrating your commitment to a secure environment.
High-Level Methodology
A structured, five-phase cloud review
Scoping & Access
We agree the organisation, folders and projects in scope, and the objectives of the review. You provision read-only roles (typically Viewer plus Security Reviewer) so we can assess configuration safely, without making changes to your environment.
Automated Benchmarking
We assess your projects against the CIS Google Cloud Foundation Benchmark, using trusted tooling to rapidly flag insecure defaults, disabled controls and drift across the whole environment.
Manual Service Review
Our consultants manually review each Google Cloud service your environment actually consumes — for example Cloud Storage, Compute Engine, Cloud SQL, GKE and Cloud Functions — assessing how each is configured, exposed and connected in the context of your real workloads. This is where we find the issues automated tooling misses.
Identity & Privilege Analysis
We examine Cloud IAM roles, members, bindings and service accounts to map effective permissions, then trace the privilege-escalation and lateral-movement paths an attacker could chain across your GCP organisation and projects.
Reporting & Remediation
We deliver a clear report that prioritises findings by real-world risk, with GCP-specific, actionable remediation guidance. We're happy to walk your team through the results and support any follow-up validation once fixes are in place.
FAQ
Frequently asked questions
Which GCP services do you assess?
We review the Google Cloud services in scope — including Cloud IAM and service accounts, Cloud Storage, VPC and firewall rules, Compute Engine, Cloud SQL, GKE, Cloud KMS and Cloud Logging — against the CIS Google Cloud Foundation Benchmark.
How much does a GCP security review cost?
The cost depends on the number of GCP projects in scope, the range of services deployed and the depth of review required. Contact us for a customised quote.
What access do you need to review our GCP environment?
Typically we request read-only roles (such as Viewer plus Security Reviewer) so we can review configuration safely without making changes. We agree the exact scope and access with you before any work begins.
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan identifies potential weaknesses in your systems, whilst a penetration test attempts to actively exploit those weaknesses to determine their real-world impact. A penetration test goes beyond simply identifying vulnerabilities by demonstrating how they can be exploited and what data could be accessed.
What are the most common issues you find?
Recurring findings include public Cloud Storage buckets, over-privileged IAM bindings and service-account keys, firewall rules open to the internet, missing MFA, unencrypted data, and gaps in Cloud Logging.
