TL;DR: Cloud security failures often begin with governance gaps rather than provider defects, as Google Cloud’s shared responsibility model still leaves customers accountable for overly permissive service accounts, exposed storage buckets, firewall exposure, and guest OS patching, according to Intruder. The implication for IAM and cloud teams is that least privilege, access scoping, and continuous posture visibility remain the real control boundaries.
Editorial analysis by NHI Mgmt Group, based on content published by Intruder: “Google Cloud Security: What’s Really On Your Shoulders”.
Key questions
Q: What breaks when service accounts have more privilege than the workload needs?
A: Excessive service-account privilege turns a single compromise into broad cloud access, because the attacker inherits the workload’s permissions instead of having to escalate.
Q: Why do public buckets and wide-open firewall rules create so much cloud risk?
A: They convert configuration choices into direct exposure.
Q: How can teams tell whether shared responsibility is being governed effectively?
A: Look for explicit ownership of every layer the customer controls, evidence that privilege is scoped to the task, and continuous scanning for public exposure and patch gaps.
Practitioner guidance
- Audit service account privilege levels Identify every service account, workload identity, and automation credential with project-wide or admin access.
- Inventory public exposure paths Scan storage buckets, public IPs, and firewall rules together so that publicly reachable assets are assessed as one exposure problem rather than separate silos.
- Separate PaaS and IaaS ownership Write down which security layers Google manages and which layers your team manages for each service model.
Bottom line: Cloud risk in Google Cloud still comes largely from customer-controlled identity, storage, network, and patching decisions.

Shared responsibility failure is usually an identity governance failure first: the cloud provider may secure the platform, but it cannot determine whether a service account needs admin-level access or whether a bucket should be public. That judgment sits with the customer’s IAM and cloud governance programme. The operational lesson is that cloud responsibility models only work when identity scope and exposure settings are owned as continuously managed controls.
A few things that frame the scale:
- 82% of breaches involved data stored in the cloud, according to IBM (2024).
A question worth separating out:
Q: When should cloud teams prioritise posture visibility over another point-in-time hardening review?
A: They should prioritise it whenever workloads change frequently, service accounts are used for automation, or public exposure can appear through routine configuration drift. Point-in-time reviews miss the moment when a bucket becomes public or a firewall rule opens a service. Continuous visibility is the safer control because it sees responsibility failures as they emerge.
