What Is Cloud Penetration Testing?

Cloud penetration testing is a controlled security assessment designed to evaluate the resilience of your cloud-hosted infrastructure against real-world attack scenarios. Unlike traditional network testing, cloud assessments must consider shared responsibility models, provider policies, identity configurations, and API-driven architectures.

Our cloud penetration testing services cover:

  • Identity and Access Management (IAM) misconfigurations

  • Publicly exposed services and storage buckets

  • API and serverless vulnerabilities

  • Container security risks (Kubernetes, Docker)

  • Virtual network misconfigurations

  • Privilege escalation and lateral movement paths

  • Multi-account trust boundary weaknesses

For a strategic overview of methodologies and enterprise best practices, explore our Cloud Penetration Testing enterprise guide.

What We Test vs What Your Cloud Provider Secures

The most common cause of a cloud breach is a misunderstanding of the shared responsibility model. AWS, Azure, and GCP secure the infrastructure of the cloud. Everything you configure in the cloud remains your responsibility — and that is exactly where attackers operate.

LayerResponsibilityIn scope for testing?
Physical data centres, hypervisor, hardwareCloud providerNo — provider-owned
Managed service infrastructureCloud providerNo
IAM roles, policies and permissionsYouYes
Storage buckets, databases, network configYouYes
Operating systems, containers, workloadsYouYes
Application code and APIsYouYes
Secrets, keys and credentialsYouYes

A cloud penetration test targets everything in the “You” column. If a provider tells you they will test the cloud platform itself, they are describing something neither permitted nor useful.

Cloud Platforms We Test

AWS Penetration Testing

We perform security assessments aligned with AWS testing policies, evaluating:

  • IAM privilege escalation risks

  • S3 bucket exposure

  • EC2 misconfigurations

  • Security group weaknesses

  • Lambda & API Gateway vulnerabilities

  • Cross-account access risks

Microsoft Azure Penetration Testing

Our Azure assessments focus on:

  • Azure AD identity risks

  • RBAC misconfigurations

  • Storage account exposure

  • Network security group weaknesses

  • App Service and Function vulnerabilities

  • Privileged identity management risks

Google Cloud (GCP) Penetration Testing

Our GCP assessments focus on:

  • IAM roles, service accounts, and impersonation paths
  • Cloud Storage bucket exposure and ACL misconfiguration
  • Compute Engine and metadata server abuse
  • GKE (Kubernetes) cluster and workload identity risks
  • Cloud Functions and Cloud Run vulnerabilities
  • VPC and firewall rule weaknesses
  • Organisation and project-level trust boundary flaws

Container & Kubernetes Penetration Testing

Containerised workloads introduce an attack surface that traditional cloud scanning misses entirely.

  • Cluster configuration — exposed API servers, anonymous access, and weak RBAC
  • Workload identity — service account token abuse and cloud credential theft from pods
  • Container breakout — privileged containers, hostPath mounts, and escape to the underlying node
  • Image supply chain — vulnerable base images, embedded secrets, and untrusted registries
  • Network policy — flat pod networking and unrestricted east-west traffic
  • Managed services — EKS, AKS, and GKE-specific privilege escalation paths

Our Cloud Penetration Testing Methodology

1. Scope Definition & Asset Mapping

We define cloud accounts, subscriptions, regions, and exposed services within agreed scope.

We identify internet-facing assets and publicly accessible resources.

We analyze IAM configurations and privilege escalation pathways.

We simulate attacker techniques to evaluate blast radius.

Every vulnerability is manually validated and documented with proof-of-concept evidence.

Cloud Provider Testing Policies — Staying Compliant

Each cloud provider sets rules on what security testing is permitted without prior approval. We scope every engagement to stay inside them.

AWS — Customer-initiated penetration testing is permitted against approved services (EC2, RDS, Lambda, API Gateway, CloudFront and others) without prior approval. Simulated DDoS, DNS zone walking, and port flooding remain prohibited and require separate authorisation.

Microsoft Azure — Testing is permitted against your own resources under the Microsoft Cloud Unified Penetration Testing Rules of Engagement. Testing that impacts shared infrastructure or other tenants is prohibited.

Google Cloud — Testing your own projects is permitted without notifying Google, provided it complies with the Acceptable Use Policy and does not affect other customers.

In every engagement we:

  • Confirm which services are in scope and permitted
  • Exclude prohibited techniques by default
  • Rate-limit testing to avoid triggering availability impact
  • Document authorisation before any testing begins

You will never be exposed to a provider policy violation as a result of our testing.

What’s Included in Our Cloud Testing Engagements

  • Manual exploitation (no scan-only reports)

  • Identity misconfiguration analysis

  • Container and serverless security review

  • Executive risk summary

  • Technical remediation guidance

  • Compliance alignment (SOC 2, ISO 27001, PCI DSS)

  • Optional retesting after remediation

For enterprise pricing considerations, review our penetration testing pricing guide.

Cloud Penetration Testing vs Traditional Network Testing

Cloud testing differs from on-premises assessments due to:

  • Shared responsibility models

  • API-driven infrastructure

  • Identity-centric attack surfaces

  • Dynamic scaling environments

  • Cross-account trust relationships

Understanding these differences is critical for accurate risk assessment.

Cloud Penetration Testing Cost

Cloud engagement cost is driven by the number of accounts or subscriptions in scope, the services deployed, and whether container and application layers are included.

Engagement ScopeTypical Cost
Single account / subscription, focused scope$2K – $10K
Multi-account or multi-cloud environment$10K – $15K
Full cloud assessment incl. containers & applications$15K – $20K
Cloud red team (objective-based, detection testing)$20K – $25K+

Most organisations start with their production account, then expand across the estate once the methodology is proven.

Frequently Asked Questions

  • Yes, within provider policy guidelines. We ensure compliance with each cloud provider’s testing rules.
  • Costs depend on scope size, account complexity, exposed services, and compliance requirements. See our pricing guide for details.

  • Most engagements range from 1–3 weeks depending on scope.
  • Yes, optional retesting is available to validate remediation efforts.
  • No. Testing is rate-limited and scoped to avoid availability impact, and destructive techniques are excluded by default. Any potentially disruptive action requires explicit written approval and is scheduled around your change windows.
  • Both are possible. Production testing gives the most accurate picture of real exposure; where risk tolerance is low, we test a representative staging environment and validate configuration parity.
  • Most engagements use a read-only IAM role plus a defined scope of accounts and services. For grey-box testing we may request limited credentials to simulate a compromised user. Nothing is provisioned without your approval.
  • Yes. Multi-cloud estates frequently contain the weakest trust relationships — cross-cloud federation, shared identity providers, and hybrid connectivity back to on-premises networks.
  • Yes. Reports are structured to serve as evidence of independent security testing and map findings to the relevant control requirements.
  • At minimum annually, and after any significant architecture change, new account onboarding, or migration. Cloud environments change far more frequently than on-premises networks — a test is a point-in-time snapshot.
