Cloud Penetration Testing

Expert-led, manual cloud security testing, for AWS, Azure, Google Cloud, and Oracle.

>Migrating to the cloud shifts your attack surface, not your responsibility for securing it. Misconfigurations, overpermissioned identities, exposed storage buckets, and weak access controls are among the most common, and most consequential, vulnerabilities in cloud environments today. Our CREST-accredited consultants test your cloud infrastructure manually, the way a real attacker would, to find what automated tools consistently miss.

Cloud Test Overview

What Is A Cloud Penetration Test?

A cloud penetration test is a structured, expert-led security assessment of your cloud environment, examining your identity and access management configuration, network controls, storage security, compute instances, and the services your organisation depends on. Unlike automated cloud security posture management (CSPM) tools, our consultants actively attempt to exploit misconfigurations and chain vulnerabilities together to demonstrate real-world attack impact.

Cloud environments are complex, fast-moving, and frequently misconfigured. Research consistently shows that the majority of cloud security incidents are caused not by zero-day exploits, but by misconfigured services and overpermissioned identities that automated tooling flags but doesn’t validate. Manual testing closes that gap.

Cloud Security

The Shared Responsibility Model

Every major cloud provider operates on a shared responsibility model: the provider secures the underlying infrastructure, but the security of what you deploy on top of it is your responsibility. That means your IAM configuration, your storage bucket policies, your network security groups, and your application layer are all yours to secure, and ours to test.

Many organisations assume their cloud provider handles security end-to-end. A cloud penetration test is designed to challenge that assumption and identify exactly where your configuration falls short of what an attacker needs to cause real damage.

Cloud Platforms

What Cloud Platforms Do We Test?

Amazon Web Services

We assess the security configuration of your AWS environment across the services your organisation relies on, EC2 instances, S3 buckets, IAM users, roles and policies, VPCs, Lambda functions, RDS databases, and more. Our consultants understand how AWS services interact and how attackers move laterally across them.

Microsoft Azure

From Azure Active Directory and role-based access control through to Azure Kubernetes Service, App Services, and storage accounts - we test the full range of Azure services and identify misconfigurations that could allow an attacker to escalate privilege or access sensitive resources.

Google Cloud Platform

We assess IAM configuration, service account permissions, Cloud Storage bucket policies, compute instance security, and network controls across your GCP environment, identifying paths an attacker could exploit to move from limited access to broad control.

Oracle Cloud

Pentest Limited is a listed third-party test provider for Oracle Cloud Services, one of a select number of security companies approved by Oracle to conduct penetration testing against their platform. If your organisation runs on Oracle Cloud, we're well placed to help you test it.

Pentest Limited - Oracle Cloud Approved.

Pentest Limited is one of a select number of security companies listed by Oracle as an approved third-party penetration testing provider for Oracle Cloud Services. If your organisation runs on Oracle Cloud, you need a provider Oracle trusts to test it.

Cloud Test Coverage

What Our Cloud Testing Covers

Our cloud assessments are scoped to your environment and delivered manually. Every finding is the result of active investigation by our consultants, not automated scanner output.

Identity and Access Management (IAM)

> Overpermissioned users, roles, and service accounts
> Privilege escalation paths - misconfigured IAM policies & role assumptions
> Multi-factor authentication enforcement on privileged and administrative accounts

Storage & Data Exposure

> Publicly accessible storage buckets, blobs, and object stores
> Sensitive data exposure via misconfigured access policies and ACLs
> Encryption configuration for data at rest and in transit

Network Configuration & Segmentation

> Security group, firewall rule, and network ACL assessment
> Unnecessary exposure of management interfaces and internal services
> VPC peering, transit gateway, and network segmentation controls

Compute & Workload Security

> EC2, virtual machine, and container instance configuration
> Metadata service exposure and SSRF-to-cloud-credential attack paths
> Container and Kubernetes security configuration (AKS, EKS, GKE)

Logging, Monitoring, and Detection

> CloudTrail, Azure Monitor, and GCP audit logging configuration
> Alerting on suspicious behaviour, failed authentication, and privilege escalation
> Data loss prevention controls and sensitive data transfer detection

Application & API Security

> Serverless function security - Lambda, Azure Functions, Cloud Functions
> API Gateway configuration and authentication controls
> Secrets management - hardcoded credentials, exposed API keys, and insecure secret storage

Our Test Process

Putting Your Cloud Environment To The Test

Every cloud test goes through a rigorous process to ensure you get the best possible results. Below we outline the key stages our testing goes through:.

Understand Your Requirements

Cloud environments vary enormously in complexity, scale, and the services they use. We begin every engagement by understanding your architecture, your compliance requirements, and what a successful assessment looks like for you, before putting forward a bespoke scoping proposal tailored to your environment.

Manual, Expert-Led Testing

Your test is carried out by directly employed, CREST-certified consultants with hands-on experience across AWS, Azure, GCP, and Oracle Cloud. We use specialist cloud testing tooling to support our work, but every finding is the result of manual investigation and active exploitation, not automated output.

Reporting Tailored To Your Organisation

Our reports are written for real audiences. Technical findings include full exploitation detail, demonstrated impact, and clear remediation guidance for your cloud and DevOps teams. Executive summaries give leadership what they need and where required, findings can be mapped to compliance frameworks and benchmarks.

Post-Test Remediation Support

Our consultants remain available after the delivery of our report to answer questions, support your remediation efforts, and can provide fix checks to confirm vulnerabilities have been resolved or mitigated. Additional documentation for compliance and audit purposes is available on request.
