Cloud infrastructure penetration testing (AWS, Azure, GCP)

80% of cloud incidents originate in a misconfiguration, not a zero-day. We audit your cloud infrastructure before an attacker exploits it.

Why does the cloud need a different pentest?

The cloud's shared responsibility model puts the security of configuration, identity and data in the customer's hands. A public S3 bucket, an IAM role with excessive permissions or an EC2 instance with hardcoded credentials are vectors that automated scanners don't contextualize. You need a team that thinks like an attacker with deep knowledge of AWS, Azure and GCP.

Scope

  • IAM policy review and privilege escalation in AWS/Azure/GCP
  • Detection of public S3 buckets, Azure blobs and GCS with sensitive data
  • Enumeration of exposed resources: APIs, serverless functions, databases
  • Network assessment: VPC, security groups, Network ACLs, peering
  • Secrets and credentials in instance metadata, environment variables and code
  • Kubernetes assessment (EKS, AKS, GKE): RBAC, pod security, network policies
  • Review of CI/CD pipelines and container registries
  • Alignment with CIS Benchmarks for AWS, Azure and GCP
  • Assessment against the MITRE ATT&CK Cloud Matrix

Methodology

  1. Reconnaissance and enumeration: Enumeration of all cloud resources via APIs, specialized tools (Pacu, ScoutSuite, Prowler) and manual analysis.
  2. IAM and privilege analysis: We map all roles, policies and privilege escalation paths to determine the blast radius of a compromised account.
  3. Configuration exploitation: We exploit the misconfigurations found in a controlled way to demonstrate real impact: data access, lateral movement or full account control.
  4. Secrets and data exposure analysis: We look for exposed credentials in metadata, code, pipelines and backups.
  5. Report and remediation: Severity classification mapped to CIS Benchmarks. Remediation plan prioritized by impact and effort.

Deliverables

  • Executive report with a cloud risk map
  • Technical report with evidence and PoC for each finding
  • Mapping of findings to CIS Benchmarks and MITRE ATT&CK Cloud
  • Hardening guide per cloud service (IAM, S3, EC2, Lambda...)
  • Security posture score before/after
  • Re-test included after remediation

Use cases

  • Cloud-native startups on AWS or Azure that need to certify their security to enterprise clients
  • Companies migrating on-premise infrastructure to the cloud for the first time
  • SaaS platforms with multi-tenant architecture in public cloud
  • Companies with Kubernetes in the cloud that suspect misconfigurations
  • Organizations subject to NIS2, ENS or ISO 27001 with cloud workloads

Frequently asked questions

Do you need admin credentials for cloud pentesting?

For a complete test, yes, we need an account with read permissions over all services. We can also perform a black-box test from the internet to assess external exposure. We recommend combining both approaches.

Can pentesting affect my production services?

We coordinate all tests to minimize impact. Destructive exploitation (deletion, data modification) always requires explicit approval and is done in test environments.

Do you cover multi-cloud architectures?

Yes. We have experience in environments combining AWS, Azure and GCP, as well as hybrid cloud + on-premise configurations.
