Cloud Penetration Testing

In the cloud, identity is the perimeter. We find the misconfigurations and privilege-escalation paths that turn one leaked key into a full account takeover.

Attack path focus LIVE

  • AWS, Azure and Google Cloud
  • IAM escalation path analysis
  • Kubernetes & serverless coverage
  • CIS benchmark gap report

Overview

Most cloud breaches don't involve exotic exploits. They start with an over-permissive role, a leaked access key in a repository, a publicly readable storage bucket or a compromised CI/CD runner — and move quickly from there.

Our cloud penetration tests combine a configuration review against recognised benchmarks with hands-on exploitation. Starting from realistic footholds — an external attacker, a compromised developer credential or a vulnerable workload — we map how far an attacker could get and which data they could reach.

The result is a prioritised view of the attack paths that matter, not a list of thousands of low-value configuration warnings.

What's included

Identity & accessIAM policies, roles, service accounts, trust relationships and privilege escalation.
Data exposureStorage buckets, databases, snapshots and secrets accessible beyond intended boundaries.
Compute & containersVMs, Kubernetes (EKS/AKS/GKE), container escape and workload identity.
ServerlessFunctions, event triggers, environment secrets and execution roles.
NetworkSecurity groups, private endpoints, peering and exposed management interfaces.
CI/CD & secretsPipeline permissions, runner security and secrets management.

Our approach

  1. Read-only access & inventoryWe review configuration with read-only credentials and build an asset and identity map.
  2. Benchmark reviewSettings are compared against CIS benchmarks and provider best practice.
  3. Attack path analysisWe identify privilege-escalation and lateral-movement paths through IAM and services.
  4. Exploitation (agreed scope)Selected paths are safely exploited to prove impact.
  5. Report & hardening planPrioritised fixes, infrastructure-as-code recommendations and a retest.

Frequently asked questions

Do we need permission from our cloud provider?

AWS, Azure and Google Cloud permit customers to test their own resources for most services without prior approval, subject to their published policies. We review the current policy with you during scoping.

Is a configuration review the same as a cloud pentest?

No. A review checks settings against benchmarks; a penetration test also proves exploitability by following attack paths to sensitive data.

Can you test multi-account or multi-cloud environments?

Yes. We scope by accounts, subscriptions or projects and prioritise production and identity-critical environments.
