Cloud Penetration Testing · United Kingdom
Cloud penetration testing. Identity is the perimeter now.
Nobody exploits a buffer overflow to breach your cloud. They find a role that trusts too much, a key in a repository, or a storage bucket that answers to anyone. We attack your AWS, Azure and Google Cloud estate the way that actually happens.

What is cloud penetration testing?
Cloud penetration testing is an authorised attack on your cloud environment: the identities, roles, permissions, storage, keys and pipelines that make it work. A tester proves which misconfigurations let an attacker move from a small foothold to your data.
Cloud breaches follow a different shape from on-premises breaches. The attacker rarely exploits software. They obtain one credential or one over-permissive role, then chain permissions until something grants them what they want. Almost every step is a configuration decision somebody made deliberately, for a reason that seemed sensible at the time.
Your provider secures the platform. You configure what runs on it, and that boundary is where the findings live. We test your side of it.
What we attack
Identity, storage, keys and pipelines
Every assessment starts where an attacker would: outside, watching, looking for the one door left ajar. We find it, then we show you the walk-through.
| Surface | What we look for |
|---|---|
| Identity and access management | Over-permissive roles, wildcard policies, privilege escalation paths between roles, and trust relationships that let one compromised workload assume another. |
| Storage exposure | Buckets, blobs and file shares readable or writable by more people than intended, including public exposure and cross-account access. |
| Secrets and keys | Credentials in code repositories, container images, environment variables, build logs and instance metadata. This is still the most common cloud entry point we find. |
| CI/CD and supply chain | Build pipeline permissions, which repositories can deploy to production, and whether a compromised developer account reaches your live environment. |
| Compute and containers | Instance metadata access, container escape, over-privileged Kubernetes service accounts and workloads running with more entitlement than the job needs. |
| Logging and detection | Whether your cloud audit trail would have recorded what we just did, and whether anyone would have seen it. |
What you get
The permission chains, drawn and ranked
Every assessment starts where an attacker would: outside, watching, looking for the one door left ajar. We find it, then we show you the walk-through.
- Every privilege escalation path we found, drawn from starting identity to final access
- The specific policy or role that needs changing, named, with the corrected permission
- A verdict on secrets exposure across code, images, logs and metadata
- What your logging captured, and what it missed
- Verified by a CREST-certified operator before it reaches you
- A year of unlimited re-tests through RTP Robin as your environment changes

What is cloud penetration testing?
Cloud penetration testing is an authorised attack on your cloud environment, focused on configuration and identity rather than software exploitation. A tester examines roles and permissions, storage exposure, secrets handling, build pipelines and workload entitlements, then proves which chains of permissions let an attacker reach your data from a realistic starting point. It tests your side of the shared responsibility boundary, which is where cloud breaches happen.
Do we need permission from AWS, Azure or Google to be tested?
For the customer-configured resources that make up almost all of a cloud penetration test, the major providers permit testing of your own environment without prior approval, subject to their published rules of engagement. Certain activities remain prohibited, denial-of-service testing in particular. We work inside each provider’s current policy, tell you before the engagement which activities are excluded, and never test infrastructure you do not own.
Is a cloud security posture tool enough?
A posture management tool is worth having and will flag a public bucket or an unencrypted volume quickly. What it does not do is chain findings together. It reports that a role has broad permissions and separately that a workload can assume that role, without concluding that a web application flaw therefore reaches your production database. A tester makes that connection and proves it, which is the difference between a list of misconfigurations and an attack path.
Can you test a hybrid environment?
Yes, and hybrid estates usually produce the most interesting findings. The crossing points are where controls are weakest: a domain-joined virtual machine in the cloud, a synchronised identity directory, a site-to-site connection that carries more traffic than anyone intended. We scope on-premises and cloud together so we can follow an attack across the boundary rather than stopping at it.
