CREST-Certified Cloud Penetration Testing for AWS, Azure and GCP

Cloud penetration testing is an authorised, time-boxed engagement in which CREST-registered testers attempt to compromise the confidentiality, integrity or availability of a cloud estate. Unlike automated posture scanning, it produces exploited attack chains with reproducible evidence, plus a hardening plan scoped to the estate.

Multi-cloud adds the connections between providers, which is where most modern breaches happen: federation paths, CI/CD with OIDC across clouds, replicated data, and split audit logging. A scanner licensed for one provider cannot see the trust path that crosses into another. We map the cross-cloud attack chains specific to your estate.

A single-cloud SMB estate is typically 4-5 days. A growth-stage estate or simple two-cloud setup is 7-10 days. A full enterprise landing zone or a three-cloud estate is 10-15 days. The 24-hour scope-to-quote includes a sizing call so you know the duration before you commit.

SMB engagements are £6,000-£10,000. Growth and mid-market engagements are £10,000-£18,000. Enterprise and multi-cloud engagements are £18,000-£28,000. The day rate for CREST-certified testers is £1,100-£1,400 per day. All tiers include free retests, executive and technical reports, a letter of attestation, and a walkthrough call.

Annually is the baseline that most audit, insurance and customer-due-diligence drivers expect. We also recommend a test before any significant architectural change, before a new production workload goes live, after an incident, and on entry to a new compliance regime.

All three providers permit penetration testing of customer-owned resources without prior notification, subject to their published rules of engagement (no denial-of-service testing, no testing of other tenants, certain services excluded). We confirm scope against the latest provider policies as part of the kick-off.

CREST registration is the most widely recognised UK assurance that the testers, the methodology and the company have been independently verified. Many UK regulated firms, insurers and government buyers require it. Our cloud testers are CREST-registered and the company is a CREST member.

We separate read-only enumeration from active exploitation and agree the rules of engagement up front. Active testing is scheduled into maintenance windows where appropriate. Storage and database actions are non-destructive by default. Every step is logged and reversible.

AWS, Azure and Google Cloud Platform, individually or as one multi-cloud estate. Each provider has its own attack surface across identity, storage, secrets, containers and serverless, and we test all three in depth using CIS Foundations as the floor.

Yes. Every finding is tagged to the relevant control reference: CIS Foundations Benchmarks, Cyber Essentials Plus, ISO 27001, SOC 2, the NCSC Cloud Security Principles, and FCA requirements. Your audit team submits the report directly without translation work.

From signed scope to active testing in as little as one business day where an incident, an audit deadline, or a regulator timeline requires it. The 24-hour scope-to-quote includes a sizing call, a fixed price, and a procurement-ready one-page scope.

Yes. A standard NDA is in place before any scoping discussion of your cloud estate. We operate under a project-specific agreement covering access handling, post-engagement data destruction, and confidentiality of all findings.
