Cloud security review vs penetration test: which assessment fits your risk

Both evaluate technical exposure. Sorami audits configuration from the inside in one, and attempts active exploitation in the other.

Last reviewed: · 4 min read

A cloud security review audits configuration, identity and architecture from the inside, using read-only access. A penetration test attempts exploitation from outside, against running systems. Sorami scopes the review first where baseline controls are unverified, because an offensive test on an unreviewed foundation returns configuration errors rather than exploitable logic.

Two different engineering questions

A cloud security review asks whether your control plane, network segmentation and IAM policies meet defensive baselines. An engineer examines configurations, identity graphs and architectural documentation to find structural weaknesses before an incident occurs.

A penetration test asks whether an attacker can breach your perimeter, bypass authentication or pivot between tenants. A tester simulates adversarial techniques against running systems to confirm whether theoretical weaknesses are actively exploitable.

When to choose a cloud security review

  • You migrated infrastructure to the cloud and need to verify baseline controls.
  • IAM roles and service accounts expanded across teams without centralised guardrails.
  • You need comprehensive visibility into storage encryption, audit logs and networking.
  • Leadership wants an engineering audit of the control plane before releasing budget.

When to choose a penetration test

  • An enterprise customer or auditor demands proof of third-party offensive testing.
  • You are launching a web application, mobile app or public API.
  • You need to verify whether multi-tenant data boundaries withstand hostile manipulation.
  • Your engineering team deployed major architectural changes and requires adversarial validation.

Common misconceptions

  • Running an automated posture scanner is not an engineering security review.
  • A penetration test does not audit all cloud configurations or storage policies.
  • Passing an offensive penetration test does not guarantee an account is configured safely.
  • Conducting both together without fixing baseline configuration issues wastes testing budget.

Questions before you book

Practical answers.

Can a cloud security review replace a penetration test?

No. A review inspects architecture, policies and configurations, but does not execute attacks. Auditors or enterprise customers requiring evidence of exploit resistance typically demand an offensive penetration test.

Which assessment should we perform first?

Start with a cloud security review if your baseline controls, IAM policies or network segmentation are unverified. Running an offensive test on an unreviewed foundation often finds obvious configuration errors rather than deep exploitable logic.

Do cloud providers require advance notice before a penetration test?

AWS, Azure and Google Cloud permit penetration testing of customer resources without prior notification for standard compute services. However, denial of service and resource exhaustion testing remain strictly prohibited.

What access is required for each assessment?

A cloud security review requires read-only audit roles in your control plane and architectural documentation. A penetration test requires target URLs, API endpoints, test tenant accounts and explicit written authorisation.
