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.
Comparison at a glance
| Dimension | Cloud security review | Penetration test |
|---|---|---|
| Scope | Control plane configurations, IAM policies, KMS encryption, network security groups and audit logging. | Public IP perimeters, APIs, web applications, container boundaries, cross-tenant isolation and privilege escalation. |
| Access required | Read-only cloud IAM audit credentials, infrastructure code repos, and architectural topology diagrams. | Scoped test credentials, API access tokens, network boundary definitions, and written rules of engagement. |
| Findings produced | Broad architectural weaknesses, excessive IAM permissions, unencrypted storage, and missing audit trails. | Validated exploit chains, authenticated privilege escalation proofs, and reproducible attack paths. |
| Best timing/trigger | Cloud migrations, platform redesigns, major infrastructure uplifts, or annual defensive baselines. | New product releases, third-party vendor due diligence, or customer audit requirements. |
| Blind spots | Cannot verify whether runtime application logic or complex token workflows resist targeted attacks. | Cannot assess control plane configurations or resources that lie outside the agreed testing boundary. |
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.
