Azure penetration testing assesses your Azure configuration and identities under the shared responsibility model. A key fact many guides still get wrong: Microsoft removed the notification requirement in June 2017 — you may test your own resources under the Microsoft Cloud Unified Rules of Engagement with no form and no notice. In Azure, identity is the control plane, so the highest-impact testing targets Microsoft Entra ID (consent phishing, over-privileged service principals), RBAC privilege escalation, and managed-identity abuse, alongside Blob Storage and Key Vault exposure. Microsoft's rules prohibit DDoS entirely and forbid exploiting a finding beyond initial identification — so we demonstrate impact within those limits. We map findings to CIS Azure Foundations Benchmark and include a retest.
// 01 What is Azure penetration testing?
Azure penetration testing is a manual assessment of your Microsoft Azure environment — your tenant, subscriptions, identities and resources — to find how an attacker could escalate access or reach your data. What makes Azure distinct from other clouds is that its security model is identity-centric: Microsoft Entra ID (formerly Azure AD) is the directory that governs access to everything, and Azure RBAC and managed identities layer on top. The consequence is that Azure attacks are usually identity attacks, and a test that only looks at network configuration misses where the real risk lives.
As with any cloud, the scope follows the shared responsibility model: we test security in the cloud — your Entra ID, RBAC, resource configuration and workloads — not Microsoft's underlying infrastructure, which is out of scope and off-limits.
// 02 Azure's testing policy: no notification needed
This is the single most misunderstood point about Azure testing, so it is worth stating plainly: you do not need to notify Microsoft to penetration test your own Azure resources, and have not since June 2017. Microsoft retired the old pre-approval model years ago in favour of the Microsoft Cloud Unified Penetration Testing Rules of Engagement, under which customers may test freely within the stated boundaries. Any provider or guide telling you to file a notification form is working from stale information.
What the rules do require is staying within clear limits. Microsoft explicitly prohibits certain actions, and the boundary around "identification versus exploitation" is stricter than on other clouds:
| Azure rule | Detail |
|---|---|
| Notification | Not required for your own resources |
| DDoS | Strictly prohibited under all circumstances |
| Beyond initial identification | No exploitation for lateral movement / privesc on shared services |
| Others' data or credentials | Prohibited |
| Phishing Microsoft staff | Prohibited |
| Third-party testers | Allowed with written authorization from the resource owner |
// 03 What we test in an Azure environment
Identity plane
Consent phishing and illicit OAuth grants, over-privileged app registrations and service principals, dynamic-group abuse, Conditional Access gaps, and stale app credentials.
Privilege escalation
Owner/Contributor sprawl, dangerous write permissions, custom-role misconfiguration, and paths to broader control.
Managed-identity abuse
Pivoting from a compromised VM or Function via its managed identity to reach other Azure resources, and metadata-service token theft.
Storage & secrets
Public Blob containers and SAS-token leakage, over-permissive Key Vault access, and secrets in App Service settings.
// 04 Common Azure findings
Over-privileged service principal
An application or service principal with far more directory or subscription access than it needs, giving an attacker who compromises it broad control.
Managed-identity pivot
A compromised VM or Function uses its managed identity to access Key Vault secrets or other resources it should not reach.
RBAC privilege escalation
Contributor-level access or a dangerous write permission that lets a user grant themselves higher privileges.
Public Blob container or leaked SAS
Sensitive data exposed through anonymous blob access or an over-scoped, leaked SAS token.

// 06 Frequently asked questions
Do I need to notify Microsoft?
No — not since June 2017. You may test your own resources under Microsoft's Unified Rules of Engagement with no form. Guides that say otherwise are out of date.
What does it cover?
Entra ID attacks, RBAC privilege escalation, managed-identity abuse, Blob and Key Vault exposure, and container breakout on App Service or Functions — your configuration and identities.
What's prohibited?
DDoS (entirely), accessing others' data or credentials, excessive-traffic fuzzing, phishing Microsoft staff, and exploiting a finding beyond initial identification on shared services.
Why the focus on identity?
Because Entra ID is Azure's control plane. The highest-impact attacks target identity, so that is where testing concentrates.
