Azure role sprawl is a quiet privilege risk. Siemserva audits subscription role definitions and assignments.
Azure subscriptions accumulate role definitions and RBAC assignments over time: owners who should be readers, standing privilege, and custom roles nobody remembers. Siemserva audits Azure subscription role definitions and assignments alongside your Entra ID identity posture.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Azure RBAC.
| What Azure RBAC does well | Where teams want more |
|---|---|
| Granular, scope-based role-based access control. | Role assignments sprawl and over-privilege creeps in. |
| Custom role definitions for least privilege. | Hard to see standing privilege and risky custom roles at a glance. |
| Management-group and subscription scoping. | No native posture ranking or compliance mapping. |
| Activity logging for changes. | Azure RBAC and Entra roles are easy to review in isolation, missing the full privilege picture. |
| Capability | Azure RBAC | Siemserva |
|---|---|---|
| Subscription role audit | Manual | Native |
| Over-privilege detection | Hard to see | Surfaced |
| Unified with Entra roles | No | Yes |
| Compliance mapping | No | MCSB, more |

Every finding, and the full graph behind it, is yours. Through the Senserva SDK and the Claude MCP you get complete access to the underlying Siemserva data, so you can query it, extend it, and build your own checks, reports, automation, and integrations on top. Nothing is locked away in a vendor cloud, and the data stays with you.
Siemserva does not just record pass or fail. It models your target environment, the identities, devices, applications, policies, and how they relate, as a queryable graph. That makes the data a foundation for new work: custom analysis, threat hunting, and automation, not a static checklist you read once and set aside.
Azure RBAC grants access by assigning a role (a set of permissions) to a principal (user, group, or service principal) at a scope (management group, subscription, resource group, or resource). Permissions inherit down the hierarchy, so an assignment high in the tree quietly applies to everything beneath it, which is both powerful and easy to over-grant.
Built-in roles like Owner and Contributor are convenient and over-used. Owner can grant access to others, an escalation path, and Contributor can change almost anything but manage access. Custom roles scoped to exactly what a workload needs are the least-privilege answer, yet many tenants accumulate broad standing assignments instead.
Privileged Identity Management extends to Azure resource roles, so even Owner and Contributor can be made eligible rather than standing, activated just in time with approval and MFA. Reviewing who holds privileged roles, where, and whether they need it permanently is the core of Azure access hygiene.
At scale, management groups, Azure Policy, and periodic access reviews keep RBAC from drifting. Classic administrators, orphaned service principal assignments, and guests with resource access are the usual findings that a structured review surfaces.
Yes, it audits Azure subscription roles and RBAC alongside Microsoft 365 and Entra ID, since privilege risk spans both.
