Azure AD/Entra ID Is Not Enough

Microsoft Entra ID – still known to many as Azure Active Directory – is already in use at most companies and reliably manages user accounts, groups, and login access to M365 services. But herein lies a common misconception: a directory service alone is not yet Identity & Access Management. IAM begins where the pure administration of accounts ends – at the question of who holds which permission and why, how long it remains valid, and who reviews it regularly.

The Gap Between Directory and Governance

Entra ID reliably answers the question “Who is this user?” But the truly business-critical questions are different: Why does an employee from sales have write access to a finance system? Was that permission ever revoked after the original project ended? Without structured access governance, permission structures grow uncontrolled over the years – a phenomenon known in practice as “permission creep,” which regularly produces unpleasant surprises during audits.

The Three Layers of a Complete IAM

A resilient IAM concept consists of considerably more than centralized user administration:

Identity Lifecycle Management – automated processes for onboarding, role changes, and offboarding (Joiner-Mover-Leaver), so permissions always match the current scope of responsibility
Least-Privilege Principle – access rights are granted according to the minimal-necessary principle and governed through role-based concepts (RBAC) rather than individual case-by-case grants
Access Reviews & Audit Readiness – regular, documented review of existing permissions that holds up under scrutiny from auditors and regulatory authorities when it matters

Privileged Access Management as a Special Risk Factor

Administrative accounts deserve special attention: they hold far-reaching rights and are therefore a preferred attack target. Privileged Access Management (PAM) ensures that highly privileged access is time-limited, logged, and activated only when actually needed – rather than existing permanently with full rights. Combined with multi-factor authentication, this significantly reduces the risk of compromised administrator accounts, one of the most common entry points in serious security incidents.

From Account to Compliance Foundation

IAM has long since ceased to be purely a security topic – it is also a regulatory one. Requirements such as NIS2 or industry-specific audit standards demand traceable proof of who could access which systems and when. A well-maintained IAM delivers exactly this proof – turning what was originally a technical necessity into a resilient governance instrument.

Conclusion

Entra ID is a solid foundation, but that is all it is: a foundation. Only well-designed processes for lifecycle management, least privilege, and regular access reviews turn a directory service into a functioning Identity & Access Management system. Companies that close this gap not only reduce their security risk but also lay the groundwork for regulatory proof obligations that will become noticeably stricter in 2026.
