Privileged access management in a hybrid Azure environment works only when every account that can bypass normal controls, a human admin, a service account, or a workload identity, loses standing access and gets it back just for the task at hand. Treat PAM as continuous enforcement, not a licence you renew once a year.
- Standing admin rights and static service account passwords are the two failures assessors flag most often in hybrid Azure estates.
- Azure AD Privileged Identity Management covers Entra roles well but has nothing to say about on-prem Active Directory or third-party applications.
- Workload identity federation removes the client secret that service accounts have depended on for years.
- Passing an audit on paper does not mean the control is enforced in the console.
Why privilege gets fluid once Azure AD meets on-prem AD
Hybrid identity is the source of most PAM gaps, not a side detail. An account can hold a role in Entra ID, sit in an on-prem AD group synced through Azure AD Connect, and carry local admin rights on a server, all at once, with no single console showing the full picture. Attackers do not need to compromise a domain admin directly. They compromise whichever hop has the weakest control and walk the rest of the path using legitimate credentials. Any PAM programme that only looks at one side of the sync, cloud or on-prem, is looking at half the attack surface.
Standing access is the default failure, not the exception
The starting point is not a tool purchase. It is removing permanent privilege. No human account should carry standing admin rights that exist whether or not anyone is using them that day. No service account should run with more scope than its one job requires. Just-in-time elevation, where a role is granted for a fixed window and expires automatically, closes the gap that standing access leaves open: an account that is privileged around the clock is an account an attacker can use around the clock, including the hours nobody is watching.
Azure's own Privileged Identity Management handles this well for Entra roles: time-bound activation, approval workflows, and access reviews are built in. The limitation is scope. PIM governs Entra ID and Azure resource roles. It does not touch on-prem AD, network devices, database accounts, or SaaS admin consoles. Enterprises running a genuinely hybrid estate end up needing PIM for the Azure side and a dedicated platform for everything PIM cannot reach, with the two talking to each other rather than running as separate, unrelated controls.
Service accounts are the accounts nobody owns
Service accounts fail differently to human accounts because nobody experiences the pain of a bad one. A person with excessive access eventually notices something is wrong, or a manager asks why they can see data they should not. A service account with global admin scope just sits there, doing its one job, until someone finds it during an audit or an attacker finds it first. The common pattern: an application was set up years ago, the person who configured it has moved on, the credential is hardcoded in a config file or a scheduled task, and nobody owns the decision to rotate it because nobody is sure what breaks if they do.
The fix is not exotic. Inventory every service account and workload identity across both directories. Assign an owner to each one, not a team, a named person or a role with continuity. Scope permissions to the specific resource the account touches rather than a broad admin role because that was the fastest way to make the error message go away. Rotate credentials on a schedule that does not depend on someone remembering.
Machine identities need identity verification, not just human MFA
Multi-factor authentication for staff stops the easy attacks: password spray, reused credentials, phishing that only captures a password. It does nothing for a service account authenticating with a static secret pulled from a configuration file, because there is no second factor for a script to satisfy. An attacker who extracts that secret authenticates exactly like the legitimate application does.
Workload identity federation removes the secret you cannot rotate
Azure AD supports workload identity federation, which lets an application or pipeline authenticate using a short-lived token issued by a trusted external identity provider instead of a stored client secret. There is no long-lived credential to leak, no secret sitting in a repository or a config file, and no rotation schedule to fall behind on because the token expires on its own. Where federation is not available, the fallback is managed identities for Azure resources, and conditional access policies that gate non-interactive sign-ins on device compliance or network location rather than leaving them unconditional. If a service account in the environment still authenticates with a password or an API key that has not changed in over a year, that is the account to deal with first.
What NESA assessors actually check
Regulatory frameworks relevant to UAE enterprises expect evidence of least privilege, logged privileged sessions, and a defined approval path for elevation. None of that is unusual or specific to the region. What is specific is how often the evidence exists on paper without existing in practice. A policy document describing least privilege is not the same as Azure RBAC actually enforcing it. A signed approval workflow is not the same as an admin being technically unable to escalate privilege without one.
A signed policy is not a control
Assessors who are doing their job will ask to see the control working, not just the document describing it: pull up an access review from the last quarter, show a session recording for a privileged login, demonstrate that a stale account was actually deprovisioned rather than just flagged. Passing a compliance audit against documented controls that are not enforced buys time, not security, and it tends to run out at the worst possible moment, during an incident, when the gap between what was written down and what was actually running becomes the story.
Entra PIM or a dedicated PAM platform: what actually decides it
This is a scope question, not a preference. If privileged access is confined to Azure AD and Azure resource roles, and the organisation is comfortable with native tooling and Microsoft's licensing model, PIM alone can carry the workload. Once privilege spans on-prem AD, network appliances, database accounts, or third-party SaaS admin consoles, a dedicated platform becomes necessary because PIM was never built to govern any of that. Session recording, password vaulting for legacy systems that cannot use modern authentication, and a single audit trail across cloud and on-prem are the capabilities that push mid-size and larger hybrid estates toward a platform like ARCON PAM or BeyondTrust sitting alongside Entra ID rather than instead of it. The licensing cost is real. So is the cost of an unowned service account with domain admin rights sitting undetected for years, which is the more common outcome when organisations skip the dedicated platform to save on licence fees.
Where to start this quarter
Run the audit before buying anything. Count the accounts with standing global admin or domain admin rights and be honest about the number. Inventory service accounts and workload identities across both directories and assign an owner to each. Check how many of those accounts still authenticate with a static password or a secret that has not rotated in the last year. Confirm that approval workflows for privilege elevation are actually enforced in the console, not only described in policy. Wherever the count of standing privileged accounts is higher than the number of people who legitimately need standing privileged access day to day, that gap is the PAM programme's first target, before any tool evaluation begins.
