TL;DR: Accurately identifying privileged access in Active Directory requires calculating effective permissions across every AD object, because delegated rights, group membership, and ownership changes can all create Domain Admin equivalent control, according to Paramount Defenses. For IAM and PAM teams, the key issue is that privilege assessment must follow actual object-effective access, not directory labels or group names.
NHIMG editorial — based on content published by Paramount Defenses: How to Correctly Assess Privileged Access in Active Directory
By the numbers:
- At 85% of all organizations worldwide, the most powerful privileged access as well as the vast majority of all powerful privileged access lie within millions of security permissions inside foundational Active Directory deployments worldwide.
Questions worth separating out
Q: How should security teams assess privileged access in Active Directory?
A: They should assess effective permissions on AD objects, not just group membership or role labels.
Q: Why do delegated permissions create hidden privilege in Active Directory?
A: Delegated permissions can grant broad control over users, computers, groups, and OUs even when the account is not in a top-tier admin group.
Q: What breaks when teams rely only on Domain Admins membership?
A: They miss accounts that can reach the same outcome through delegated rights, object ownership, or inherited permissions.
Practitioner guidance
- Assess effective permissions on high-value AD objects Calculate who can modify privileged groups, reset privileged passwords, change ownership, and alter ACLs on sensitive objects such as AdminSDHolder, domain controllers, and core OUs.
- Map domain admin equivalent tasks to named roles Break out administrative capabilities such as trust management, schema changes, secret replication, and GPO linking, then assign each capability to a responsible business or IT role.
- Review delegated access across the entire domain Scan for users who can create, manage, or delete users, computers, groups, and OUs, then confirm whether those rights still match current operational need.

Effective permissions are the only defensible measure of AD privilege. Active Directory governance fails when teams confuse declared rights with exercisable rights. ACLs, inheritance, ownership, and delegation can all combine into privilege that is not visible in a simple group review. The implication is that access discovery in AD has to move from role inventory to object-effective control.
A few things that frame the scale:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why access discovery gaps routinely outlast tooling upgrades.
A question worth separating out:
Q: Who should be accountable for privileged access changes in Active Directory?
A: Accountability should sit with the team that owns the object and the business process behind the entitlement, not only with the directory administrators. If a role can modify sensitive OUs, groups, or service accounts, that authority needs a named owner and a periodic review. Effective permissions without ownership accountability are hard to govern and easy to abuse.
