TL;DR: Active Directory contains the privilege-bearing accounts, groups, and delegated permissions that can expose an entire domain, while local admin compromise is usually limited to a single machine, according to Paramount Defenses. The practical issue is not just finding admins but understanding effective access, because excessive permissions create hidden escalation paths that conventional reviews often miss.
Editorial analysis by NHI Mgmt Group, based on content published by Paramount Defenses: “Privileged Access Attack Surface”.
By the numbers:
- At 85% of all organizations worldwide, the privileged user and employee accounts, computer accounts and security groups that form the security building blocks reside inside Active Directory.
Key questions
Q: What breaks when organisations only review local administrator accounts in Active Directory?
A: They miss the permissions that actually govern domain-wide reach.
Q: Why do delegated Active Directory rights create more risk than they appear to on paper?
A: Because small-looking rights can translate into broad control once inheritance and object relationships are resolved.
Q: How do security teams know whether privileged access in Active Directory is actually under control?
A: They should look for reduced over-permissioning, fewer shadow accounts, and faster detection of abnormal permission changes.
Practitioner guidance
- Map effective access on privileged AD objects Resolve who can actually reset passwords, modify memberships, take ownership or change permissions on privileged accounts, groups, OUs and AdminSDHolder, then prioritise those paths for review.
- Reclassify delegated rights as privilege Treat Reset Password, Write-Property Member and Modify Permissions on directory objects as privileged capabilities, even when they are not assigned to obvious admin roles.
- Review high-value group membership controls Inspect domain security groups that provision broad access, because membership changes there can instantly expand reach across many IT assets.
Bottom line: The main risk is not local administrator compromise but the much wider reach of Active Directory permissions, delegated rights and privileged objects.

Active Directory privilege exposure is really an effective-access problem, not a local-admin problem. The article shows that the highest-risk rights in AD sit in accounts, groups and objects that can rewrite authorization across the domain. Local admin scope ends at the host, but AD permissions can cascade through inheritance and delegation. The practical conclusion is that identity governance must model what access can do, not just what role name it carries.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should IAM and PAM teams prioritise first in Active Directory privilege reviews?
A: Start with the control points that can rewrite access for many others, especially privileged groups, AdminSDHolder, the domain root and large OUs. Those objects can turn ordinary permissions into enterprise-wide privilege. Prioritise them before low-impact local admin accounts, because they determine the blast radius of compromise.
