TL;DR: A single compromised Active Directory privileged account, including delegated privileges outside default admin groups, can give attackers command and control over systems, data, and authentication paths, according to Paramount Defenses. The core issue is that access review models often miss effective permissions, so risk remains hidden until compromise occurs.
NHIMG editorial — based on content published by Paramount Defenses: Impact of Privileged User Compromise
By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities - 46% confirmed, 26% suspected.
Questions worth separating out
Q: What breaks when delegated Active Directory permissions are not treated as privileged?
A: You lose sight of the real control boundary.
Q: Why do delegated permissions in Active Directory increase breach impact so quickly?
A: Because a single permission can cascade through inheritance, group membership, policy linkage, and authentication changes.
Q: How do security teams know whether a directory account is effectively privileged?
A: They should evaluate what the account can change, not just what role name it carries.
Practitioner guidance
- Inventory effective permissions, not just admin group membership Extract and review who can reset passwords, change group membership, modify OU permissions, alter AdminSDHolder, and change authentication policy across the directory.
- Classify delegated rights as privileged when they can change the control plane Treat rights that can alter inheritance, policy linkage, or privileged account configuration as high-risk PAM scope even if the account is not in Domain Admins.
- Protect authentication-policy changes with separate approval paths Require stronger controls for actions that can disable smartcards, weaken authentication, or reset executive and administrative passwords.
What's in the full article
Paramount Defenses' full article covers the operational detail this post intentionally leaves for the source:
- The specific Active Directory delegation patterns that can silently create privileged access across users, groups, and computers
- The control-by-control impact examples for AdminSDHolder, OU permissions, GPO linkage, password reset rights, and smartcard downgrade paths
- The article's detailed explanation of how effective permissions should be identified across directory objects and why default admin groups are not enough
- The full list of top administrative delegations that often sit outside traditional privileged access inventories

Active Directory delegated privilege: what IAM teams are missing?

Effective permissions are the real privilege boundary in Active Directory. The article correctly exposes the weakness in group-based thinking: many organisations still model privilege as membership in a small set of default admin groups, while the actual control surface is defined by object-level delegation. That assumption fails because directory power is distributed through permissions, not labels. The implication is that IAM and PAM programmes must treat effective permissions as the authoritative source of privilege truth.
A few things that frame the scale:
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, according to The State of Non-Human Identity Security.
- A separate finding from the same research says 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, with 38% reporting no or low visibility and 47% reporting only partial visibility.
A question worth separating out:
Q: Who is accountable when a delegated admin right is abused in Active Directory?
A: Accountability sits with the teams that granted, approved, and failed to recertify the delegated permission, not only with the account owner. The governance question is whether the privilege was ever classified as high-impact and whether its downstream effect was understood before approval.
