TL;DR: Privilege escalation remains the critical second step after credential abuse, with attackers using misconfigurations, over-permissioned service accounts, delegated trust, and open privileged protocols to turn one foothold into broad control, according to Zero Networks. The governance gap is not detection alone but architectural friction that limits where valid credentials can go.
NHIMG editorial — based on content published by Zero Networks: Stopping Privilege Escalation: How to Neutralize Stolen Credential Threats
By the numbers:
- 71% of threat activity flows through just four protocols.
- 2.6% of workload identity permissions are actually used.
- 51% of workload identities are completely inactive.
Questions worth separating out
Q: What breaks when stolen credentials can still reach privileged protocols?
A: When stolen credentials can still reach privileged protocols, authentication becomes a gateway to escalation rather than a boundary.
Q: Why do service accounts make privilege escalation harder to control?
A: Service accounts make privilege escalation harder to control because they are often overprivileged, under-monitored, and deeply embedded in operational traffic.
Q: How do security teams know whether privilege escalation controls are working?
A: They should test whether a valid credential can still reach sensitive assets, privileged protocols, or admin functions without additional verification.
Practitioner guidance
- Map privileged reach, not just privileged accounts Document which identities can reach admin protocols, management ports, and sensitive systems after authentication.
- Remove unnecessary service account trust Review service accounts, delegated permissions, and inherited roles for operational scope that exceeds the task they actually perform.
- Enforce just-in-time verification on admin paths Require step-up verification at the moment privileged access is requested, especially for RDP, WinRM, SMB, and RPC.
What's in the full article
Zero Networks' full article covers the operational detail this post intentionally leaves for the source:
- A practical breakdown of the privilege-escalation techniques the vendor maps to real environments.
- Identity-based microsegmentation examples that show how reachability can be constrained at the network layer.
- The vendor's explanation of just-in-time MFA on privileged protocols and how it changes access flow.
- Implementation framing for automating policy creation and enforcement across dynamic enterprise environments.

Privilege escalation is the point where identity governance stops being an access problem and becomes a containment problem. Once stolen credentials can reach privileged protocols, service accounts, or delegated trust paths, the issue is no longer just authentication. The environment has already accepted a trust model that lets one identity become many actions. Practitioners should treat escalation paths as part of identity architecture, not as an after-the-fact detection problem.
A few things that frame the scale:
- 71% of threat activity flows through just four protocols, according to the Ultimate Guide to NHIs , Key Challenges and Risks.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, according to The State of Non-Human Identity Security.
A question worth separating out:
Q: Who is accountable when identity and network controls do not line up?
A: Accountability usually spans IAM, PAM, infrastructure, and network teams because the failure sits between those domains. If identity grants access but the network still allows broad internal reach, no single control owns the full risk. Governance should assign responsibility for reachable privilege, not just for credential issuance or policy definition.
