TL;DR: Least privilege only works when every identity, human or machine, is constrained to the task it actually performs, and Securden’s analysis shows valid credentials and standing access now drive most breaches, not broken software. The real governance problem is that enterprise IAM still assumes access can be granted broadly and reviewed later, even as AI and NHI behaviour demands tighter, runtime-scoped control.
NHIMG editorial — based on content published by Securden: least privilege across human, machine, and AI identities
By the numbers:
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption.
Questions worth separating out
Q: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation.
Q: Why do over-privileged identities increase breach impact?
A: Over-privileged identities expand the damage a stolen credential can do because the attacker inherits more pathways into sensitive systems.
Q: How do security teams know whether least privilege is actually working?
A: Least privilege is working when identities have narrowly scoped permissions, unused credentials are removed or quarantined, and repeated access reviews consistently shrink entitlements.
Practitioner guidance
- Inventory all privileged identities across human, machine, and cloud estates Build one inventory that includes service accounts, API keys, certificates, SSH keys, admin users, and cloud entitlements so standing access is visible before policy is changed.
- Replace hardcoded secrets with runtime retrieval Move credentials out of code and CI/CD pipelines, then force applications to retrieve them at execution time through controlled secret access paths.
- Time-box elevated access by default Use just-in-time elevation for administrative work and make approval-based access the normal pattern instead of leaving privileged roles permanently active.
What's in the full article
Securden's full article covers the operational detail this post intentionally leaves for the source:
- Step-by-step examples of how least privilege is applied across human, service, and cloud identities
- Operational descriptions of PAM, endpoint privilege management, secrets management, and CIEM-style controls in one platform
- Specific examples of session recording, just-in-time elevation, and time-bound access in privileged workflows
- A comparison table showing how each capability maps to the access problems it is meant to reduce

Least privilege is now an NHI governance discipline, not just an IAM slogan. The article is correct that the principle applies to every identity type, but the operational challenge has shifted to machine and AI identities that scale faster than human review cycles. Service accounts, tokens, and API keys create more standing access than most organisations can see. The practitioner conclusion is that least privilege must be enforced as an identity lifecycle control, not a one-time permission design exercise.
A few things that frame the scale:
- The ratio of machine identities to human identities now exceeds 100:1 in enterprise environments, according to Ultimate Guide to NHIs , Why NHI Security Matters Now.
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption, according to The 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between just-in-time access and standing privilege?
A: Just-in-time access grants privilege only for a defined task window, while standing privilege remains active until someone removes it. JIT reduces exposure by shrinking the time an identity can be abused, but standing privilege creates a constant attack surface. For NHI programs, the difference is often the difference between contained risk and persistent exposure.
