TL;DR: As organisations scale across cloud, SaaS, and hybrid environments, role engineering becomes harder to sustain and poorly designed RBAC creates overprivilege, role explosion, and SoD risk, according to SecurEnds. The governance problem is no longer access assignment alone, but keeping roles clean enough to remain reviewable, auditable, and least-privileged over time.
NHIMG editorial — based on content published by SecurEnds: Role design for least privilege is breaking at enterprise scale
By the numbers:
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems, according to The 2026 Infrastructure Identity Survey.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
Questions worth separating out
Q: How should security teams design least privilege roles without creating role explosion?
A: Start with common job functions, then map only the entitlements that are truly shared across those functions.
Q: Why do poorly designed roles create segregation-of-duties risk?
A: Because the conflict is often built into the role itself.
Q: What breaks when organisations let role explosion continue unchecked?
A: Governance breaks first.
Practitioner guidance
- Inventory direct entitlements before redesigning roles Collect current assignments across SaaS, ERP, cloud, databases, and privileged systems so you can see where users still hold direct permissions outside the role model.
- Block toxic combinations during role approval Add segregation-of-duties checks to the role design workflow so create-and-approve, provision-and-certify, and similar conflicts are rejected before deployment.
- Retire legacy roles on a defined schedule Set ownership, review cadence, and retirement criteria for every role so outdated structures do not remain active after reorganisations, migrations, or process changes.

Least privilege role design is now a lifecycle problem, not a one-time modelling exercise. The article correctly treats role engineering as a structured governance discipline, but the real failure mode is accumulation over time: exceptions, legacy roles, and duplicate entitlements eventually outgrow the original design. That is why access review quality depends on role quality. If the catalogue is noisy, certification becomes theatre instead of control. The practitioner conclusion is that role governance must be managed as a living identity asset.
A few things that frame the scale:
- 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.
- 59% of infrastructure leaders cite "confidently wrong" AI configuration as their top fear, according to The 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do you know if an RBAC role model is actually working?
A: Look for fewer direct entitlements, lower role exception counts, cleaner certification outcomes, and fewer obsolete or duplicate roles. If reviewers still need to interpret every assignment manually, the model is too complex. A working role model should make access easier to explain, not harder.
