TL;DR: IAM security platforms are trying to enforce least privilege at scale by combining entitlement discovery, JIT elevation, and continuous rightsizing across human and non-human identities, according to Opti. The hard problem is not policy intent but keeping access aligned as sprawl, standing privilege, and machine identities outpace manual governance.
Editorial analysis by NHI Mgmt Group, based on content published by Opti: “Best IAM Security Systems for Enforcing Least Privilege: Top 8 in 2026”.
Key questions
A: Security teams should route SaaS access through a controlled gateway and apply identity and device based policy before traffic reaches the application.
Q: When does standing privilege become unacceptable in modern IAM programmes?
A: Standing privilege becomes unacceptable when the identity can act faster than your review cycle, especially for workloads and AI agents that move across systems autonomously.
Q: How should organisations govern service accounts alongside workforce access?
A: Organisations should govern service accounts with the same identity governance model used for workforce access, but with tighter ownership, purpose and secret controls.
Practitioner guidance
- Implement continuous entitlement discovery Build a live inventory of users, service accounts, workloads, APIs, and applications, then reconcile effective permissions against business need on an ongoing basis.
- Move high-risk access to just-in-time elevation Reserve persistent privileged access for the smallest possible set of break-glass scenarios and make routine admin access temporary and task-scoped.
- Right-size machine identity permissions Review service accounts and other non-human identities for unused entitlements, long-lived access, and permissions that were added for integrations that no longer exist.
Bottom line: Least privilege breaks down when organisations cannot continuously reconcile assigned permissions with actual business need across humans and machines.

Least privilege has become an entitlement management problem, not a role design problem: The practical bottleneck is no longer whether organisations can define access principles. It is whether they can continuously reconcile the permissions that exist in cloud, SaaS, and infrastructure systems against the permissions that should still exist. That makes effective-permissions visibility the foundation for any credible least-privilege programme, especially when access is distributed across multiple platforms.
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.
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What is the difference between RBAC and ABAC in SaaS access control?
A: RBAC assigns access based on job role, while ABAC applies context such as device posture, location, time, or risk signals. In SaaS, RBAC is useful for baseline assignment, but ABAC is better for step-up decisions and sensitive actions. Most mature programmes need both, because static role mapping alone cannot handle dynamic SaaS risk.
