TL;DR: The principle of least privilege should apply across users, service accounts, devices, and processes to reduce over-provisioning, improve audit readiness, and limit breach impact, according to Zluri. The real governance issue is that access programmes still assume privilege can be set once and left alone, while also supporting just-in-time access and continuous review.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Understanding Principle of Least Privilege: In-Depth Guide”.
Key questions
Q: What breaks when SaaS access is granted once and never revisited?
A: Privilege creep turns the original approval into a standing exception, so the account can keep rights long after the business need has changed.
Q: Why do over-permissioned SaaS accounts increase exposure so quickly?
A: Because excessive roles and stale admin accounts turn a single compromise into broad access across files, integrations, and external sharing paths.
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
- Map every SaaS entitlement to a named business task Require every privilege to be justified by an owner, use case, and expiration condition so reviewers can compare granted access to actual need.
- Convert elevated access into JIT defaults Replace standing admin access with time-bound grants for short tasks, and make automatic revocation part of the approval path.
- Include service accounts in access reviews Review non-human accounts alongside employees, contractors, and vendors so dormant or over-permissioned machine access is not left out of governance.
Bottom line: Least privilege in SaaS fails when access governance stops at assignment and never manages entitlement drift, especially for service accounts and other non-human identities.

Least privilege in SaaS is a lifecycle problem, not a role-design problem: The article shows that access goes wrong when programmes stop at initial provisioning and do not govern entitlement drift. That is true for users and equally true for service accounts, devices, and processes. The practitioner conclusion is that privilege must be managed from grant through review to revocation, or the control only exists on paper.
A few things that frame the scale:
- More than 95% of infrastructure-as-a-service accounts use less than 3% of the entitlements they are granted, according to Gartner.
A question worth separating out:
Q: Should service accounts follow the same access rules as users?
A: Yes, because service accounts can expose SaaS data and administrative functions just as effectively as human users when they are over-privileged. The governance difference is ownership and lifecycle tracking, not whether the account deserves scrutiny. If the account can act, it needs scope, expiry, and review.
