Orphaned accounts in hybrid identity: what governance teams miss

TL;DR: Orphaned accounts are inactive identities that still retain valid access across AD and SaaS, creating hidden lateral-movement and compliance risk as HR, IT, and cloud directories drift apart, according to SecurEnds. The governance problem is not just discovery, but the failure to keep deprovisioning, access reviews, and ownership aligned across the full identity lifecycle.

NHIMG editorial — based on content published by SecurEnds: orphaned account detection and cleanup in hybrid environments

By the numbers:

• 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.

Questions worth separating out

Q: What breaks when orphaned accounts are not removed after offboarding?

A: When orphaned accounts are not removed, the organisation loses the link between ownership and access.

Q: Why do orphaned accounts create both security and compliance risk?

A: They create security risk because dormant access remains available to attackers and may still include old privileges.

Q: How can security teams measure whether orphaned account cleanup is working?

A: Measure more than discovery counts.

Practitioner guidance

• Reconcile HR and directory state continuously Compare HR termination and role-change events against AD, Azure AD, and SaaS identity stores so orphaned identities are removed as soon as business ownership ends.
• Prioritise dormant accounts with retained privilege Review inactive accounts for group membership, admin roles, shared credentials, and application access before you classify them as low risk.
• Automate leaver-based deprovisioning workflows Use IGA workflow triggers to remove access, notify system owners, and retain audit evidence whenever an identity no longer matches an active worker or approved contractor record.
