TL;DR: Organizations often split digital access, physical access, and lifecycle governance across IAM, PACS, and PIAM, creating revocation gaps when employment or role changes are not propagated everywhere, according to AlertEnterprise. The real issue is not access control in isolation, but whether one identity lifecycle can reliably govern both doors and logins without manual lag.
NHIMG editorial — based on content published by AlertEnterprise: PIAM vs IAM vs PACS: Understanding the Difference Between Identity Management and Access Management Across Digital and Physical Security
By the numbers:
- NHIs outnumber human identities by 25x to 50x in modern enterprises.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
Questions worth separating out
A: They should treat the identity lifecycle as a single governance problem and map every joiner, mover, and leaver event to both IAM and PACS.
Q: Why do IAM and PACS create risk when they are not coordinated?
A: IAM controls logins, while PACS controls doors.
Q: What should security teams look for when evaluating PIAM maturity?
A: They should look for lifecycle closure, not feature lists.
Practitioner guidance
- Inventory cross-domain access paths Document where the same person can hold both badge access and application access, then identify which system is authoritative for each lifecycle event.
- Synchronise joiner-mover-leaver triggers Tie HR events to both IAM deprovisioning and PACS badge deactivation, and require exception tracking when one path completes before the other.
- Unify access certification evidence Make recertification reviewers see physical and digital entitlements in one workflow so badge access cannot be approved in isolation from system access.

Separate digital and physical access systems create an identity lifecycle blind spot. IAM and PACS each solve part of the problem, but neither on its own can prove that a terminated or transferred person has been fully removed from every access path. That leaves enterprises with a revocation gap that is operationally routine rather than exceptional. The practitioner conclusion is simple: lifecycle governance must be evaluated across domains, not inside a single platform boundary.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: Who is accountable when badge access remains active after offboarding?
A: Accountability should sit with the team that owns cross-domain identity governance, not with only IT or only facilities. If physical access lingers after offboarding, that is a lifecycle control failure. The corrective measure is to define one owner for access closure and one audit trail that covers both doors and logins.
