TL;DR: HIPAA access control requirements depend on verified, least-privilege decisions, continuous re-checks, and reviewable evidence rather than a zero-trust slogan, according to Zluri. Zero trust only becomes audit-relevant when access governance can prove who had PHI access, why it was granted, and when it was last reviewed.

Questions worth separating out
Q: How should security teams implement zero trust for PHI access in practice?
A: They should enforce access at the application level, not the network level, and require current role or attribute checks before each PHI request.
Q: Why do static access approvals fail for HIPAA environments?
A: Static approvals fail because PHI access changes as roles, vendors, and application footprints change.
Q: What breaks when access reviews are not tied to lifecycle events?
A: Reviews become a cleanup exercise instead of a governance control.
Practitioner guidance
- Classify PHI-handling applications first Inventory every application that stores, processes, or transmits PHI, then assign access controls by application instead of by broad network segment.
- Tie provisioning to lifecycle signals Connect joiner, mover, and leaver events to access changes so role changes, contractor exits, and department transfers update entitlements across every connected system.
- Run recurring PHI access reviews Pull current entitlements automatically, flag users whose role no longer justifies access, and document review outcomes with run logs for audit evidence.

Zero trust and HIPAA access controls: are your reviews enough?

Zero trust only satisfies HIPAA when it becomes a decisioning model, not a slogan. The article correctly shifts the conversation from network trust to access governance, which is where compliance evidence actually lives. HIPAA does not care whether a team uses the phrase zero trust; it cares whether PHI access is verified, scoped, and reviewable. The practitioner takeaway is that policy language without enforced access decisions is not an audit control.
A few things that frame the scale:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, according to The 2024 ESG Report: Managing Non-Human Identities.
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured.
A question worth separating out:
Q: Who is accountable when third-party PHI access is not removed on time?
A: The organisation remains accountable, even when the access belongs to a vendor or billing partner. HIPAA evidence must show that third-party accounts were scoped, reviewed, and removed when no longer needed. If offboarding is not enforced, the gap is a governance failure, not a vendor issue.
