They often focus on feature parity instead of governance redesign. If the new platform still reproduces static roles, long-lived permissions, and broad group membership, the organisation has only changed tooling, not reduced standing privilege or improved access accountability.
Why This Matters for Security Teams
Replacing one access platform with another is often treated as a product decision, but the real security question is whether the organisation changes how access is governed. If the migration preserves static roles, broad group membership, and long-lived entitlements, the attack surface remains largely intact. That is why guidance from the OWASP Non-Human Identity Top 10 matters here: tooling alone does not remove standing privilege.
This is especially visible in NHI-heavy environments, where access sprawl is already common. NHI Management Group’s Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, which explains why platform swaps can simply repackage the same risk under a different console. The security team’s mistake is assuming migration equals improvement. In practice, many teams discover the same overreach only after a secret leak, lateral movement, or failed offboarding has already exposed the weakness.
How It Works in Practice
A safer migration starts by redesigning the access model before moving users, services, or agents. That means identifying what each identity actually does, what it should do, and what must be temporary. For human access, current guidance from NIST SP 800-53 Rev. 5 Security and Privacy Controls still points teams toward least privilege, access reviews, and separation of duties. For NHIs, that same logic has to be applied more aggressively because credentials are often embedded in workflows, not held by a person.
Good migration practice usually includes:
- Inventorying every current entitlement, service account, API key, and automation token before cutover.
- Mapping legacy roles to business functions, not to platform defaults.
- Replacing broad group membership with task-scoped access where possible.
- Issuing short-lived secrets or tokens instead of copying long-lived credentials into the new system.
- Defining revocation and offboarding steps in the migration plan, not as a post-launch cleanup item.
NHIMG’s Ultimate Guide to NHIs — Key Challenges and Risks highlights how often secrets remain outside proper management and how rarely revocation is operationalised. That is the practical lesson: migration should reduce the number of identities with durable access, not just move them into a different control plane. These controls tend to break down when legacy applications require shared credentials because teams then recreate broad access patterns to keep the cutover moving.
Common Variations and Edge Cases
Tighter access design often increases migration effort, requiring organisations to balance risk reduction against delivery speed and application compatibility. That tradeoff becomes sharp in environments with legacy systems, vendor-managed integrations, and shared admin accounts, where a clean one-to-one replacement is not always possible.
There is no universal standard for every migration pattern, but current guidance suggests treating exceptions as temporary and documented. If a platform cannot support per-task access, just-in-time provisioning, or meaningful auditability, then the problem is not only the migration design but also the target platform’s governance fit. This is where many teams overvalue feature parity and undervalue operational control.
The same issue appears in third-party access. The NHI security research in The State of Non-Human Identity Security shows that 85% of organisations lack full visibility into third-party vendors connected via OAuth apps. If the new platform still depends on hidden integrations or inherited trust chains, the migration can expand blind spots instead of closing them. In short, a platform swap fails when it preserves the old trust model and only changes the interface.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST SP 800-63, NIST Zero Trust (SP 800-207) and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Platform swaps often preserve excessive standing access and weak identity governance. |
| NIST CSF 2.0 | PR.AA | Identity and access management controls apply directly to migration redesign. |
| NIST SP 800-63 | Digital identity assurance helps prevent unsafe reuse of legacy access patterns. | |
| NIST Zero Trust (SP 800-207) | 4.1 | Zero Trust requires continuous verification rather than inherited trust from prior tooling. |
| NIST AI RMF | GOVERN | Governance is the key failure mode when organisations change tools without changing control intent. |
Treat the migration as a trust redesign exercise and re-evaluate every entitlement at request time.
