Start by centralising identity and access control around a platform that can integrate with multiple systems, devices, and productivity suites. Standardise provisioning, deprovisioning, and policy enforcement across the environment, then phase out dependencies on tools that only work well inside one ecosystem. The goal is not to remove every vendor, but to preserve portability, consistency, and control.
Reduce lock-in by designing for portability, not for perfect vendor symmetry
Vendor lock-in in identity and device management usually starts when one product becomes the only place where core control decisions live. The practical answer is to keep the control plane as portable as possible, so identity, device posture, access policy, and lifecycle events can move across platforms without redesigning the whole operating model. That means preferring integrations and standards that survive vendor change, rather than features that only work end-to-end inside one suite.
Standardisation matters more than tool count. If provisioning, deprovisioning, policy evaluation, and device compliance are expressed consistently, organisations can swap or add vendors in stages instead of forcing a big-bang migration. That is also why lifecycle discipline around identity and access governance tends to reduce dependency pressure over time, even when the immediate problem is device management rather than a pure identity programme.
In practice, portability improves when teams separate authoritative identity records from vendor-specific enforcement layers. Use the central identity source, then let downstream tools consume it through APIs, federation, or policy hooks where possible. When a tool cannot express the same baseline controls outside its own ecosystem, treat that as a dependency to isolate, not as a default architecture to preserve.
Keep operations stable while you phase out proprietary dependencies
The safest way to reduce lock-in is to migrate control points incrementally. Organisations should stabilise the current operating model first, then replace narrow vendor dependencies one workflow at a time, starting with the highest-friction areas such as onboarding, offboarding, device registration, and access revocation. That sequencing reduces the chance that a platform change creates an identity outage or a wave of unmanaged devices.
A useful benchmark is whether the new process can support both day-to-day operations and rollback. If a control only works after a full ecosystem migration, it is not yet a safe replacement. This is why device management programmes should favour lifecycle management patterns that can be applied consistently across environments, instead of vendor-specific admin steps that are hard to reproduce elsewhere.
- Keep one authoritative source for identity and device state.
- Use common provisioning and deprovisioning workflows across all major platforms.
- Test policy portability before retiring the older tool.
- Retain a fallback path for critical administration during each migration wave.
Where organisations already have significant vendor dependence, the first win is often consistency, not replacement. A standard process that works everywhere is usually more valuable than a more advanced feature that only works in one stack.
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 CIS Controls v8, NIST CSF 2.0 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | 6 — Access Control Management | Portable identity/device control depends on consistent account and access administration. |
| 5 — Account Management | Reducing lock-in requires consistent provisioning and deprovisioning across tools. | |
| 4 — Secure Configuration of Enterprise Assets and Software | Device-management portability depends on repeatable configuration baselines across platforms. | |
| Recommendation — Standardise account and access administration so vendor changes do not break core control processes. Centralise account lifecycle workflows to keep provisioning and revocation independent of one vendor. Define baseline configurations that can be enforced across multiple device-management platforms. | ||
| NIST CSF 2.0 | PR.AC — Access Control | The question is about preserving portable access control while changing vendors. |
| PR.IP — Information Protection Processes and Procedures | Standardised identity and device workflows reduce operational dependence on one suite. | |
| GV.SC — Supply Chain Risk Management | Vendor lock-in is a supplier dependency problem with operational and resilience consequences. | |
| Recommendation — Implement portable access-control rules that can survive a platform switch. Document repeatable identity and device procedures so they remain consistent across vendors. Assess supplier dependency and contract leverage when selecting identity and device platforms. | ||
| NIST Zero Trust (SP 800-207) | AC-1 — Policy and Enforcement Separation | Portability improves when policy is separated from vendor-specific enforcement. |
| PL-1 — Policy | A common policy model helps preserve consistent control across multiple vendors. | |
| Recommendation — Separate policy definition from enforcement points so access decisions remain portable. Define one access and device policy model that downstream tools must implement. | ||
| OWASP Non-Human Identity Top 10 | NHI-01 — Secrets and Credential Management | Device and identity portability is weakened when credentials or lifecycle steps are trapped in one ecosystem. |
| Recommendation — Use portable secrets and credential handling so lifecycle operations are not vendor-bound. | ||
Practitioner Guidance
What to prioritise: Start with the identity and device actions that create the most operational risk if they are vendor-bound, especially joiner, mover, leaver flows and device compliance enforcement. Those are the places where lock-in becomes visible fastest, because a proprietary dependency can block access changes or delay revocation.
What to verify: Before trusting a portability plan, verify that the alternative platform can handle the same core decisions, not just import the same data. In particular, confirm that provisioning, policy enforcement, auditability, and emergency access paths still work when one vendor is removed from the stack.
Common mistake: Teams often keep the ecosystem closed because integration is convenient in the short term. That usually shifts cost into the future by making migration harder, increasing renewal leverage for the vendor, and tying operational resilience to one product roadmap.
Practitioner takeaway: The goal is not to eliminate vendor specialization, it is to ensure that no single vendor becomes the only place where identity or device control can be executed safely.
