TL;DR: Centralized access management concentrates policy, visibility, and auditability into one control plane, while decentralized models spread trust and responsibility across multiple issuers and wallets, according to Zluri’s analysis. The real governance question is not convenience versus flexibility, but how much fragmentation your access programme can absorb before oversight and compliance break down.

Questions worth separating out
Q: How should security teams choose between centralized and decentralized access management?
A: Security teams should choose the model that best matches their governance burden.
Q: When does decentralized access management become a governance risk?
A: It becomes a governance risk when local control points start creating different rules, different logs, and different revocation speeds.
Q: What do teams get wrong about centralized access management?
A: Teams often assume centralization automatically means strong control.
Practitioner guidance
- Map control ownership before choosing the model Document which team owns policy, logging, certification, and emergency revocation in a centralized or decentralized design.
- Standardise minimum governance controls across every issuer Define the same baseline for authentication assurance, access logging, and review evidence even when local teams manage their own access decisions.
- Test offboarding and revocation across the full access chain Simulate leaver, mover, and role-change scenarios to see how quickly credentials disappear from every control point.

- A side-by-side walkthrough of centralized and decentralized access management models at the implementation level.
- Detailed discussion of how SSO, wallets, issuers, and verifiers affect real-world access decisions.
- A deeper look at the cost, user experience, and compliance trade-offs teams should evaluate before standardising a model.

Centralized access management wins when the problem is control consistency, not because it is simpler. A single policy plane makes review, auditing, and response materially easier when the enterprise needs one answer to who has access to what. That same design also creates a single operational dependency, so resilience and administrative discipline matter as much as policy design. Practitioners should judge it as a governance architecture, not as a convenience feature.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to Ultimate Guide to NHIs.
- 79% of organisations have experienced secrets leaks, and 77% of those incidents caused tangible damage.
A question worth separating out:
Q: Who should be accountable for access reviews in a fragmented access model?
A: Accountability should sit with the team that can prove both policy ownership and evidence quality. If access decisions are distributed, each issuer or local owner must still produce review records that align to a shared enterprise standard. Otherwise the review process becomes ceremonial instead of governable.
