Why do ITOM platforms create identity governance risk when they centralise workflows?

Centralisation can make identity governance stronger only if the entitlement model is accurate and the offboarding logic is complete. Otherwise, one platform becomes the fastest way to spread stale access across apps, teams, and service relationships. The risk is not centralisation itself, but unchecked propagation of access decisions.

Why Centralised ITOM Workflows Increase Identity Risk

ITOM platforms often sit at the center of provisioning, ticketing, orchestration, and service mapping, which makes them powerful and dangerous at the same time. When one workflow engine can create accounts, assign roles, open integrations, and trigger downstream actions, any mistake in the entitlement model becomes system-wide. The problem is usually not the platform itself, but the assumption that a central workflow is automatically a governed workflow.

Identity governance depends on accurate ownership, approved access paths, and complete revocation logic. If those controls are weak, the platform amplifies bad decisions faster than a manual process would. That is why NHI Mgmt Group’s guidance on the Ultimate Guide to NHIs emphasizes lifecycle discipline, not just inventory. In practice, centralised ITOM can also create hidden coupling between service accounts, API keys, and delegated admin paths, making revocation harder than creation. Current guidance from the NIST Cybersecurity Framework 2.0 still points practitioners toward governance, least privilege, and continuous control validation rather than trust in workflow convenience. In practice, many security teams discover stale entitlements only after a workflow has already propagated them into several applications and service relationships.

How the Risk Spreads Across Apps, Teams, and Service Relationships

Centralisation creates identity governance risk when the platform becomes the default source of truth for access, yet does not also become the source of truth for deprovisioning, exception handling, and periodic review. A single workflow may provision a user, service account, or integration token into multiple systems, but the reverse path is often incomplete. That leaves orphaned access behind when a role changes, a service is retired, or a ticket is closed without full cleanup.

In mature environments, the safest pattern is to separate orchestration from authority. The ITOM platform should request action, but policy should decide whether that action is allowed at runtime. That means integrating with identity governance, PAM, secrets management, and workflow approvals instead of hard-coding access logic into tickets. The Top 10 NHI Issues highlights why excessive privilege and weak rotation are so damaging, especially when automation distributes credentials faster than humans can review them. The NIST Cybersecurity Framework 2.0 supports continuous monitoring, but it does not replace accurate workflow design.

• Inventory every identity the platform can create, modify, or deactivate.
• Define who approves each entitlement and who owns revocation.
• Use short-lived access where possible instead of persistent credentials.
• Test offboarding paths, not just provisioning paths.
• Log downstream propagation so hidden access can be found quickly.

NHIMG research shows that only 20% of organisations have formal processes for offboarding and revoking API keys, which is exactly where centralised workflows tend to fail. These controls tend to break down when the platform is allowed to provision across legacy apps that lack reliable deprovisioning APIs because revocation becomes manual and incomplete.

Where the Governance Model Breaks Down in Real Environments

Tighter centralisation often improves consistency, but it also increases blast radius, requiring organisations to balance operational speed against control precision. The hardest edge cases are hybrid estates, inherited service accounts, and platforms that manage both human and non-human identities through the same approval path. Current guidance suggests this should be treated as a governance design problem, not a tooling preference.

There is no universal standard for every ITOM architecture yet, but best practice is evolving around separation of duties, explicit lifecycle ownership, and control-point validation. Where an ITOM tool can trigger access in multiple systems, identity teams should insist on policy checks at the point of action, not only at the point of request. The Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is useful here because it frames provisioning, rotation, review, and offboarding as one connected lifecycle. For organisations with complex service catalogs, centralisation breaks down when ownership is fragmented across application teams, because nobody can prove that every downstream entitlement is still justified after the original workflow completes.
