Answers to the questions practitioners most commonly ask about Push Provisioning.
Is push provisioning in IAM just another name for SCIM?
Not exactly. SCIM (System for Cross-domain Identity Management) is a specific standard that defines a REST/JSON protocol and schema for identity lifecycle operations. Push provisioning in the IAM sense describes the general pattern where an authoritative source (typically an identity provider or IGA platform) initiates and sends identity data to downstream target systems, rather than having each target pull or poll for changes. SCIM is one common way to implement push provisioning, but push provisioning can also be realized through vendor-specific connectors, proprietary APIs, or directory synchronization. Treating the two as synonyms conflates a general provisioning pattern with one particular standard that implements it.
Does push provisioning handle authentication or grant users access at runtime?
No. Push provisioning is an identity governance and administration (IGA) lifecycle concern: it creates, updates, deactivates, or deletes accounts and attributes in target systems ahead of or in response to lifecycle events. It does not authenticate a user and does not make runtime authorization decisions. When a provisioned user later signs in, authentication is handled separately (for example via SAML 2.0, OpenID Connect, or the target's own credential mechanism), and authorization is evaluated at access time. Provisioning may populate the roles, group memberships, or attributes that a downstream access decision later relies on, but the enforcement step is distinct from the provisioning step.
How do you decide between push provisioning and pull-based (or just-in-time) provisioning?
The choice typically depends on when accounts must exist and how targets consume identity data. Push provisioning is often preferred when accounts must be present before first login, when deprovisioning must happen promptly for security or compliance reasons, or when the target cannot create accounts on the fly. Just-in-time (JIT) provisioning, by contrast, commonly creates or updates the account during an authentication flow (for example from SAML or OIDC assertions) and can reduce dormant accounts, but it generally cannot remove access on its own and does not act until the user attempts to sign in. Many deployments combine both: push for creation and deprovisioning, JIT for attribute updates at login. The right balance depends on the target's capabilities and your governance requirements.
How is deprovisioning typically handled in a push model?
In most push deployments, a lifecycle event in the authoritative source (such as termination or role change) triggers a provisioning operation against the target. Depending on the target and configuration, this may disable, delete, or modify the account. Behavior varies significantly: some targets support soft-disable, some only support deletion, and some retain data after account removal. Because deprovisioning is often the highest-risk operation from a security and compliance standpoint, teams commonly favor deactivation over hard deletion where reversibility and audit retention matter, and they should verify how each connector maps a deprovisioning action to the target's native semantics.
What should you monitor to ensure push provisioning stays reliable?
Common signals include provisioning job success and failure rates, latency between a source event and the target update, reconciliation results that detect drift between the authoritative source and target state, and error patterns from individual connectors. Because push operations can fail silently at the target (for example due to schema mismatches, rate limits, or permission changes), periodic reconciliation or audit comparison is typically recommended rather than relying solely on the assumption that a sent operation succeeded. Logging each provisioning action also supports access certification and audit evidence.
How do access reviews and segregation of duties relate to push provisioning?
Push provisioning is the mechanism that applies entitlements to target systems, while access reviews (certifications) and segregation-of-duties (SoD) checks are governance controls that determine whether those entitlements should exist. In a well-designed IGA program, SoD policies are typically evaluated before provisioning is executed, so conflicting access is prevented or flagged rather than pushed. Access reviews then periodically confirm that provisioned access remains appropriate, and revocation decisions from a review can trigger downstream deprovisioning through the same push channels. Keeping these as distinct steps, policy evaluation, provisioning, and certification, helps maintain a clear audit trail.
