What this product actually is

Microsoft Entra ID is workforce identity when you’re already standardized on Microsoft 365/Azure. Great for conditional access and governance; heavier for pure customer CIAM flows.

Pricing behavior (not a price list)

These points describe when users typically pay more, what actions trigger upgrades, and the mechanics of how costs escalate.

Actions that trigger upgrades

  • Need stronger conditional access policies (device/risk controls)
  • Need identity governance (reviews, approvals, lifecycle) at scale
  • Need advanced security reporting and incident response capabilities
  • Need hybrid identity integration and consistent access policies
  • Need enterprise support/SLA for identity as core infrastructure

When costs usually spike

  • Hybrid directory setups add ongoing operational overhead
  • Governance features require process ownership, not just licensing
  • Large tenants need strict admin role design to avoid policy drift
  • Cross-tenant complexity appears quickly in M&A and multi-org setups
  • Customer identity use cases can expand scope beyond Entra’s defaults

Plans and variants (structural only)

Grouped by type to show structure, not to rank or recommend specific SKUs.

Plans

  • Core - Included/tenant-based - Baseline directory identity (varies by Microsoft licensing)
  • Security - Per-user add-ons - Conditional access and advanced controls (see pricing page)
  • Governance - Per-user add-ons - Reviews, lifecycle, and governance workflows (see pricing page)

Costs & limitations

Common limits

  • Microsoft-centric: non-Microsoft stacks can feel second-class
  • Complexity increases across tenants, subscriptions, and governance needs
  • Some advanced identity governance features require upgrades
  • Developer-first CIAM flows may be heavier than Auth0/Clerk/Firebase
  • Feature sprawl can make “what plan includes what” hard to manage
  • Cross-tenant and hybrid directory scenarios add operational work

What breaks first

  • Admin complexity as policies and roles proliferate
  • B2B/partner access governance if ownership isn’t clear
  • Migration complexity when consolidating multiple tenants
  • Developer velocity if customer auth is forced into workforce patterns
  • Security posture if conditional access is inconsistently applied

Fit assessment

Good fit if…

  • Organizations standardized on Microsoft 365 and Azure
  • Workforce identity with conditional access and centralized governance
  • IT/security teams already operating Microsoft security tooling
  • B2B partner access and collaboration scenarios
  • Teams that want to avoid introducing another IdP vendor

Poor fit if…

  • You want a developer-first CIAM platform for customer login flows
  • Your stack is primarily non-Microsoft and you need neutral integrations
  • You need maximum customization over auth UX and flows
  • You want usage-based MAU pricing for customer auth
  • You need simple auth for a small app without enterprise governance

Trade-offs

Every design choice has a cost. Here are the explicit trade-offs:

  • Ecosystem integration → Strongest for Microsoft-heavy orgs
  • Enterprise governance → More complexity than developer-first auth layers
  • Default availability → May not match product-team CIAM needs
  • Broad feature set → Harder to reason about entitlements and rollout
  • Centralized identity → Requires operational discipline

Common alternatives people evaluate next

These are common “next shortlists” — same tier, step-down, step-sideways, or step-up — with a quick reason why.

  1. Okta — Same tier / workforce IAM
    Common alternative when comparing enterprise-grade workforce SSO/MFA and governance depth.
  2. OneLogin — Same tier / workforce IAM
    Evaluated as a workforce SSO/MFA alternative for mixed environments.
  3. Auth0 — Step-sideways / CIAM
    Shortlisted when the primary need is customer identity flows rather than workforce directory governance.
