Okta vs. Microsoft Entra ID: Running Okta Alongside Microsoft 365

If your company runs Microsoft 365, you already have Entra ID. So why do thousands of enterprise organizations still deploy Okta alongside it? This guide breaks down the differences, the gaps, and exactly how to architect a co-existence strategy that wins.

Written for IT Directors, Security Leaders, and CISOs managing mixed SaaS environments who need a vendor-neutral answer — not a sales pitch.

The Short Answer

Stop asking “which one” — start asking “for what”

Microsoft Entra ID is bundled into your M365 license and handles authentication for Microsoft services beautifully. But the moment you need to manage identity across multi-cloud, non-Microsoft SaaS apps, partner portals, or customer-facing systems, Entra ID shows its limits. Okta was purpose-built for exactly that scenario. The best enterprise architectures use Entra ID as the authoritative user directory and Okta as the federation and orchestration layer — giving you the best of both platforms without duplication or risk.

Identity Platform

Okta

Microsoft

Entra ID

Verdict

Bottom Line

Cost

Additional license fee on top of M365. Okta starts ~$2/user/mo; advanced governance ~$5+.

Extra cost

Cost

Included in M365 E3/E5. Entra ID P1 included with Business Premium. Zero incremental cost for basic use.

Included

Verdict

Entra wins on paper. But factor in Okta's admin efficiency and non-Microsoft app coverage — the ROI often balances out at scale.

App Coverage

7,000+ pre-built integrations in the Okta Integration Network. Custom SAML/OIDC in minutes. Vendor-neutral by design.

Best in class

App Coverage

Excellent for Microsoft apps. ~3,000 apps via the App Gallery. Non-Microsoft coverage is noticeably thinner.

Microsoft-first

Verdict

If your stack is 80%+ Microsoft, Entra handles it. Mixed SaaS environments — Okta wins clearly.

MFA & Adaptive Access

Okta's Adaptive MFA uses contextual signals (device, location, behavior) across any app. Excellent policy granularity.

Highly flexible

MFA & Adaptive Access

Microsoft Conditional Access is powerful and deeply integrated with Defender, Intune, and M365 risk signals. Requires P1/P2.

Deep MS integration

Verdict

Both are strong. Co-existence architectures often let Entra CA govern Microsoft workloads while Okta governs everything else.

Lifecycle Management

Okta Lifecycle Management auto-provisions/deprovisions across all connected apps. Rich HR integrations (Workday, BambooHR, UKG).

HR-driven automation

Lifecycle Management

Entra ID Governance covers M365 and Azure resources well. Inbound provisioning from HR sources is newer and still maturing.

Maturing

Verdict

Okta leads here, especially for orgs with complex HR systems. Most co-existence designs have HR → Okta → Entra ID sync.

External Identities (CIAM)

Okta Customer Identity Cloud (Auth0) is the gold standard for customer-facing apps. Developer-friendly, highly customizable.

Purpose-built for CIAM

External Identities (CIAM)

Entra External ID (formerly B2C) handles guest access and customer identity but requires more configuration effort.

Getting better

Verdict

Okta/Auth0 is the stronger choice for customer identity. Entra External ID is viable if staying in the Microsoft ecosystem is a priority.

Admin Experience

Purpose-built admin console. Clean, intuitive, designed specifically for IAM workflows. Faster to onboard new admins.

Easiest to manage

Admin Experience

Spread across Entra admin center, M365 admin center, and Azure portal. Powerful but complex. Steeper learning curve.

Fragmented UX

Verdict

Okta wins on day-to-day admin simplicity. This translates to lower IT overhead and faster incident response time.

Need help deciding which platform handles your specific stack?

Decision Guide

Which platform fits your scenario?

Six common enterprise scenarios — and the honest recommendation for each.

Choose Okta when…

You use Workday, BambooHR, or UKG as your HR source of truth

Okta's native HR integrations are unmatched. Automate user provisioning, attribute syncing, and deprovisioning directly from your HRIS — across every app in your stack, not just Microsoft. Cut onboarding from 3–5 days to 30 minutes.

See Workday + Okta integration →

Okta Recommended

Lean on Entra ID when…

Your stack is 90%+ Microsoft and budget is a constraint

If Teams, SharePoint, Azure, and M365 are your primary apps and you're not managing dozens of external SaaS tools, Entra ID with P1 licensing covers the essentials at no extra cost.

See Microsoft 365 plans →

Entra Recommended

Run both when…

You have a mixed SaaS environment with 20+ applications

Okta as the SSO hub, Entra as the authoritative directory for Microsoft workloads. Users get one login experience. IT gets centralized visibility. This is the architecture we deploy most often.

Talk to a co-existence expert →

Co-Existence Recommended

Choose Okta when…

You're building customer-facing or partner portal authentication

Okta Customer Identity Cloud (Auth0) gives developers a flexible, battle-tested CIAM platform with customizable login flows, social login, and progressive profiling — far beyond what Entra B2C offers today.

Explore Okta CIAM options →

Okta Recommended

Lean on Entra ID when…

Zero Trust and device compliance are driven by Intune

Microsoft's tight integration between Entra ID Conditional Access, Intune MDM, and Defender for Endpoint creates a powerful device-aware security posture that's hard to replicate with third-party tools.

See Microsoft 365 security plans →

Entra Recommended

Run both when…

You're acquiring companies or onboarding B2B partners rapidly

Okta's Universal Directory and multi-tenant architecture makes it far easier to federate external organizations than Entra's guest access model. Okta handles external identities; Entra governs internal M365 access.

End-to-end deployment & support

Implementation Approach

How we deploy this in 5 phases

Identity Discovery & Mapping

We audit your existing directory structure — Active Directory, Entra ID configuration, current app inventory, and HR system connections. We identify every app, every group, and every authentication method in play before touching anything.

Okta Tenant Configuration & HR Integration

We stand up your Okta tenant and connect it to your HR system (Workday, BambooHR, etc.) to establish the HR source-of-truth flow. User profiles are created in Okta from HR data — not manually, not from AD alone.

Entra ID / Active Directory Sync

We deploy the Okta AD Agent and configure bidirectional sync between Okta and Entra ID. Microsoft 365 continues to function without disruption. Groups, attributes, and license assignments flow correctly in both directions.

App Migration to Okta SSO

We migrate non-Microsoft applications from their existing authentication methods to Okta SSO — typically in waves, starting with the highest-risk or most-used apps. Each integration is tested before users are cut over.

Policy Governance & Handoff

We configure MFA policies, conditional access rules, and lifecycle automation (joiner/mover/leaver workflows). We document everything and train your IT team — then hand off a clean, governed environment with ongoing support available.

💬 Frequently Asked Questions

We already pay for Entra ID P2. Do we really need Okta?

Maybe not. If your app footprint is predominantly Microsoft and your team is already fluent in the Microsoft admin ecosystem, Entra ID P2 is genuinely powerful. However, the moment you need to manage identity for non-Microsoft SaaS apps at scale, or your HR-to-IT provisioning chain is complex, Okta earns its keep. We can help you audit your current environment and make that call honestly — without trying to sell you something you don't need. Estimate your Okta ROI →

Won’t running two identity platforms create more complexity?

In a poorly designed architecture, yes. In a well-designed co-existence model, no — it actually reduces complexity for IT and for end users. The key is clear ownership: Okta owns the universal directory and app federation; Entra ID owns Microsoft-specific policy and resource access. Users get a single MFA prompt, and IT gains centralized visibility across all apps in one Okta dashboard. See a real co-existence case study →

What happens to our existing Active Directory? Does that go away?

Not necessarily. Okta integrates with on-premises Active Directory via the Okta AD Agent, which runs on-prem and syncs users and groups to Okta. Many organizations run Okta → AD → Entra ID (via Entra Connect) for years as they gradually modernize. We can help you design a migration path that respects your existing infrastructure and moves at the pace your team can sustain.

Can Okta replace Entra ID / Azure AD entirely?

Technically Okta can federate into Microsoft 365 and manage the Microsoft auth experience — but we don't recommend eliminating Entra ID for M365 organizations. Entra ID is tightly woven into M365 licensing, Teams, SharePoint, and Azure RBAC in ways that are difficult and risky to replace. The better model is federation: Okta handles the login experience, Entra ID handles the Microsoft resource governance. Best of both worlds. Compare Microsoft 365 plans →

How long does an Okta and Entra ID co-existence deployment take?

For a mid-market organization (200–1,000 users, 20–50 apps), a well-scoped co-existence deployment typically runs 8–16 weeks from kickoff to full production cutover. That includes discovery, HR integration, directory sync, app migrations, and admin training. Larger orgs with complex legacy systems can run 6+ months. We build a phased plan so you see value at each milestone, not just at the end.

What does this cost compared to Okta Professional Services?

Iron Cove Solutions typically delivers 35–50% cost savings compared to Okta Professional Services for equivalent implementations. We're a specialized boutique — you get senior engineers on every engagement, not junior staff. Our fixed-scope SOWs also mean no surprise overages. Use our cost calculator to estimate savings →
