Okta, Microsoft Entra ID, and CyberArk are often pitched as competitors — they are not. Each owns a distinct layer: workforce SSO, customer identity, and privileged access. This article shows how to combine them into a coherent IAM stack.
The three layers
- Workforce identity (SSO + MFA) — Okta or Entra ID.
- Customer identity (CIAM) — Okta CIC, Entra External ID, Auth0.
- Privileged access (PAM) — CyberArk, BeyondTrust, Delinea.
How they fit together
Workforce IdP issues SSO tokens for SaaS + Entra-joined apps. PAM vaults domain admin credentials and rotates them via CPM. CIAM handles external users separately. Conditional Access (Entra) or Okta policies gate every sign-in.
Choosing the workforce IdP
- Microsoft-heavy shop — Entra ID is the default. Free with M365.
- Best-of-breed SaaS — Okta has the deepest OIN catalog.
- Hybrid — Both, with Okta on top of Entra (federation), or vice versa.
Detailed responsibilities per layer
- Workforce SSO (Okta / Entra ID) — issues SAML/OIDC tokens to SaaS and federated apps; centralises MFA, device posture, lifecycle.
- Customer identity (CIAM) — Auth0, Okta CIC, Entra External ID, AWS Cognito, Firebase Auth. Tuned for high-friction-free signup, social login, and abuse detection.
- Privileged Access (CyberArk / Delinea / BeyondTrust) — vaults domain admin credentials, rotates secrets, records sessions, brokers just-in-time access for break-glass accounts.
Conditional Access vs Okta policies
Conditional Access is the policy engine that decides whether a sign-in should succeed. Both Entra ID and Okta express policies in a "if X then require Y" form. The real differences show up in the signals they accept and the actions they can take.
- Entra Conditional Access — device compliance (Intune), risk signal (Entra ID Protection), location, app sensitivity. Tightly tied to Microsoft Defender signals.
- Okta policies — broader 3rd-party signals (CrowdStrike, SentinelOne, Netskope), behaviour detection, per-app policies, and a more visual rule builder.
- PAM gating — CyberArk can call either IdP to enforce MFA on every privileged credential retrieval, even if the user is already SSO'd.
PAM vault mechanics
Privileged Access Management sits behind SSO, not in front of it. The vault stores admin credentials encrypted at rest; users request access via a web portal or CLI; the vault brokers the connection (SSH/RDP/HTTPS), rotates the secret after use, and records the session for audit. CyberArk's CPM (Central Policy Manager) automates rotation against AD, AWS IAM, databases, and network gear.
- Just-in-time access — credential is valid only for the requested window.
- Session isolation — vault brokers the connection; the human never sees the password.
- Audit trail — keystroke-level recording, indexed for forensic search.
- Health check — vault verifies each credential is still valid; stale ones are rotated automatically.
Federation patterns
- Okta as primary, Entra as downstream — Okta issues the workforce SSO session; Entra issues tokens for Microsoft 365 and Azure resources.
- Entra as primary, Okta as downstream — common in M365-heavy shops that want Okta's broader SaaS catalogue.
- PAM behind either IdP — CyberArk accepts SAML/OIDC from either; configure SSO so admins do not maintain separate PAM credentials.
Pricing considerations
- Entra ID — free tier included with M365; P1 and P2 add Conditional Access, Identity Protection, and Privileged Identity Management.
- Okta — per-user pricing; Workforce and Customer Identity are separate products with separate licensing.
- CyberArk — per-privileged-user; pricing scales with the size of the vault and the rotation cadence.
Common pitfalls
- Mixing workforce and customer identity — never reuse the same IdP for both; the policies are different.
- Skipping PAM for cloud admins — AWS root, Azure Global Admin, GCP Org Admin are all credentials; vault them.
- Conditional Access without device compliance — the policy fires only when the device signal exists; if Intune isn't deployed, the rule is a no-op.
- No break-glass account — keep two emergency accounts outside the IdP so a misconfigured policy can't lock the org out.
FAQ
- Do I need both Okta and Entra? Not necessarily. If you are Microsoft-heavy, Entra is enough. If you have many SaaS apps outside the Microsoft ecosystem, Okta adds value.
- Can CyberArk replace my IdP? No. PAM is a separate layer; you still need an IdP for workforce SSO.
- What about passkeys? Both Okta and Entra support FIDO2 / passkeys natively. Plan a phased rollout tied to your high-value apps first.
- What about AI agents? Use machine identities (workload identity federation) instead of personal credentials; vault the long-lived secrets and issue short-lived tokens.
Migration playbook and rollout strategy
Most teams migrate to Okta, Entra, or CyberArk in waves rather than a big-bang cutover. A safe sequence is: stand up the new IdP in a pilot OUs, federate 5–10 non-critical SaaS apps first, enable Conditional Access or Okta policies in report-only mode for two weeks, then enforce. CyberArk typically lands last, after the IdP federation is stable.
- Pilot scope — one business unit, one critical app, fewer than 200 users.
- Rollback plan — keep the legacy IdP reachable for 30 days; document a fallback break-glass procedure for every privileged role.
- Communicate early — send a 30-day, 7-day, and 1-day reminder to users explaining the new login flow and what to do if MFA fails.
- Audit before enforcement — run sign-in logs through Log Analytics or Splunk for two weeks; fix false positives before flipping the policy from report-only to enforce.
