Identity Platform Consolidation
Consolidated three IdPs into Microsoft Entra with SSO, MFA, and conditional access.
Key results
- IdP consolidation 3→1
- MFA coverage 100%
- SSO applications +62
Context
A regional healthcare system operated three identity providers inherited from prior M&A activity. Clinicians working across facilities had multiple credentials; access reviews were complex; security posture was inconsistent across the three identity islands.
Challenge
Identity consolidation in healthcare required maintaining clinical-workflow continuity during the transition. Cutover during any specific window risked clinicians being unable to access patient systems if anything went wrong.
Approach
Thoughtwave delivered a 6-month identity consolidation onto Microsoft Entra: federation from the three source IdPs, phased migration by user population, conditional-access policy alignment, and MFA rollout across the entire identity footprint. The zero-downtime-per-user approach ensured no clinician lost access during cutover.
Outcomes
Identity providers consolidated from 3 to 1; MFA coverage reached 100% across the identity footprint; SSO applications expanded 62 apps because the consolidated identity layer made new-app onboarding straightforward.
