Infisical’s Microsoft Intune Connection lets you validate SCEP certificate requests against Microsoft Intune using Client Secrets. When a device enrolls through a SCEP enrollment method configured with Intune validation, Infisical asks Intune to confirm the device’s challenge before issuing the certificate, then reports the outcome back to Intune.
Microsoft Intune is an enterprise App Connection and requires a paid plan.
Prerequisites:
  • A Microsoft Entra ID tenant with Microsoft Intune enabled.
