Intune Trusted Certificate Deployment

INTUNE CERTIFICATE TRUST DEPLOYMENT

Build the trust chain before certificate-based access

Trusted root and intermediate certificates must be delivered and validated before Wi-Fi, VPN, SCEP, PKCS or app authentication scenarios depend on them.

Executive Summary​

Trusted Root CA certificates must be deployed before PKCS, SCEP, or imported certificate profiles can be used successfully.

This guide explains the deployment process using Intune Trusted Certificate Profiles.

한국어 요약​

Intune Trusted Certificate Deployment는 Wi-Fi, VPN, SCEP, PKCS, email signing, line-of-business application 접속처럼 인증서 신뢰 체인이 필요한 시나리오의 선행 작업입니다.

Root CA와 Intermediate CA를 올바른 형식으로 배포하고, 대상 그룹과 검증 책임을 명확히 정의해야 인증서 기반 인증 장애를 줄일 수 있습니다.

Prerequisites​

Required certificates:

  • Root CA Certificate
  • Intermediate CA Certificate

Export requirements:

  • DER encoded .CER file
  • Public certificate only
  • No private key (.PFX)

Architecture​

Certificate trust chainCA to managed device
01Certificate AuthorityConfirm root and intermediate CA certificates that must be trusted by devices.
02Export certificateUse DER encoded .CER format and public certificate only.
03Deploy with IntuneCreate Trusted Certificate profile and assign to validated target groups.
04Validate device trustConfirm root and intermediate stores before SCEP, PKCS, Wi-Fi or VPN rollout.

Deployment Process​

Deployment workflowProfile, assignment, validation
01Create profileUse Intune Admin Center, Devices, Configuration Profiles, Trusted Certificate.
02Upload and assignUpload the certificate and target user, device or dynamic groups.
03Deploy and monitorSync devices, review policy status and troubleshoot profile delivery.
04EvidenceRecord validation result before enabling certificate-dependent services.

Recommended execution notes:

  • Start with a pilot group before broad assignment.
  • Deploy the root and intermediate chain in the correct order.
  • Keep certificate owner, renewal date and dependent service documented.
  • Validate both device certificate store and application behavior.

Validation​

Confirm certificate deployment.

certmgr.msc

Verify:

  • Trusted Root Certification Authorities
  • Intermediate Certification Authorities

Deployment Decision Points​

Certificate deployment should be treated as an identity and device trust dependency. Before assigning a Trusted Certificate profile broadly, confirm which downstream scenario needs the certificate: Wi-Fi, VPN, SCEP, PKCS, email signing, browser trust or line-of-business application access. The assignment scope should match that scenario rather than every managed device by default.

Key decisions:

  • whether the certificate is required for user devices, shared devices or servers
  • whether the profile should target users, devices or dynamic groups
  • whether the CA chain requires both root and intermediate certificates
  • how renewal, revocation and CA rollover will be handled
  • who owns validation when certificate-dependent services fail

Operational Best Practice​

  • Pilot first
  • Validate chain trust
  • Document CA hierarchy
  • Maintain renewal process
