MICROSOFT 365 CONTRACTOR ACCESS

Give contractors Microsoft 365 access. No MDM. No VDI.

Employees go through Intune. Contractors can't. PosturePass checks the device at sign-in and feeds the result to Conditional Access.

Illustrative outcomes based on typical deployments.

Key facts

  • PosturePass verifies the device at sign-in and sends a compliance signal to Microsoft Entra Conditional Access. Existing Conditional Access policies then grant or block access.
  • No MDM, Intune, or management profile is installed on the contractor's device.
  • Posture checks cover disk encryption, antivirus, firewall, OS version, and screen lock on Windows and macOS.
  • Works for B2B guest users, contractors from organizations without Entra, and independent operators.
  • Required licensing: Microsoft Entra ID P1 (included with Microsoft 365 E3). Intune licenses are not required for external users.
  • Failed checks show the user guided remediation steps; most issues are resolved without a help-desk ticket.

How verification fits inside your Entra access flow

Sign-in stays the same. PosturePass adds a device check before access is granted.

01

Contractor signs in to Microsoft 365

02

PosturePass checks the device

A light agent checks encryption, antivirus, firewall, OS version, and screen lock.

03

Entra Conditional Access reads the result

PosturePass sends the compliance signal. Your policies grant or block.

04

Failed devices get guided fix steps

Users resolve most issues themselves in minutes. No ticket.

05

Every check is logged

Timestamped record of result, controls, and remediation.

BYOD endpoint security without full MDM enrollment

Full MDM is the wrong tool for personal and contractor devices. PosturePass verifies the controls that matter without taking over the device.

No management profile

No MDM enrollment on the user's BYOD laptop. No company ownership of a personal device.

No remote wipe, no remote control

PosturePass reads posture and reports a result. It does not push apps, change settings, or wipe data.

Controls still verified

Encryption, antivirus, firewall, OS version, and screen lock are checked at every sign-in.

Why Intune does not cover external users

Cross-tenant enrollment is usually blocked

The contractor's org has to allow MDM from your tenant. Most don't.

Privacy and legal stall rollout

Enrollment puts a management profile on personal devices. HR and legal push back.

PosturePass verifies without enrolling

The agent checks controls. No MDM profile, no remote management, no remote wipe.

If a device fails, the user sees fix steps

Most issues are resolved by the user without a help-desk ticket.
