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.

Works with Entra Conditional AccessNo MDMB2B guest users

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.
  • PosturePass checks disk encryption, antivirus, firewall, operating system updates, screen lock, and risky remote access tools on Windows, macOS and Linux.
  • Works for B2B guest users, contractors from organizations without Entra, and independent operators.
  • Conditional Access requires Microsoft Entra ID P1, included in Microsoft 365 E3, E5 and Business Premium. Contractors do not need Intune licences.
  • 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.

Microsoft Entra ID all devices list showing a contractor macOS device marked compliant with PosturePass as the verification source.

PosturePass verifies the contractor device and makes the result available to Microsoft Entra ID, where your existing Conditional Access policy grants or blocks access.

Illustrative Entra ID view.

01

Contractor signs in to Microsoft 365

Sign-in, MFA, and identity stay the same.

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 can fix the issue and re-check without contacting IT.

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 sign-in, then every hour.

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.

Windows example

Before and after: the PosturePass agent shows Action required with encryption failing, then shows the device compliant with every control passing
The contractor sees the failed control, resolves it, and rechecks the device without waiting for IT.

CUSTOMER RESULTS

A regulated U.S. company in the insurance industry moved more than 2,000 contractors off VDI in eight weeks.

Frequently Asked Questions

For contractors who only need Microsoft 365 and web applications, yes. If they need legacy thick-client apps or specialized desktop environments, VDI still makes sense for those workloads. Most enterprises find that a large share of contractors only need email, Teams, SharePoint, and web apps.

PosturePass provides a compliance signal that Entra Conditional Access uses alongside your other conditions, such as MFA and location, when making grant or block decisions.

Yes. PosturePass works for external identities, including B2B guests, contractors from organizations without Entra, and independent operators with no MDM.

Conditional Access requires Microsoft Entra ID P1, included in Microsoft 365 E3, E5 and Business Premium. Contractors do not need Intune licences.

Windows, macOS and Linux.

Without the agent, the device cannot be verified, so access to protected resources is not granted. In practice, adoption is high because the agent is lightweight, privacy-respecting, and the alternative is not having access.
