The Missing Piece in Your Microsoft 365 Contractor Migration
Verify unmanaged contractor and third-party devices before they access your Microsoft 365 environment.
No MDM. No Intune enrollment. No VDI. Starts at $3/user/month.
Ensure works with your existing Microsoft 365, Entra ID, and Conditional Access policies.
1.4M+ devices verified across regulated enterprises

What Ensure makes possible
One lightweight agent to verify contractor devices, enforce posture, and log audit evidence for Microsoft 365 access.
89%
lower contractor access cost
Verify contractor devices before Microsoft 365 access
Ensure checks device posture on unmanaged contractor endpoints and sends the result to your access policies, so Microsoft 365 stays protected without keeping VDI in place.
1‑Click
audit export
Enforce device posture at the point of access
Every access check creates a timestamped compliance record with the device, checks performed, result, and remediation status — ready to export when security, audit, or compliance asks.
< 5 min
average setup time
Onboard contractors fast without help desk overhead
Contractors receive a link, install the lightweight agent in minutes, and can get verified for Microsoft 365 access the same day. Most remediate issues themselves without opening a support ticket.
Your situation
Which problem are you solving?
Migration Owner
I'm trying to get contractors off VDI
Contractors are still stuck on VDI because their devices are unmanaged. See how to move them into Microsoft 365 and Windows 365 without lowering security.
CISO / Security Architect
I need proof contractor devices meet policy
Your team needs evidence that unmanaged devices meet security requirements at the moment of access. See what Ensure verifies, logs, and exports.
In production
How a regulated enterprise moved 2,000+ contractors off VDI and into Microsoft 365
Including partners from Accenture, Deloitte, and other global service providers.
Three steps
How Ensure verifies devices before Microsoft 365 access
Contractors attempt access, device posture is checked, and compliance evidence is logged automatically.
Contractor attempts to access Microsoft 365
Ensure checks the device and sends the result to your access policy before access is granted. No extra login flow. No corporate enrollment required.
Device posture is verified in seconds
Ensure verifies key security controls such as encryption, antivirus, firewall, OS version, and screen lock. If something is missing, the contractor gets guided steps to fix it.
Compliance evidence is logged automatically
Each access check creates a time-stamped record with the user, device, checks performed, result, and remediation status — ready to export when audit or security asks.
Why not just...
Every alternative breaks somewhere. Here is where they fail for contractor access.
Ensure works with Microsoft 365 by adding device verification for unmanaged users — without the cost and complexity of VDI or full MDM enrollment.
| Alternative | Where it breaks |
|---|---|
| Keep VDI for contractors | Defeats the migration. You keep paying for VDI after rolling out Microsoft 365. |
| Web-only access restrictions | Creates a degraded experience, breaks common workflows, and pushes contractors into workarounds. |
| Issue managed devices | Too expensive and too slow for large, rotating contractor populations. |
| Enterprise browser (Island, Talon) | Higher cost, browser change required, and more product than most teams need for basic device posture. |
| Accept the risk | Security will not sign off, and audit will not accept the gap. |
| Ensure Endpoint | $3/user/month. No MDM enrollment. Entra Conditional Access integration. Audit evidence. Live in days. |
