Azure Intune: Windows

Witness Anywhere: Intune Admin Guide (Windows Physical devices)

Lifecycle Overview

1. The registration script runs on a device, installs the WitnessAI Root CA certificate to the Local Machine trusted root store, generates a device fingerprint, registers with WitnessAI, writes the configuration to the user's registry (`HKEY_USERS\<SID>\Software\WitnessAI`), applies the PAC URL to the system proxy settings, and deploys STunnel for encrypted proxy communication.
2. The flush script can be assigned on-demand to revert all proxy settings, remove the Root CA certificate, uninstall STunnel, and delete the local configuration.

Generate Witness Anywhere Registration Scripts

• In the WitnessAI console, go to Administration → Configuration → Proxy. The Proxy Configuration page opens with a Witness Anywhere section.

• Type your preferred token name in the Key Name field and select the Expiration Date. The Expiration Date should allow time for you to complete the current deployment.

• Click the Generate PAC Token

Download the Intune bundle from the Witness console

1. In the Witness console, open the Download Device Registration Script dialog.
2. Configure the download options:
• Platform: select Intune (Windows).
• Static Domain (Optional): enter the static domain if one is used for your tenant (e.g. witness.ai).
• STunnel (Optional): this toggle controls what the generated detection script validates:
• Enabled: the detection script includes stunnel health logic: it verifies that stunnel is installed under the user profile, the process is running, and it is listening as expected, in addition to the PAC/registry checks.
• Disabled: the detection script contains no stunnel logic and validates only the Witness Anywhere PAC/registry configuration.
3. Click Download.

1. Extract the downloaded bundle. It contains two folders: platform_scripts and remediation_scripts.

1. For this deployment, use the scripts from the platform_scripts folder: flush.ps1 and register_device.ps1.
