# Block Arc on devices

# Block ServiceNow Arc on user devices {#ariaid-title1}

Release version: Brazil  
Updated October 28, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Stop ServiceNow Arc from starting on specific machines when you need to contain its use, without affecting other installations.

## Before you begin

Role required: sn_ai_governance.ai_steward

## Procedure

1. Navigate to AllAI Control TowerHomeInventoryAssets.
2. Open the ServiceNow Arc agent record.
3. Select the Fleet tab.
4. Select the check box for each instance that you want to block.  
   You can block only instances with an Install Status of Installed. Any instance already in maintenance that you select is left out of the block.
5. Select Block.
6. In the confirmation dialog box, review the people listed under Fleet.
7. Select Block to confirm.

## Result

The Install Status of each blocked instance changes to In Maintenance. Arc can't start on those devices, and the people using them can't launch it until you unblock the instances.
