title: Manage EIoT monitoring support | Microsoft Defender for IoT description: LearnCalculate detected enterprise IoT devices to assess standalone licensing needs and learn how to manage yourcancel EIoT monitoring support within Microsoft Defender for IoT. ms.date: 06/12/07/03/2026 ms.topic: how-to ms.custom: - msecd-doc-authoring-1014 This article describes how to:

  • Calculate the devices detected in your environment so that you can understand if you need extra, standalone licenses.
  • Cancel support for enterprise IoT monitoring with Microsoft Defender for IoTIoT.

If you're looking to manage OT plans, see Manage Defender for IoT plans for OT security monitoring.

  • One of the following sets of licenses:

    • A Microsoft 365 E5 (ME5) or E5 Security license and a Microsoft Defender for Endpoint P2 license

    • A Microsoft Defender for Endpoint P2 license alone

    For more information, see Enterprise IoT security in Microsoft Defender XDR.

  • Access to the Microsoft Defender Portal as a Security administrator

    • Obtain a standalone,standalone Enterprise IoT trial license

    This procedure describes how to start using a trial, standalone license for enterprise IoT monitoring, for customers who have a Microsoft Defender for Endpoint P2 license only.

    Start your enterprise IoT trial using the Microsoft Defender for IoT - EIoT Device License - add-on wizard or via the Microsoft 365 admin center.

    To start an Enterprise IoT trial:trial:

    1. Go to the Microsoft 365 admin center > Marketplace.

    For more information, see Enterprise IoT free trial.

    • You're an ME5/E5 Security customer and thinks you need to monitor more devices than the devices allocated per ME5/E5 Security license
    • You're a Defender for Endpoint P2 customer who's purchasing standalone enterprise IoT licenses

    To calculate the number of devices you're monitoring::

    1. In the Defender portal, select Assets > Devices to open the Device inventory page.

    2. Round your total to a multiple of 100 and compare itthe rounded total against the number of licenses you have.

    For example:

    Purchase standalone, per-device licenses if you're an ME5/E5 Security customer who needs more than the five devices allocated per license, or if you're a Defender for Endpoint customer who wants to add enterprise IoT security to your organization.

    To purchase standalone licenses:licenses:

    1. Go to the Microsoft 365 admin center Billing > Purchase services. If you don't have this option, select Marketplace instead.

    This procedure describes how to turn off enterprise IoT monitoring in the Defender portal, and is supported only for customers who don't have any standalone, per-device licenses added on to Microsoft Defender.

    Turn off the Enterprise IoT security option if you're no longer using the service.

    To turn off enterprise IoT monitoring:

    1. In the Defender portal

      To turn off enterprise IoT monitoring:

      1. In the Defender portal, select Settings > Device discovery > Enterprise IoT.

      2. In the Defender portal, select Settings > Device discovery > Enterprise IoT.

      3. Select Cancel plan. ThisThe Cancel plan page is available only for legacy Enterprise IoT plan customers.

      After you cancel your plan, the integration stops and you'll no longer get added security value in Microsoft Defender, or detect new Enterprise IoT devices in Defender for IoT.
