Quickstart: Get started with Defender for IoT

This quickstart takes you through the initial steps of setting up Defender for IoT, including:

  • Add Defender for IoT to an Azure subscription
  • Identify and plan solution architecture

You can use this procedure to set up a Defender for IoT trial. The trial provides 30-day support for 1000 devices and a virtual sensor, which you can use to monitor traffic, analyze data, generate alerts, understand network risks and vulnerabilities and more.

Prerequisites

Before you start, make sure that you have:

  • An Azure account. If you don't already have an Azure account, you can create your free Azure account today.

  • Access to an Azure subscription with the subscription Owner or Contributor role.

If you're using a Defender for IoT sensor version earlier than 22.1.x, you must also have an Azure IoT Hub (Free or Standard tier) Contributor role, for cloud-connected management. Make sure that the Microsoft Defender for IoT feature is enabled.

Permissions

Defender for IoT users require the following permissions:

Permission Security reader Security admin Subscription contributor Subscription owner
Onboard subscriptions and update committed devices
Onboard sensors
View details and access software, activation files and threat intelligence packages
Recover passwords

For more information, see Azure roles.

Supported service regions

Defender for IoT routes all traffic from all European regions to the West Europe regional datacenter. It routes traffic from all remaining regions to the East US regional datacenter.

If you're using a legacy experience of Defender for IoT and are connecting through your own IoT Hub, the IoT Hub supported regions are also relevant for your organization. For more information, see IoT Hub supported regions.

Identify and plan your OT solution architecture

If you're working with an OT network, we recommend that you identify system requirements and plan your system architecture before you start, even if you plan to start with a trial subscription.

Note

If you're setting up network monitoring for Enterprise IoT systems, you can skip directly to Add a Defender for IoT plan for Enterprise IoT networks to an Azure subscription.

When working with an OT network:

  • To deploy Defender for IoT, you'll need network switches that support traffic monitoring via a SPAN port and hardware appliances for NTA sensors.

    For on-premises machines, including network sensors, on-premises management consoles and for air-gapped environments you'll need administrative user permissions for activities. These include activation, managing SSL/TLS certificates, managing passwords, and so on.

  • Research your own network architecture and monitor bandwidth. Check requirements for creating certificates and other network details, and clarify the sensor appliances you'll need for your own network load.

    Calculate the approximate number of devices you'll be monitoring. Devices can be added in intervals of 100, such as 100, 200, 300. The numbers of monitored devices are called committed devices. For more information, see What is a Defender for IoT committed device?

Microsoft Defender for IoT supports both physical and virtual deployments. For physical deployments, you'll be able to purchase certified, preconfigured appliances, or download software to install yourself.

Add a Defender for IoT plan for OT networks to an Azure subscription

This procedure describes how to add a Defender for IoT plan for OT networks to an Azure subscription.

To onboard a Defender for IoT plan for OT networks:

  1. In the Azure portal, go to Defender for IoT > Pricing.

  2. Select Add plan.

  3. In the Purchase pane, define the plan:

    • Purchase method. Select a monthly or annual commitment, or a trial. Microsoft Defender for IoT provides a 30-day free trial for the first 1,000 committed devices for evaluation purposes.

      For more information, see the Microsoft Defender for IoT pricing page.

    • Subscription. Select the subscription where you would like to add a plan.

    • Number of sites (for annual commitment only). Enter the number of committed sites.

    • Committed devices. If you selected a monthly or annual commitment, enter the number of assets you'll want to monitor. If you selected a trial, this section doesn't appear as you have a default of 1000 devices.

    For example:

  4. Select the I accept the terms option, and then select Save.

Your OT networks plan will be shown under the associated subscription in the Plans grid. For more information, see Manage your subscriptions.

Add a Defender for IoT plan for Enterprise IoT networks to an Azure subscription

Onboard your Defender for IoT plan for Enterprise IoT networks in the Defender for Endpoint portal. For more information, see Onboard Microsoft Defender for IoT in the Defender for Endpoint documentation.

Once you've onboarded a plan for Enterprise IoT networks from Defender for Endpoint, you'll see the plan in Defender for IoT in the Azure portal, under the associated subscription in the Plans grid, on the Defender for IoT > Pricing page.

For more information, see Manage your subscriptions.
