Select license size in the admin center

Purchase the license for your network from the Microsoft 365 admin center, ensuring it covers enough devices for your site needs.

  2. Search for Defender for IoT.

  3. Choose the license appropriate for the size of your site. There are five different sized licenses ranging from Extra-large for up to 5,000 devices, to extra-small covering a maximum of 100 devices.

    Make sure to select the number of licenses you want to purchase based on the number of sites you're monitoring. You might need to select licenses of different sizes if the number of devices at each site is different.

  4. Complete the purchasing instructions.
