# Start a Microsoft Defender for IoT trial
This article describes how to set up a trial license and create an initial OT plan for Microsoft Defender for IoT, for customers who don't have any Microsoft tenant or Azure subscription at all. Use Defender for IoT to monitor network traffic across your OT networks.
A trial supports a **Large** site size with up to 1,000 devices. You might want to use this trial with a [virtual sensor](tutorial-onboarding.md) or on-premises sensors to monitor traffic, analyze data, generate alerts, understand network risks and vulnerabilities, and more.
There are two stages to starting a trial for Defender for IoT.
1. Stage 1: [Add a trial license](#add-a-trial-license).
1. Stage 2: [Add an OT plan](#add-an-ot-plan).
Once you set up the trial license and OT plan, you can onboard OT sensors and associate them with this license and plan.
For more information, see [Free trial](billing.md#free-trial).
A trial license can be extended up to 15 days before the trail expires. For more information, see [extend your trial license](license-and-trial-license-extention.md#trial-license-extension).
## Prerequisites
Before you start, you need:
1. An email address to be used as the contact for your new Microsoft tenant.
1. A Microsoft tenant, with Global or Billing admin access to the tenant.
For more information, see [Buy or remove licenses for a Microsoft business subscription](/microsoft-365/commerce/licenses/buy-licenses) and [About admin roles in the Microsoft 365 admin center](/microsoft-365/admin/add-users/about-admin-roles).
1. Credit card details for your new Azure subscription, although you aren't charged until you switch from the **Free Trial** to the **Pay-As-You-Go** plan.
## Add a trial license
This procedure describes how to add a trial license for Defender for IoT to your Azure subscription. One trial license is available per tenant.
To add a trial license with a new tenant, we recommend that you use the Trial wizard. If you already have a tenant, use the Microsoft 365 Marketplace to add a trial license to your tenant.
