Microsoft Defender for IoT - OT Site License — Pricing, Billing & What's Included

Microsoft Defender for IoT - OT Site License is a site-based Commercial subscription for licensing Microsoft Defender for IoT at an operational technology site, because the CSP catalog sells it by OT site-size tier rather than by named user. The available Commercial tiers are XS, S, M, L, and XL, each on a one-year term.

A Microsoft Defender for IoT - OT Site License includes Commercial use rights for Microsoft Defender for IoT for the selected OT site-size tier, because the catalog unit of measure is an OT site license. The Commercial options support a one-year commitment with either annual upfront billing or monthly billing.

Microsoft Defender for IoT - OT Site License does not include Microsoft 365 user licenses, other Microsoft security products, Azure services, deployment labor, or hardware unless those are separately quoted, because the source catalog only identifies the OT site license itself. Buyer-owned or partner-provided sensor hardware, networking equipment, cabling, and implementation services should be confirmed with IT Partner before purchase.

Microsoft Defender for IoT - OT Site License is licensed per OT site-size tier, because the Commercial catalog lists XS, S, M, L, and XL site licenses rather than per-user seats. Do not treat it like a Microsoft 365 per-user security add-on; the correct site tier must be validated before ordering.

Do not assume one OT Site License covers multiple physical or logical OT sites, because the catalog describes the unit as an OT site license selected by size tier. If your organization has several plants, production sites, or segmented OT environments, IT Partner should confirm Microsoft’s current site definition and sizing rules before you buy.

Commercial customers can buy Microsoft Defender for IoT - OT Site License on a one-year term with annual upfront billing or monthly billing, because both billing frequencies are shown in the CSP catalog for each XS, S, M, L, and XL tier. Annual upfront is the lower-cost payment posture shown in the catalog, while monthly billing spreads payment across the same one-year commitment.

No, the source catalog does not show a trial SKU for Microsoft Defender for IoT - OT Site License. A Commercial buyer should plan a sizing and readiness review before purchase rather than relying on a no-cost trial conversion path.

You should choose the XS, S, M, L, or XL tier only after validating Microsoft’s current OT site sizing rules, because the catalog identifies the tiers but does not define device counts, IP counts, traffic volume, or topology thresholds. IT Partner can review the intended site scope and confirm the live CSP SKU before order placement.

No, Microsoft Defender for IoT - OT Site License does not include Microsoft Teams, Microsoft 365 Copilot, or Microsoft 365 productivity licenses, because the catalog entry is a site-based Defender for IoT OT license. If users also need Teams, Copilot, or Microsoft 365 apps, those subscriptions must be licensed separately.

Do not assume Microsoft Defender XDR, Defender for Endpoint, Microsoft Sentinel, or other security services are included, because the source catalog lists only Microsoft Defender for IoT - OT Site License. Integration or adjacent security licensing should be scoped separately with IT Partner based on the customer’s tenant, Azure, and security architecture.

Prerequisites should be confirmed before ordering, because the source catalog does not state the required Azure subscription, Defender portal configuration, sensor version, hardware appliance, or networking prerequisites. For an OT deployment, IT Partner should validate onboarding, sensor placement, hardware sourcing, and tenant readiness against current Microsoft documentation.

Microsoft Defender for IoT - OT Site License is intended to license Microsoft Defender for IoT for an OT site, but specific current capabilities such as asset visibility, OT network monitoring, threat detection, and alerting should be confirmed against Microsoft documentation before purchase. This conservative approach matters because the CSP catalog identifies the license and tier structure, not the full technical feature matrix.

No license by itself guarantees compliance, because compliance depends on configuration, monitoring coverage, operational processes, evidence retention, and the customer’s regulatory scope. Microsoft Defender for IoT - OT Site License can be part of an OT security program, but compliance mapping should be reviewed with IT Partner and the customer’s governance team.

Start with an OT site inventory and sizing review, because the purchase decision depends on selecting the correct XS, S, M, L, or XL site tier. IT Partner should then confirm the live CSP SKU, billing choice, prerequisites, deployment approach, and renewal timing before the subscription is ordered.

A CSP partner transfer or reseller change should not require service downtime when handled correctly, because the Microsoft tenant and service configuration can remain in place while the partner relationship and subscription administration are updated. IT Partner should review the current subscription, term, billing status, and partner-of-record process before initiating the transfer.

For the same Microsoft SKU, site tier, term, and billing frequency, the Microsoft catalog basis is the same, because the underlying CSP offer is the same product configuration. The final invoice can still vary due to taxes, currency, partner services, support bundles, or commercial terms, so IT Partner should confirm the quote before transfer.

At renewal, the customer should reconfirm the OT site tier, billing option, and current CSP terms, because Microsoft catalog rules and the customer’s OT footprint can change over time. IT Partner can help align renewal timing, avoid accidental under-licensing, and decide whether annual upfront or monthly billing is better for the next one-year term.

Mid-term cancellation rights are governed by the current CSP and New Commerce rules at the time of purchase, because this is a one-year Commercial subscription rather than a trial. Buyers should confirm the cancellation window, refund rules, and operational impact with IT Partner before placing the order.

Do not assume a mid-term upgrade or downgrade is always available, because site-tier changes are controlled by the current CSP catalog and Microsoft subscription rules. If your OT footprint may change, IT Partner should confirm change options before purchase and again before renewal.

This listed offer is a Commercial Microsoft Defender for IoT - OT Site License, because the catalog segment for this page is Commercial and the source also shows Education availability separately. Government customers needing GCC or GCC High, nonprofits seeking charity eligibility or grants, and schools distinguishing student versus faculty licensing should not assume this Commercial SKU is the right purchasing path; IT Partner should validate the correct segment, residency expectations, and eligibility before quoting.
