Microsoft Defender for Business review status on SecurityChecklist: editorial draft, score N/Pub, evidenceLabel unverified. Commercial status is editorial_only, which is not partner acceptance.

Verified pack narrative for diligence: standalone Defender for Business is an AI-powered device security SKU for businesses with up to 300 employees, covering next-generation antivirus, vulnerability management, endpoint detection and response, and automated investigation and response; standalone does not include email protection; list price is $3.00 USD per user per month paid yearly (tax not included).

Inventory ID: E038

Editorial score: N/Pub (null) until E006 score gate clears; never invent a numeric ranking.

Conversion intent (not a ranking input): Partner or demo lead

Many Microsoft estates already have unused device controls. Finish free hygiene before buying seats.

Before turning on a paid Defender for Business SKU

Confirm Windows Update, BitLocker or FileVault, and baseline antivirus are on for company devices
Count users against the 300-employee standalone band and devices against the five-per-user ceiling
Decide whether email protection is already covered by Microsoft 365 Business Premium or a separate email security path
Name who will act on automated investigation findings
Capture OS mix and MDR need in the endpoint requirements builder before partner calls

Product scope from verified pack claims

Per microsoft-defender-business:product-scope, Defender for Business targets businesses with up to 300 employees and covers next-generation antivirus, vulnerability management, EDR, and automated investigation and response. Standalone does not include email protection; Microsoft 365 Business Premium bundling is a separate packaging path. Support for up to five devices per user with no minimum device requirement is pack-cited from the standalone plan listing.

Pricing transparency

Pricing-transparency claim: standalone Microsoft Defender for Business is listed at $3.00 USD per user per month when paid yearly; price does not include tax. Re-check Microsoft and partner quotes before purchase; regional taxes and bundle mixes change the invoice.

Missing pack slots (do not invent)

Security-architecture, admin-identity, and support-response remain missing in pack. SecurityChecklist will not invent encryption matrices, SSO/SCIM detail, or support SLAs for this review until those slots are verified.

Independent standards (vendor-cited)

Independent-or-standards claim cites IDC MarketScape Leader language for Microsoft in modern endpoint security segments. That is vendor-cited analyst marketing, not a SecurityChecklist score or lab validation.
