Microsoft Defender for Business review
A focused endpoint security subscription with EDR and centralized controls for small businesses.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Microsoft Defender for Business is an endpoint security solution for small and medium-sized organizations with up to 300 users. It combines next-generation antivirus with ransomware attack disruption, vulnerability management, attack surface reduction, endpoint detection and response, automated investigation and remediation, centralized management, and monthly security summary reporting. Protection covers Windows, macOS, iOS, and Android devices, with web and API access for administration and integration.
The listed plan costs $3 per user per month with annual billing and includes up to five devices per user. It also includes a 30-day free trial. The plan covers core endpoint protection, vulnerability management, EDR with automatic attack disruption, and automated investigation and remediation. Organizations can choose the standalone subscription or receive the product through Microsoft 365 Business Premium, while server protection is available as an add-on. This makes the offering straightforward for teams that need managed endpoint security without selecting among multiple listed tiers.
Its strongest fit is for organizations already operating within Microsoft’s ecosystem. Centralized management is available through the Microsoft Defender portal, with integrations for Microsoft Intune, Microsoft 365 Lighthouse, RMM tools, PSA software, SIEM platforms, and programmatic APIs. Those connections support security operations, reporting, and administrative workflows across supported devices. Businesses needing protection beyond the listed desktop and mobile scope should account for the separate server add-on, and organizations above 300 users or requiring more than five devices per user should look for an alternative. For its intended audience, Defender for Business offers a focused combination of antivirus, endpoint response, vulnerability management, and Microsoft-aligned administration.
