Defender for Business vs Defender for Endpoint: Which Plan Does Your Business Actually Need?

Microsoft's endpoint protection portfolio can be confusing. Defender for Business and Defender for Endpoint both provide EDR, but they're different products designed for different audiences. For most SMBs on Microsoft 365 Business Premium, this is an easy decision — but understanding the differences helps you know what you have.

Defender for Business (included in Business Premium)

Designed for businesses up to 300 users. The management experience is simplified — fewer configuration options, but sensible defaults and guided setup. Key features:

• EDR with automated investigation and response
• Next-generation antivirus
• Attack Surface Reduction rules
• Threat & Vulnerability Management (simplified)
• Defender for Office 365 P1 (email protection)

Managed from the Microsoft Defender portal or the Microsoft 365 Lighthouse console (for MSPs managing multiple clients).

Defender for Endpoint P1 and P2 (enterprise)

Designed for larger organisations and enterprise security teams. P2 adds:

• Full EDR with 180-day raw timeline data
• Microsoft Threat Experts (managed hunting service)
• Advanced hunting with custom KQL queries
• Advanced Threat & Vulnerability Management
• Device discovery across the network

Which is right for an SMB?

For businesses up to 300 users, Defender for Business is the correct choice. It's included in Business Premium, provides genuine enterprise-grade EDR, and the simplified management experience is appropriate for an MSP managing dozens of clients simultaneously. Defender for Endpoint P2 is overkill for most SMBs and adds significant cost per user. Optimyze recommends and manages Defender for Business for all clients under 300 users.
