Pros

Best for
SMBs already using Microsoft 365 that want endpoint protection close to their existing identity and productivity stack.
Microsoft Defender for Business is a strong first shortlist for companies already standardized on Microsoft 365, Windows, Teams, Outlook, and Entra ID. It brings endpoint detection and response, next-generation antivirus, vulnerability management, attack surface reduction, automated investigation, and remediation into the broader Microsoft environment.
Its biggest advantage for SMBs is consolidation. Teams that already use Microsoft 365 Business Premium may already have Defender for Business included, reducing the need to add another standalone security console.
