Microsoft Defender vs SentinelOne

Microsoft Defender for Business comes included with Microsoft 365 Business Premium, while SentinelOne is a dedicated endpoint protection platform. The right choice depends on your existing stack and security requirements.

Our Verdict

For businesses already on M365 Business Premium, Defender provides solid baseline protection. SentinelOne offers more advanced autonomous response for organizations needing deeper endpoint security. Either way, we recommend adding MDR (like Huntress) for human-led threat response.

Frequently Asked Questions

Defender provides baseline protection but lacks autonomous response, cross-platform depth, and human-led investigation. Most businesses should layer MDR on top of whichever endpoint platform they choose.
