Best Endpoint Security for Microsoft 365 Organisations

There is no scored "best endpoint security for Microsoft 365 organisations" on SecurityChecklist. Start with Microsoft 365 estate before agent logos: Defender baselines, MFA, and who will watch alerts usually beat a second console bought for badge theater.

Direct answer (claim-safe)

Pack-verified diligence set (unscored): Microsoft Defender for Business when the org is at or under 300 employees and wants a published standalone $3.00 USD per user per month yearly from-price; Huntress when managed Microsoft Defender Antivirus plus 24/7 SOC is the leftover job; Sophos Endpoint when unified EDR/CryptoGuard and quote-only packaging are under diligence; CrowdStrike Falcon product-scope when a broader platform path is already in evaluation. Scores stay N/Pub.

Many Microsoft 365 tenants already own unused device controls. Finish free work first.

Microsoft estate hygiene before paid agents

Confirm Windows Update, BitLocker, and Defender Antivirus health across Intune or your MDM
Enforce MFA on Microsoft 365 admins and disable legacy auth
Count users against the Defender for Business 300-employee standalone band
Decide whether email protection is already covered by your Microsoft 365 SKU
Capture OS mix and MDR need in the endpoint requirements builder

Buyer-fit scenarios (unscored)

Choose diligence by leftover device response work inside a Microsoft-heavy estate, not by anti-Microsoft marketing.

Standalone device SKU up to 300 employees at pack-cited $3.00 USD/user/month yearly: include Microsoft Defender for Business
Managed Defender Antivirus with published Managed EDR endpoint bands: include Huntress ($8.99 USD per endpoint per month for 50-99 endpoints in pack)
Unified endpoint/EDR with CryptoGuard rollback under quote diligence: include Sophos
Platform product-scope already in RFP: include CrowdStrike Falcon product-scope only; do not invent seat USD

Feature comparison outline (claim-safe)

Compare on jobs: Microsoft-native packaging, managed SOC coverage, ransomware rollback modules, and who owns alert follow-up. Defender for Business standalone does not include email protection per pack.

Commercial status is not acceptance

Microsoft Defender for Business is editorial_only in pack. Huntress, Sophos, and CrowdStrike remain application_pending where marked. Partner pages are not acceptance.
