Defender for Business or SentinelOne, which fits our SMB?
Both are EDR for SMB, both are more than legacy AV. Differences are tooling, integration, who runs it. No absolute winner, the winner depends on the rest of your stack.
Try this first
- 1Defender for Business: bundled in Microsoft 365 Business Premium, or sold per user. Managed in the same admin portal as the rest of your M365. Strong if you already run Microsoft.
- 2SentinelOne: usually via an MSP, not Microsoft-managed. Stronger detection and ransomware rollback, but you need someone reading the console.
- 3Practically: under 25 staff and self-managed, take Defender and turn on the policies. Over 50 staff with an MSP already on SentinelOne, stay there.
- 4Mixing is possible but not on the same endpoint. Two EDRs on one laptop fight.
When to bring us in
We run both at clients and can shadow you for a month before advising. Ask for a proof of concept, no contract needed.

- Outlook crashes or freezes on large attachmentsUsually the mailbox cache is the culprit, not Outlook itself. Shrinking or relocating usually helps within ten minutes.
- Teams: they cannot hear me, or I hear nothingIn our experience Teams usually picked the wrong audio device after a Windows update or a new headset.
- OneDrive has stopped syncingThe cloud icon is grey or has a warning. Locally changed files are not showing up for colleagues.
