Pricing

TierPriceBillingNotes
Defender for Business$3/user/moAnnualStandalone or bundled with M365 Business Premium

Free trial available. No free tier.

What You Get

  • Endpoint Detection & Response (EDR) for SMB scale
  • Next-generation antivirus with behavioral detection
  • Threat & vulnerability management across endpoints
  • Automated investigation & response to reduce manual toil
  • Microsoft 365 integration (Exchange, Teams, SharePoint visibility)

Strengths

  • Economical within Microsoft ecosystem. Per-user licensing covers multiple devices, and pricing is aggressive if you’re already paying for M365.
  • Solid detection rates backed by Microsoft’s threat intelligence.
  • Low friction for Microsoft shops. Native integration means fewer API headaches and faster onboarding.

Weaknesses

  • Microsoft ecosystem dependency. Works best when you’re all-in on 365; standalone value diminishes in heterogeneous environments.
  • Licensing complexity. Inclusion in M365 Business Premium tiers creates confusion around what’s actually included.
  • Requires tuning. Out-of-box false positive rates can be high; expect to invest in alert tuning.

Social Proof

G2: 4.4/5 (300+ reviews)
Our Score: 7.8/10

Bottom Line

Solid, competent SMB EDR that punches above its weight if you’re already in the Microsoft ecosystem. Price-to-value is hard to beat for M365 customers. Skip it if you need platform-agnostic tooling or deep customization.
